Supraventricular Extrasystoles Supraventricular Extrasystoles - ECG Supraventricular extrasystole (SVES) is one of the most common abnormalities that is found in ECGs. The problem is caused by sinoatrial (SA) node itself or by other location in heart atria. The problem is premature emission of electric impulse that spreads throughout the atria and then it is transmitted to the ventricles.
A ventricular premature beat is an extra heartbeat caused by an abnormal electrical impulse starting in the lower chambers of the heart (the ventricles) before a normal heartbeat would occur. It is also known as a ventricular ectopic beat or a premature ventricular contraction.This is a form of arrhythmia that is similar to an atrial ectopic heartbeat. But where that affects the upper chambers of the heart (the atria), this affects the ventricles (or lower chambers of the heart). ventricular premature beat is an extra heartbeat caused by an abnormal electrical impulse starting in the lower chambers of the heart (the ventricles) before a normal heartbeat would occur. It is also known as a ventricular ectopic beat or a premature ventricular contraction.
