Large Infarct Induce Ventricular Tachycardia
Background. Previous studies have demonstrated that both ventricular tachycardia (VT) and ventricular fibrillation (VF) may begin as figure-eight reentry: VT with a longer cycle length from spared tissue adjacent to an infarct by programmed stimulation and VF with a shorter cycle length from noninfarcted tissue by a large premature S2 stimulus. These results suggest that the type of tissue or c...

متن کاملMyocardial infarct size and ventricular function in rats.
To define the relationship between infarct size and ventricular performance, we performed hemodynamic studies in rats 21 days after left coronary artery occlusion. Ventricular performance was assessed under ether anesthesia by measurements of baseline hemodynamics and stressed performance as determined by the peak cardiac output and stroke volume obtained during intravenous volume loading and b...
متن کاملPATHOPHYSIOLOGY AND NATURAL HISTORY VENTRICULAR Quantitative analysis of myocardial infarct structure in patients with ventricular tachycardia
To study whether myocardial infarction differs in patients with and without ventricular tachycardia, the hearts of 22 deceased patients with ventricular tachycardia and 21 deceased control patients were analyzed quantitatively. The hearts from the ventricular tachycardia group were heavier and more dilated than those from the control group. Histologic analysis of a representative cross section ...
متن کاملTHERAPY AND PREVENTION Beneficial effects of timolol on infarct size and late ventricular tachycardia in patients with acute myocardial infarction
This investigation was undertaken to study the effects of 8-adrenergic blockade with timolol on infarct size and on the incidence of late ventricular tachycardia in patients with acute myocardial infarction of less than 6 hr of evolution. Patients were assigned randomly either to a placebo-treated group (98 patients) or to a timolol-treated group (102 patients). The patients were treated with 5...
