Ventricular fibrillation masquerading as ventricular standstill
Critical Care Medicine, 1981After the induction of ventricular fibrillation (VF) in 29 animals, ECGs were serially recorded to determine whether a very low amplitude or a straight line ECG could occur in some leads while coarse fibrillatory waves were present in the other leads. Ventricular fibrillation was electrically induced via a transvenous catheter electrode advanced into ...

Ventricular Tachycardia with Congenital Ventricular Diverticulum
Chest, 1991A 24-year-old man presented with symptomatic, recurrent, sustained ventricular tachycardia (VT). He was found to have a basal inferior left ventricular diverticulum. His sustained VT was reproduced by programmed electrical stimulation and was unresponsive to procainamide, tocainide, propafenone, and flecainide. Endocardial mapping followed by resection

Ventricular tachyarrhythmias: Ventricular tachycardia and ventricular fibrillation
2018Ventricular tachyarrhythmias are abnormal patterns of electrical activity arising from the ventricular tissue (myocardium and conduction tissue). Ventricular tachycardia (VT) is an abnormal rapid heart rhythm originating from the ventricles. The rhythm may arise from the ventricular myocardium and/or from the distal conduction system.

Ventricular Strain and Ventricular Hypertrophy
New England Journal of Medicine, 1949WHEN medical terminology was less precise the expression "strained heart" was employed at times to describe obscurely but ominously diseased hearts.

Ventricular safety pacing, ventricular sense response, and ventricular tachycardia
Heart Rhythm, 2010The ventricular sense response (VSR) algorithm enforces biventricular pacing on ventricular sensing to maximize biventricular pacing in patients with atrial fibrillation. This report describes a case of recurrent ventricular tachycardia that may be facilitated by this enforced pacing algorithm.

Child's Nervous System, 2003
Ventricular dilatation is generally defined on ultrasounds (US) or MRI as an atrium larger than 10 to 12 mm on axial or coronal planes. After 22 weeks, this measure is independent of the term.In the view of the prognostication, it is of utmost importance to not only calculate the width of the ventricles but also to estimate the progression of the ...

Early premature ventricular beats, repetitive ventricular response, and ventricular fibrillation
American Heart Journal, 1967Abstract Three cases are reported in which early premature ventricular beats were followed by ventricular fibrillation (2 cases) and repetitive ventricular responses (1 case). The relationship of these findings to the vulnerable phase is discussed.

Left ventricular involvement in right ventricular dysplasia
American Heart Journal, 1992Right ventricular dysplasia, a heart muscle disease of unknown cause, anatomically characterized by variable replacement of myocardial muscle with adipose or fibroadipose tissue, is usually considered a selective disorder of the right ventricle. However, concomitant left ventricular involvement has been noted in a few cases.

Left Ventricular Volumes with Ventricular Inhibited and Atrial Triggered Ventricular Pacing
Acta Medica Scandinavica, 1983ABSTRACT Left ventricular (LV) volumes were assessed with equilibrium radionuclide angiocardiography at rest and during exercise in nine patients with high‐degree AV block treated with ventricular inhibited pacing (VVI), which was subsequently changed to atrial triggered ventricular pacing (VAT). The ventricular rates were similar at rest but higher on

Medical Clinics of North America, 2019
Ventricular tachycardia is commonly seen in medical practice. It may be completely benign or portend high risk for sudden cardiac death. Therefore, it is important that clinicians be familiar with and able to promptly recognize and manage ventricular tachycardia when confronted with it clinically. In many cases, curative therapy for a given ventricular
