Ventricular fibrillation is often a fatal arrhythmia. It occurs when the ventricular rate exceeds 400. In this setting, virtually no forward cardiac output occurs. Advanced Cardiac Life Support ...

This paradoxical increase in ventricular heart rates may lead to ventricular fibrillation (ventricular rates of 400 to 600 bpm) and death. Procainamide or urgent electrical cardioversion is ...

and ventricular fibrillation. Heart problems associated with strokes may be caused by the same underlying process that produced the stroke, most commonly thrombosis (blockage) of an artery.

Patients with structural heart disease are at risk for life ... VT can degenerate to ventricular fibrillation as ischemia and hypotension develop, particularly in patients with impaired ...

Atrial fibrillation (AF) and chronic heart failure (CHF ... options for prevention of AF in patients with ventricular dysfunction. In conclusion, AF is associated with increased mortality in ...

2 Studies have shown that endurance athletes may exhibit a higher incidence of bradyarrhythmias and atrial fibrillation, while the association between physical training and ventricular arrhythmias ...

Amiodarone effectively maintains sinus rhythm in patients with atrial fibrillation ... for patients with substantial left ventricular hypertrophy or heart failure. This treatment approach is ...

The researchers found that just six weeks of anabolic steroid use can harm the way cells in the heart work together. The steroids weaken the cell connections and reduce the function of sodium channels ...

Novartis AG has synthesized new sodium channel protein type 5 subunit alpha (SCN5A; Nav1.5) blockers reported to be useful for the treatment of heart failure, long QT syndrome, hypertrophic ...
