Measurements were made in 12 normal subjects and during induction of sustained ventricular tachyarrhythmias in 31 patients with remote myocardial infarction. QT interval measurements were made semiautomatically with computer assistance and the total QT interval was divided into early (QT1) and late (QT2) components. QT intervals and QT interval dis...

Intracoronary arterial occlusion: a novel technique potentially useful for ablation of cardiac arrhythmias.
Published in Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing
To develop a new technique for ablating arrhythmias by interrupting coronary perfusion of the myocardium, we studied six mongrel dogs, weighing 20-35 kg. Under angiographic guidance a microcatheter (1.0 mm diameter) was introduced into a branch of the left anterior descending or posterior descending coronary artery. A detachable platinum coil (0.02...
Evaluation of a programming algorithm for the third tachycardia zone in a fourth-generation implantable cardioverter-def...
Published in Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing
The clinical efficacy of electrical algorithms for termination of slow ventricular tachycardia (VT) and ventricular fibrillation (VF) in implantable cardioverter-defibrillators (ICDs) is well established. Such algorithms have not been equally well defined for fast VT reversion. We report the testing of a prospectively designed algorithm for ICDs to...
Arrhythmogenic right ventricular dysplasia: clinical results with implantable cardioverter defibrillators.
Published in Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing
Arrhythmogenic right ventricular dysplasia is a clinical entity characterized by fatty infiltration of the right ventricle and left bundle morphology ventricular tachycardia occurring in young patients. The most common cause of death is tachyarrhythmic. Pharmacological and nonpharmacological therapies, including implantable cardioverter defibrillat...
Ultrarapid train stimulation versus conventional programmed electrical stimulation for induction of ventricular arrhythm...
Published in Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing
Conventional programmed electrical stimulation (PES) of the ventricle is useful for establishing inducibility or noninducibility of clinical ventricular arrhythmias (VA) but is complex and time consuming. The present study was designed to compare a standard PES protocol with an alternative method using ultrarapid train stimulation in patients with ...
Dose and rate-dependent effects of adenosine on atrial action potential duration in humans.
Published in Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing
Adenosine provokes atrial fibrillation (AF) in some patients with paroxysmal supraventricular tachycardia (PSVT). Which patients are more susceptible to develop atrial fibrillation after the administration of adenosine to terminate PSVT is unknown. We prospectively measured atrial action potential duration (APD) at incremental doses of 3, 6, and 12...
Pulsing microwave energy: a method to create more uniform myocardial temperature gradients.
Published in Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing
Microwave energy has been proposed as a possible technique to create large myocardial lesions. Achieving a uniform myocardial temperature gradient during microwave ablation may prevent excessive endocardial temperatures while maintaining temperatures at depth. The goal of the current study was to examine the ability of microwave (MW) pulsing to ach...
