- W2100069431 abstract "The protective effect of antiarrhythmic agents for patients with malignant ventricular arrhythmia (defined as noninfarction ventricular fibrillation or sustained hemodynamically compromising ventricular tachycardia) remains uncertain. We have analyzed survival among 123 such patients (98 males, 25 females, average age 53.6 years) dependent on the abolition of antiarrhythmic drugs of salvos of ventricular tachycardia and R-on-T ventricular premature beats (Lown grades 4B and 5). Over an average follow-up of 29.6 months there were 35 deaths (11.2 percent annual mortality rate) of whom 23 patients succumbed suddenly (8.2 percent annual mortality rate). Among 98 patients in whom antiarrhythmic drugs abolished grades 4B and 5 ventricular premature beats, only 6 sudden deaths occurred for a 2.3 percent annual mortality rate. Of the 25 patients in whom advanced ventricular premature beats were not controlled, 17 died suddenly. Seventy-nine patients had left ventricular studies suitable for analysis. Among 44 patients with left ventricular dysfunction, control of ventricular premature beats was a critical element predicting survival. The annual sudden death rate for the 12 noncontrolled patients with left ventricular dysfunction was 41 percent contrasting with only 3.1 percent for the 32 patients with similar abnormalities in ventricular function in whom advanced ventricular premature beats were abolished. It is concluded that antiarrhythmic drugs can protect against the recurrence of life-threatening arrhythmias in patients who have manifest ventricular fibrillation or ventricular tachycardia and that abolition of certain advanced grades of ventricular premature beats provides an effective therapeutic objective." @default.
