Thrombolytic therapy salvages ischemic myocardium by rapidly reestablishing coronary artery patency in acute myocardial infarction. One of its major limitations is the complication of hemorrhage. A retrospective study of myocardial infarction patient

The incidence and clinical predictors of amiodarone pulmonary toxicity were examined in 573 patients treated with amiodarone for recurrent ventricular (456 patients) or supraventricular (117 patients) tachyarrhythmias. Amiodarone pulmonary toxicity w

Between 1977 and 1986, 589 patients (age, 57 +/- 13 years; 464 men and 125 women) received amiodarone for ventricular fibrillation (VF; 147 patients), sustained (VT-S; 242 patients) or nonsustained (VT-NS; 80 patients) ventricular tachycardia, or sup

The site of ventricular stimulation is an important variable in the initiation of ventricular tachycardia (VT) by programmed ventricular stimulation. Among 169 patients studied consecutively, 17 (10%) had ventricular tachycardia induced by programmed

We assessed the value of clinical electrophysiologic study using intracardiac recording and programed electrical stimulation in 34 patients who had unexplained syncope and/or presyncope. All patients had normal electrocardiograms, and no abnormality

Induction of ventricular tachycardia (VT) at electrophysiologic study in patients taking amiodarone poorly predicts recurrence of VT. Consequently, a discriminant function was developed (using parameters based on retrospective data) that appeared to

The syndrome of enhanced atrioventricular nodal (AVN) conduction has been defined arbitrarily by: AH interval during normal sinus rhythm (AH-NSR) less than or equal to 60 msec; shortest right atrial pacing cycle length (PCL) maintaining 1:1 AVN condu

The advantages and disadvantages of pacing and transvenous cardioversion in terminating episodes of tachyarrhythmias are examined.

We followed 11 patients for 5 to 27 months (mean 14.9) after implantation of a permanent transvenous low-energy synchronized cardioverter to evaluate both long-term reproducibility of ventricular tachycardia (VT) induction via noninvasive programmed

Using standard microelectrode techniques, the cellular electrophysiologic features of ventricular myocardium resected from 8 patients with refractory arrhythmias were studied in vitro. Action potentials from damaged myocardium compared with normal my
