Larly. Atrial fibrillation and atrial flutter are common cardiac arrhythmias, which lead to an irregular and sometimes rapid heart rate. These atrial arrhythmias may interfere with the heart's ability to pump blood properly from its upper chambers (atria). The atria may not always empty completely, and blood remaining there too long may stagnate and potentially clot. Such clots may travel to other parts of the body, where they may cause blockages in the blood supply to the limbs, brain or heart. In ventricular fibrillation, the lower chambers of the heart (ventricles) quiver feebly instead of contracting powerfully. This is the most severe type of arrhythmia, causing death in minutes unless medical assistance is obtained immediately.

It is the most common arrhythmia in young adults, and most cases are curable with ablation. Ventricular tachycardia is rapid beating that originates in the heart's lower chambers and is often caused by heart disease. This serious condition can lead to sudden cardiac arrest and requires immediate treatment. Sinus node dysfunction is caused by damage to the heart's natural pacemaker, causing the heart to beat slowly and not increase correctly during exercise. Complete atrioventricular (heart) block occurs when the electrical signal necessary for heart beat to occur does not move properly from the upper to lower chambers.
