The proarrhythmic effects of class IA antiarrhythmic drugs were prospectively evaluated during programmed ventricular stimulation in 24 consecutive patients with frequent ventricular premature beats whose baseline study, performed while no antiarrhythmic drugs were being taken, showed no inducible sustained ventricular arrhythmias. No patient had(More)
To determine temporal evolution of sustained ventricular arrhythmias inducible after acute myocardial infarction (AMI), serial programmed ventricular stimulation (PVS) was performed in 27 patients 15 +/- 4 and 150 +/- 28 days after AMI. These patients did not have worsening of congestive heart failure or angina, coronary artery bypass surgery or spontaneous(More)
The clinical importance of myocardial ischemia without associated symptoms in patients with atherosclerotic coronary disease has not been clarified. We present three patients in whom painless cardiac ischemia was associated with the induction of cardiac arrest and/or ventricular tachycardia/fibrillation. In the two surviving patients, programmed ventricular(More)
In this study, 16 patients matched with 16 controls were hypnotized prior to angioplasty. The hypnotized patients had a 25% increase in the time the cardiologist was able to keep the balloon inflated compared to the controls. Of the hypnotized patients, 13% required additional narcotic pain medication during the procedure as compared to 44% for the(More)
Electrophysiologic studies were performed in nine survivors of out-of-hospital cardiac arrest who had no overt heart disease on clinical, hemodynamic and angiographic evaluation. Cardiac arrest occurred during sedentary activity in seven patients and during exercise in two; no patient was on antiarrhythmic drugs at the time of cardiac arrest. Twenty-four(More)
The prognostic significance of the response to programmed ventricular stimulation was studied in 75 stable survivors of acute myocardial infarction. Programmed ventricular stimulation induced sustained ventricular arrhythmias in 33 (44%) patients and did not induce these arrhythmias in 42 (56%) patients. During a mean follow up of 18 months, four patients(More)
A 59-year old female with history of benign ventricular ectopy who developed sustained monomorphic ventricular tachycardia (VT) during therapy with procainamide is reported. The tachycardia occurred 24 hours after institution of procainamide without any other evidence of drug toxicity or QT prolongation. When procainamide was withheld, VT resolved(More)
