Understanding Different Types of Arrhythmia


There are many different types of arrhythmias or rhythmic disorders of the heart. arrhythmias are characterized by rhythmic disturbances in the heart’s electrical activity or conduction of electrical signals within the body. arrhythmias may occur in any one or several parts of the heart, but most commonly they occur in the left ventricle, which is a pump organ located within the heart. arrhythmias are commonly seen in people of all ages, although more common in elder age. They can affect anyone; it is not uncommon for someone to have arrhythmias once in their lifetime.

Why Need to know about Arrhythmia

The most common type of arrhythmias is atrial fibrillation (AF), which occurs when the ventricular muscles contract in response to a stimulus from the atria. This stimulation causes the ventricular muscles to extend into the atrium, filling the cavity with blood. Because of this action, the heart does not receive normal electrical impulses from the atria, or atrial muscles. Because the atria are so active during resting heart rate (routinely pathing the ventricular muscle over the muscle at rest), and because the ventricular cavity is so full, it can be very difficult to maintain a normal heart rate and circulate the blood effectively. When someone with atrial fibrillation experiences mild symptoms such as dizziness, pounding, irregular heartbeat, sweating, nausea, or palpitations, they should be seen by a physician to ensure that there is no serious medical problem.

Two other types of arrhythmias are congenital heart disease, or CMD, and temporal arteriovenous malformations, or TAVM. congenital heart disease is a condition where congenital heart defects cause the heart to beat at an abnormal rate. TAVM is a type of arrhythmias where the ventricular muscle does not relax during cardiac activity or does not contract completely, or in some instances does not contract at all. While TAVM can be life-threatening, it is usually temporary, occurring in only a few percent of cases. CMD is a condition where the heart fails to beat at its own beat, or an individual develops ventricular fibrillation after suffering a heart attack.
