Premature extrastimulus pace-mapping to identify the origin of ventricular premature depolarizations☆
Introduction Frequent premature ventricular depolarizations (VPDs) may lead to the development of dilated cardiomyopathy, which is reversible with catheter ablation. Closely coupled VPDs have also been shown to trigger polymorphic ventricular tachycardia. Twelve-lead electrocardiogram morphology and pace-mapping are useful clinical tools for localization of the site of origin of VPDs, particula...
متن کاملFunctional Pace-Mapping Responses for Identification of Targets for Catheter Ablation of Scar-Mediated Ventricular Tachycardia
Background—Myocardial scars harbor areas of slow conduction and display abnormal electrograms. Pace-mapping at these sites can generate a 12-lead ECG morphological match to a targeted ventricular tachycardia (VT), and in some instances, multiple exit morphologies can result. At times, this can also result in the initiation of VT, termed pace-mapped induction (PMI). We hypothesized that in patie...
متن کاملMapping and ablation of frequent post-infarction premature ventricular complexes.
INTRODUCTION Premature ventricular complexes (PVCs) occur frequently in patients with heart disease. The sites of origin of PVCs in patients with prior myocardial infarction and the response to catheter ablation have not been systematically assessed. METHODS AND RESULTS In 28 consecutive patients (24 men, age 60 ± 10, ejection fraction [EF] 0.37 ± 0.14) with remote myocardial infarction refer...
متن کاملprevention of atrioventricular block during radiofrequency ablation by pace mapping of koch’s triangle
background: complete atrioventricular block (av block) is a serious complication of slow pathway ablation therapy in the treatment of atrioventricular nodal re-entrant tachycardia (avnrt). the present study was aimed at determining whether the electroanatomical pace mapping of koch’s triangle could significantly improve the safety, efficiency, and efficacy of selective slow pathway ablation i...
متن کاملMapping and ablation of idiopathic ventricular fibrillation.
BACKGROUND Ventricular fibrillation is the main mechanism of sudden cardiac death. The feasibility of eliminating recurrent episodes by catheter ablation has not been reported. METHODS AND RESULTS Twenty-seven patients without known heart disease (13 men, 14 women, 41+/-14 years of age) were studied after being resuscitated from recurrent (10+/-12) episodes of primary idiopathic ventricular f...
