متن کاملTrigger elimination of polymorphic ventricular tachycardia and ventricular fibrillation by catheter ablation: trigger and substrate modification
Ventricular fibrillation (VF) is a malignant arrhythmia, usually initiated by a ventricular premature contraction (VPC) during the vulnerable period of cardiac repolarization. Ablation therapy for VF has been described and increasingly reported. Targets for VF triggers are VPCs preceded by Purkinje potentials or from the right ventricular outflow tract (RVOT) in structurally normal hearts, and ...
متن کاملPapillary Muscle Ventricular Tachycardia Masquerading as Bidirectional Ventricular Tachycardia
Introduction: Bidirectional ventricular tachycardia (VT) is a rare type of VT that appears in digoxin toxicity and young patients with catecholaminergic polymorphic VT (CPVT). The occurrence of bidirectional VT originating from the papillary muscle has not been reported in the literature. Case Presentation: A 38-year-old female presented with long standing palpitation lasting several months. Pa...
متن کاملPremature ventricular complexes as a trigger for ventricular fibrillation.
INTRODUCTION AND OBJECTIVES The mechanisms that trigger ventricular fibrillation (VF) are poorly understood. The aim of this study was to analyze the initiation of VF in electrograms stored in implantable cardioverter-defibrillators (ICDs). METHODS We analyzed ICD electrograms from patients who had suffered at least one episode of VF. RESULTS Of 250 patients with ICDs, 13 (10 male and 3 fem...
متن کاملIschemic Ventricular Tachycardia Presenting as a Narrow Complex Tachycardia
This report describes a patient presenting with a narrow complex tachycardia in the context of prior myocardial infarction and impaired ventricular function. Electrophysiological studies confirmed ventricular tachycardia and activation and entrainment mapping demonstrated a critical isthmus within an area of scar involving the His-Purkinje system accounting for the narrow QRS morphology. This v...
