Ventricular tachycardia (V-tach or VT) is a cardiovascular disorder in which fast heart rate occurs in the ventricles of the heart. [3] Although a few seconds of VT may not result in permanent problems, longer periods are dangerous; and multiple episodes over a short period of time are referred to as an electrical storm.
An automated external defibrillator or automatic electronic defibrillator (AED) is a portable electronic device that automatically diagnoses the life-threatening cardiac arrhythmias of ventricular fibrillation (VF) and pulseless ventricular tachycardia, [1] and is able to treat them through defibrillation, the application of electricity which stops the arrhythmia, allowing the heart to re ...
Ventricular tachycardia (VT or V-tach) is a potentially life-threatening cardiac arrhythmia that originates in the ventricles. It is usually a regular, wide complex tachycardia with a rate between 120 and 250 beats per minute.
A ventricular assist device (VAD) is an electromechanical device that provides support for cardiac pump function, which is used either to partially or to completely replace the function of a failing heart.
Most of these rhythm disturbances consisted of single PVCs and were clinically insignificant. However, one crewmember experienced a 5-beat run of ventricular tachycardia during a lower-body negative pressure protocol, and another had periods of “wandering supraventricular pacemaker” during rest and following exercise.
Torsades de pointes – A type of ventricular tachycardia with a characteristic ECG appearance that can progress to ventricular fibrillation. Ventricular fibrillation (vfib) – Fibrillation of the ventricles is a life-threatening arrhythmia and should be treated by defibrillation and is a medical emergency. Vfib results from uncoordinated ...
The first total repair of tetralogy of Fallot was done by a team led by C. Walton Lillehei at the University of Minnesota in 1954 on an 11-year-old boy. [85] Total repair on infants has had success from 1981, with research indicating that it has a comparatively low mortality rate. [ 72 ]
Boxer cardiomyopathy shares striking similarities to a human myocardial disease called arrhythmogenic right ventricular cardiomyopathy (ARVC). [1] On histopathology, the disease is characterized by the progressive replacement of ventricular myocardium (primarily right ventricular myocardium) with fatty or fibro-fatty tissue. [2]
