Focal mechanisms underlying ventricular tachycardia during prolonged ischemic cardiomyopathy.
BACKGROUND The present study was performed to define the mechanisms underlying spontaneously occurring ventricular arrhythmias in the failing heart. METHODS AND RESULTS Three-dimensional cardiac mapping from as many as 232 intramural sites was performed in five dogs with ischemic cardiomyopathy induced by multiple intracoronary embolizations. After 5 to 10 weekly embolizations with 90-microns...
متن کاملReentrant and focal mechanisms underlying ventricular tachycardia in the human heart.
BACKGROUND To determine the mechanisms of ventricular tachycardia (VT) in humans, three-dimensional intraoperative mapping of up to 156 intramural sites was performed in 13 patients with healed myocardial infarction and refractory VT. METHODS AND RESULTS Mapping was of sufficient density to define the mechanism of 10 VTs in eight patients. In five of 10 cases, sustained VT was initiated in th...

SUZUKI, K. Clinical Features of Sustained Ventricular Tachycardia among Various Underlying Heart Diseases. Tohoku J. Exp. Med., 1990, 162 (1), 15-26 Clinical findings of 52 patients with sustained ventricular tachycardia (VT) were analyzed to assess the importance of the underlying etiology. Among patients with organic heart diseases, no differnces were found in the VT rate, the incidence of sy...
متن کاملAblation of Ventricular Tachycardia in Patients with Ischemic Cardiomyopathy.
Ventricular tachycardias (VTs) occurring after prior myocardial infarction are usually caused by reentrant circuits formed by surviving myocardial bundles. Although part of the reentrant circuits may be located in the midmyocardium or epicardium, most of the VTs can be safely and successfully ablated by endocardial ablation targeting the late potentials/local abnormal ventricular activation, wh...
متن کاملBidirectional ventricular tachycardia in ischemic cardiomyopathy during ablation
Case report A 78-year-old man presented with recurrent appropriate shocks from his implantable cardioverter-defibrillator (ICD) for monomorphic VT. He was known to have ischemic cardiomyopathy and monomorphic VT for which he had received an ICD 12 years ago. Since then, he had infrequent episodes of VT while taking sotalol that were terminated with antitachycardia pacing. He presented with VT s...
