Irregular heartbeats may lead to an imbalance in the work of the heart and disrupt its ability to pump blood
Natural that ينقبض heart and flattens, and issue thus pulse heart heart beat, regularly all the time, but it also is natural that this will change regularity depending on factors and effects experienced by the human body usually at different times of the day or night, such as high heartbeat if done physical exertion, or if high fever, or other cases which differs natural systems heartbeat.
And about the «natural changes in heartbeat systems there« abnormal changes in heartbeat systems called «heart rhythm disorders» (heart arrhythmias) .. When a patient complains or a healthy person of any symptoms related to the uncertainty in the presence of disturbances in the rhythm of the heartbeat, the doctor can perform tests and tests to discover the extent of the disorder in the rhythm of the heartbeat, and what kind of this disorder, and what is its origin, and its negative potential, and how need to be addressed .. Then what is the desired objective reach of the treatment, and what are the means of treatment, ie Are they focused on making changes in the behavior pattern of life or avoid eating certain food or avoid eating certain medications, or advice to start taking medicine or multiple drugs, or conduct therapeutic intervention (interventional) into the heart through a catheter (cardiac catheterization) or applying an electric shock to the heart or use a machine is implanted in a body called cardioverter - defibrillator »(IUCD) or planting regulate heartbeat tool called« governing or regulating »(cardiac pacemaker).
Irregular heartbeat
* Heartbeat being in accordance with a special system to ensure that the heart to pump blood to the major arteries emerging from him in order to be connected this blood pumped continuously and permanently to the different organs in the body. Because different organs in the body need to be blood and it contains materials to live and live and be able to do its job, it is necessary to provide them with blood according to accurate system ensures two things: I do not get tired heart pump and can work efficiently all the time, in other words, that The heart contracts and then relaxes and then The then relaxes contracts and so forth. Second, is to ensure the flow of blood to different organs in the body permanently and continuously so the members have need of oxygen and glucose and proteins and fats and minerals, vitamins and other important elements needed for the work and life members.
Thus, the heart beats per include both phases of cardiac contractility (heart contraction) and diastole heart (heart relaxation), and therefore said: heart fails.
According to the medical definition, uses the term 'heart rhythm disorders to describe any kind of disturbance in the rate (rate) or in rhythm (rhythm) heart beat. This includes either the heart to beat faster or slower than 'normal', or it beats irregularly.
There many abnormal factors can affect the heart rhythm, heart attack or not a chemical balance in the blood or the presence of unhealthy levels of hormones. There are also some materials or medicines that can cause heart rhythm disturbances.
A symptom of arrhythmias
* One of the most important symptoms of heart disorders is throbbing (PALPITATION), which is a medical terminology used to describe various types of feeling that there is something abnormal heartbeat. It is therefore important that one of us understand what is meant by this word. Palpitations beginning is the feeling of something either in the chest area, specifically in the area of the heart the left side of the chest, or in the neck area. And there is a 'feeling' multiple any of them apply to describe throbbing, such as:
* Feeling that heartbeat shaking chest.
* Heart feeling that shaking the entire body.
* Heart feeling that knocks beats and the chest wall.
* Including feeling like a bird flutter in the chest.
* Feeling that one heartbeat had fallen.
* Feeling unusually strong pulse in the chest up to the neck.
In addition to the throbbing, there are other symptoms may accompany the infection heartbeat disorders, some of which is important because it can indicate a serious kind of heartbeat disorders, some of which do not reflect any degree of risk, namely:
* Heart beat faster or slower than normal.
* For Kharijites constriction (extrasystole) any lack of some pulses or incomplete.
* Dizziness or lightness, vertigo (dizziness), which gets serious arrhythmias.
* Fainting or unconsciousness and loss of consciousness (syncope) is what is happening in serious arrhythmias.
* Chest pain (angina).
* Shortness of breath (dyspnoea).
* Pale skin color of the skin.
* Sweating.
Many reasons
* Why get heartbeat disorders? Arrhythmias are many reasons, including the fact that there are people born with the speed of irregular heart, and people can happen to have a heart rhythm disorder if they smoked or drank alcohol or coffee. The drug can also be the cause for disturbances in heart rhythm. There are people happen to have a heart rhythm disorder because eating slimming tablets or drugs treatment of colds or cold.
Can also cause many kinds of heart disease for heart rhythm disorders. The common cardiac causes of arrhythmias are heart attacks, cardiac hypertrophy caused by high blood pressure, valve disease, and many others. In contrast, there other medical conditions can lead to abnormal heart rhythms, such as anemia or increasing the activity of the thyroid gland, pregnancy or other.
Seriousness of the situation
* Where it comes from risk heartbeat disorders? There are several types of heart rhythm disorders. And disturbances in heart rhythm that starts in the atria called atrial arrhythmias. And disorders that begin in the ventricles called ventricular arrhythmias. In general, ventricular arrhythmias are more serious than atrial arrhythmias.
Most arrhythmias are kind of atrial arrhythmias, and so often they are not serious. But if the person feels no irregular heart beat and thought that the irregularity that may be troublesome in heart rhythm, he should see his doctor without delay. So that certain types of arrhythmia can be fatal. Often these types is associated with cardiovascular disease, which may have one or accompanied by dizziness, dizziness or fainting. The cause serious heart rhythm disorders is that irregular heartbeats can lead to an imbalance in the work of the heart, and disrupts the ability of the heart to pump enough blood. Which consequently may lead to low blood pressure and death.
It may not affect heart rhythm disorders on blood pressure but that the blood may not be pumped as a whole out of the heart with every strike, which could lead to the formation of clots or blood clots, within one of the heart chambers.And therefore can later be free blood clots formed in the heart chambers, and transmitted to the brain, leading to strokes.
Diagnostic process
* When you go to a doctor complaining of palpitations, doctor listens carefully to the story of the patient's complaint and precedents health events experienced by. Then conduct clinical examination of the heart and arteries and the rest of the important parts of the relationship does go, then you can ask your doctor to patient testing other to see if a patient has disorder heart rhythm or not, and to learn the style and type of the disorder, and to find out what is the cause.
An important initial tests and basic planning electrocardiogram (ECG or EKG). It does not take this test only a few minutes, during which put some electrodes on the patient's chest and on the outskirts of the hands and feet, and to record the movement of electricity flow within the heart, any electrical pulses to the heart.
As the heart rhythm disorders appear and disappear, and probably will not get all the time, it is possible not to show anything on the drawing planning electric heart. In this case, it could ask the doctor from the patient that is being tested «Holter ECG, that is a planning device is installed portable electric heart, called a Holter heart monitor. This device records the heart's electrical impulses throughout the full 24 hours, in the same way that recorded cardiac electrical layout.
If the heart rhythm disorders occur every few days or every few weeks, the patient can wear a recording device for longer periods, and take the initiative to run when feeling a heart rhythm disorder has, be recorded electrocardiogram these disturbances and the quality and form Kahrbaúatha. Then the recorded information is transferred over the phone to the doctor for analysis. And this process is called heart monitor over the phone.
It is important to know what is the cause of heart rhythm disorder. To this may be your doctor tests for heart and blood-pressure, blood sugar, levels of thyroid hormones in the blood.
When the doctor can examine the causes of heart rhythm disorders, and to know the medicines that can be used to address them.
If the doctor felt concerned because there are abnormal heart rhythms in the patient, he or she can accept the patient in the hospital for observation heartbeat has.
Processing stages
* Based treatment of heart rhythm disorders disorders and style on the degree of danger. There are many types of heart rhythm disorders do not need any treatment.
If the patient has fallen strikes bettered his heart, the doctor asked him reduce caffeine intake. A reduction of caffeine intake enough sometimes to restore heart rhythm to normal. In other cases, it may be sufficient medicines for heart rhythm back to normal. In some cases, arrhythmias, can give the patient long-term drugs for the prevention of heart rhythm disturbances. If all else fails the previous procedures in the treatment of cardiac arrhythmia, it could resort to other measures. The doctor tries to restore normal heart rhythm by exposing the heart to electric shocks. This procedure is called cardioversion electric shock or Calendar electrical cardioversion.
The resulting heart rhythm disorders sometimes overactive certain areas of the heart. In this case, the doctor inserts a tube through accurate a blood vessels to the heart, to damage the electrical pathways in these areas and that causes an alert electrically plus. And this procedure is called damage fabric carrier for electrical alerts by electrical frequencies. In cases where the heart rhythm rate too slow, can implant a device called pacemakers even keeps heart rhythm rate at a certain level. In cases in which the heart rate is very fast, can be planted remover fibrillation by surgery. The alert defibrillator while heart rate up to a serious extent, it sends an electric shock to the heart to bring it back to normal.
And sometimes there is a need in some kind of heartbeat disorders to give drugs «blood مميعات» to prevent the formation of clots in the heart.
How do you measure your heart?
* It is important that everyone knows how to measure the speed of the pulse has. And everyone can feel pulse on the face subcontractor to his wrist, at the near edge of his thumb, any where to put the time in the left wrist. One has only to put my index and middle finger of his right hand on that area in the left wrist, and starts counting the blows can feel it for 15 seconds (quarter minutes), or for a period of 30 seconds (half a minute). Then multiplies the number you got it in four or two, the former would receive the heartbeat per minute. With this measure the speed of the pulse.
Still another is an assessment «irregular heartbeat, and it is one that checks in the sense of how long interval between each pulse and pulse that followed, and the size of the power of each pulse. The mark irregular rhythm of the heart beat is that the intervals between a series of pulses to be equal, and the one that do not fall some of the pulses, and the size of the force equal impulses.
Throbbing prevention to maintain a healthy heart
* The best way and influential and useful to prevent serious heart rhythm disorders is to maintain a healthy heart. The following ten tips contribute to one of us in the province on heart health has, namely:
* You should not smoke.
* You have to exercise physically active under the supervision of a doctor.
* You have to deal with a balanced healthy food rich in fiber poor in fat.
* Should test the level of cholesterol in the blood, if high you should set for be within normal limits.
* You can measure blood pressure on a regular basis. You should you seize if it is high, only to return to normal limits.
* You have to reduce the weight if was a plus.
* You have to play sports regularly.
* You have to test the level of sugar in the blood. If high, you should set for return within normal limits.
* You have to gain enough sleep at night.
* You have to control and dominate the psychological tensions in life and ease its effects on you.
It is important to note that if one has heart disease of any kind or degree, he should consult his doctor before starting an exercise program or aerobics Weight Loss Program.
Understanding the mechanism for heartbeat disorders
* Understand the mechanism of action of the heart is the key to understand the mechanism of evolution and for abnormal heart rhythms. The heart is the most important muscle in the body, and the heart are two aspects the left side and the right side. In each side of the heart two rooms: atrium (ATRIUM) and ventricle (VENTRICLE).
To trace how the blood flows throughout the body and the role of the heart in the planning stages, it happens through:
1. After that the body consumes oxygen in the blood, the blood rushes to the right atrium of the heart of the portal vein upper and lower portal vein.
2.
3.
4. In the lungs are loaded blood oxygen we breathe.
5. Oxygen-rich blood flows from the lungs to the left atrium.
6.
7. The left ventricle contracts to pump blood through the aortic valve (AORTIC VALVE) to parts of the body through the largest artery in the body which is the aorta.
8. In the body, take the tissues and organs of oxygen and nutrients loaded in the blood.
9. Finally, the blood returns to the right atrium, and begin circulation again.
It is important to note that the contractions of the heart chambers are jointly and according to a regular pattern. So that in the start The Alovenan contracts together, and then contracts the ventricles together, and stage these contractions result in pumping blood to the body through the arteries, and blood flow in the arteries as intermittent pumping system is what gives us the impulses we feel when we press lightly on the artery. And speed the natural heartbeat at rest usually range between 60 and 100 beats per minute.
The contraction of the muscles of the heart chambers, and thus to pump blood to the body, gets due to activate the muscles of the heart an electric current with a weak force. This stems electricity from somewhere within the heart called the sinus node is located in the right atrium. When issued sinus node splash of power, gets contraction of the atria and thus pump their blood into the ventricles. Then moves on electricity, via fiber-like electrical wiring, to another area between the atria and the ventricles called atrial node - ventricular. And passed an electric current to pass to the ventricles and cause Anaqbadhma, and thus their blood pumping.
And vary the speed of the heartbeat from one person to another through physical activity or during rest. This difference is normal if you do not cause a significant decrease in blood pressure due to increase or decrease the speed of the heart beat. Rapid economic blood generated by the contractions of the heart. Can for the heart to pump blood at 150 beats a minute to instances of physical stress or emotional. And can slow down to 50 beats per minute at rest.
After this, we can understand why heartbeat disorders arise, and there are different reasons for heart rhythm disorders, may occur:
* If sinus node fails to generate sufficient heartbeat.
* If sinus node systems become abnormal.
* If captured elsewhere in the atrium and sinus node function and instead issued a voltage.
* If you get disability or interruption in the process of the passage of electrical current through the electrical wiring network deployed in the heart, which can lead to various forms of unrest in pulse contraction of the ventricles independently of the atria.
* If Alovenan lost the ability to contract effectively, and thus got atrial fibrillation.
* The worst cases of cardiac arrhythmia, when the ventricles lose the ability to contract effectively, and this leads to a condition called ventricular fibrillation. In ventricular fibrillation the heart is unable to pump blood, and the patient dies within a short time. The ventricular fibrillation is the most common cause of sudden death cases.
