Cardiac arrhythmia

Arrhythmia of the heart - what to do when a cardiac arrhythmia

It happens that the heart begins to beat “wrong” is too slow or too fast, or the strokes follow each other through different periods of time, and then suddenly appears extraordinary, “extra” reductions, or, on the contrary, pause, “fallout”. In medicine such States are called arrhythmias. They appear due to the problems in the conduction system of the heart, providing regular and coordinated contraction of the cardiac muscle. Another group of diseases of this system is the heart block.

Many blockages exist unbeknownst to the patient, but often indicate the presence of another disease of the heart. The most severe blockade appear rhythm and contractility of the heart. Often these diseases lead to dysfunction of the heart or the development of serious complications from other agencies. In turn, they can be a complication of other serious diseases.

Statistics of heart disease and mortality shows that cardiac arrhythmias as a cause of death is around 10-15 percent of all heart disease. Therefore, for the study, diagnosis and treatment of arrhythmias, there is a special section of cardiology – arterial hypertension.

What is a cardiac arrhythmia?

Causes and symptoms of cardiac arrhythmiaDuring each heartbeat is consistent with the reduction of its departments – first the Atria and then the ventricles. Cuts follow each other at equal intervals of time. Arrhythmia called violations of frequency, rhythm and sequence of contractions of the heart. Statistics heart disease and mortality shows that cardiac arrhythmias as a cause of death is around 10-15 percent of all heart disease.

Causes of cardiac arrhythmia?

In a healthy person, to provoke the arrhythmia can be strong emotional arousal, abundant food, constipation, tight clothing, insect bites, alcohol, coffee, certain medications, stress. High risk of arrhythmia in people with diabetes, especially if it is combined with obesity and high blood pressure. Arrhythmias can occur and the more innocuous reasons: for example, premenstrual syndrome in women is often accompanied by arrhythmia, pain in the heart, a feeling of suffocation.

Arrhythmia can occur as a result of injuries or disorders of the heart, to be a complication of cardiac surgery and may be a symptom of a number of diseases, such as:
-heart diseases, heart failure, ischemic heart disease,
-mitral valve prolapse,
-thyroid disease and other hormonal disorders.

Predisposition to aritmie can be inherited.

What happens when arrhythmia?

Correct heart rhythm is provided by a special conducting system of the heart. It consists of specialized cells that generate and conduct electrical impulses, guiding the coordinated contraction of the heart muscle.

The pulse that triggers the contraction of the heart, is produced in the upper part of the right atrium called the sinoatrial node (pacemaker). This node is responsible for the fact that the heart contracts with a frequency of 60-80 beats per minute. Then the signal is delivered to the Atria, causing them to fall, then to the ventricles. Since any cell conduction system has electrical activity, in some cases, the pulses from different departments conducting system prevail over impulses from the sinus node. In other cases, one pulse may cause a few heartbeats, or, conversely, not every impulse leads to the reduction. All this leads to various kinds of heart rhythm disturbance.
