WebSummary Ventricular tachycardia (VT) is a potentially life-threatening arrhythmia originating in the cardiac ventricles. VT usually results from underlying cardiac diseases, such as myocardial infarction or cardiomyopathy , but it can also be idiopathic or caused by drugs and electrolyte imbalances. Clinical manifestations range from palpitations WebDefinition. The term supraventricular tachycardia (SVT) refers to any tachydysrhythmia arising from above the level of the Bundle of His, and encompasses regular atrial, irregular atrial, and regular atrioventricular tachycardias. It is often used synonymously with AV nodal re-entry tachycardia (AVNRT), a form of SVT. great schools.org fl https://paradiseusafashion.com
