The heart has its own unique self-conducting electrical system, which enables the heart to beat. It originates in the right atrium, one of the upper chambers of the heart. Tachycardia is a term used to describe an abnormally fast heart rate. Ventricular Tachycardia occurs when there is a di...
Ventriculartachycardia. An example of an extraordinarily fastventricular tachycardia, with a heart rate of almost 300 BPM. (Courtesy of CDR Jonathan T.

Tachycardia itself is a heart rate that exceeds the normal range, generally a heart rate of over 100 beats per minutes. A Tachycardia can be caused by a number of factors which are usually benign. But some types of tachycardia, like ventricular tachycardia, can be dangerous due the speed ...
ventricular tachycardia A dangerous disorder of heart rhythm in which the contraction of the lower main pumping chambers is initiated from uncontrolled electrical impulses arising in the ventricles instead of in the SINOATRIAL NODE. The heart rate is abnormally fast-between 140 and 220 beats per minut...
1. Ventricular tachycardia This ECG shows a wide-complex tachycardia in a right bundle branch block pattern going quite fast (heart rate about 150 BPM). Note the morphology of the QRS complex in lead V6. There is a RS complex in this lead which is one of the morphology criteria to estab...
QRS complexeswith abnormal morphology, with increased length, have the aspect of right bundle branch block, if the ventricular tachycardia has the origin from the left ventricle or left bundle branch block aspect if ventricular tachycardia has the origin on the right ventricle. Heart rate is 140-...
Ventricular Tachycardia (VT) ECG Review Ventricular tachycardia refers to a wide QRS complex heart rhythm — that is, a QRS duration beyond 120 milliseconds — originating in the ventricles at a rate of greater than 100 beats per minute. ...

Catecholaminergic Polymorphic Ventricular Tachycardia is a rare ion channelopathy characterized by polymorphic ventricular tachycardia during exercise despite a structurally normal heart. Untreated, it has a high risk of sudden death, and delays in clinical diagnosis are common, as t...
