Clinical characteristics that correlate with arrhythmia inducibility were determined in 150 consecutive survivors of cardiac arrest. All underwent electrophysiologic study with a uniform protocol when they were not receiving antiarrhythmic drugs. A ventricular tachyarrhythmia (sustained monomorphic ventricular tachycardia, ventricular fibrillation or nonsustained ventricular tachycardia) was in...

pressure. Ventricular tachycardia was produced by repeated injections of deslanoside (25 ,g/kg) at 15 min intervals. Only one of eight animals showed conversion of ventricular tachycardia to sinus rhythm with bretylium administration (2-100 mg/kg i.v.). In each animal, bretylium increased the ventricular rate. The effect of bretylium (30 mg/kg i.v.) on duration of ventricular tachycardia induce...

The occurrence in 6 patients of premature ventricular beats before reversion to sinus rhythm, after the intravenous administration ofverapamil-for the treatment of supraventricular tachycardia, is reported. Four patients had pre-excitation syndromes (Wolff-Parkinson-White in I and Lown-Ganong-Levine in 3) and one patient had bradycardia-tachycardia syndrome. In the remaining patient, at previou...

A microcomputer algorithm for tachycardia identification, suitable for use in an implanted antitachycardia pacemaker, is described. The system employs an atrial and ventricular electrogram, detects a sustained fast rate in either chamber, and awakens the main program to perform detailed analysis of the tachycardia and its immediately preceding beats. The algorithm distinguishes atrial, ventricu...

We describe 3 patients with ventricular tachycardia in whom epicardial ablation was done after prior attempts of endocardial ablation had failed. Clinical ventricular tachycardia originated at the right ventricular outflow tract in one patient and near the mitral annulus in another patient. In these two cases ventricular tachycardia was mapped and successfully ablated with a percutaneous subxip...

Patients with an implantable cardioverterdefibrillator (ICD) may receive frequent shocks or antitachycardia pacing for monomorphic ventricular tachycardia despite suppressive drug therapy. Antitachycardia pacing is often well-tolerated but not always effective. High voltage cardioversion is usually painful and may cause severe, disabling anxiety for some patients. Therefore, catheter ablation i...

INTRODUCTION Bilateral coronary artery fistulae to pulmonary artery with ventricular tachycardia have not yet been described in the literature. CASE OUTLINE A case of a 23-year-old male patient who was treated at our clinic for recurrent ventricular tachycardia is presented. The patient was born with six fingers on his left hand, which was surgically corrected in his early childhood. Perfusio...
