Abstract In this study, the inverse solution with a single dipole was computed to localize premature ventricular contraction (PVC) origin from long term multiple leads ECG measurements on fourteen patients. The stability of obtained results studied respect preprocessing signals used as an input and complexity torso model. Two methods were for baseline drift removal. After averaging heartbeats, ...

Aim: This work investigates the correlation between the cardiac electrical activity underlying spontaneous ventricular tachyarrhythmias and their modes of onset. Signals: We analyzed 81 episodes of spontaneous ventricular tachycardia (VT) and ventricular fibrillation (VF) lasting at least 5 seconds from 17 patients. The cardiologist classified VT/VF malignancy by considering fast VT as more mal...

Introduction Ventricular fibrillation (VF) triggered by premature ventricular contraction (PVC) most frequently originates from the His-Purkinje system and right ventricular outflow tract (RVOT) in patients with idiopathic VF. Radiofrequency catheter ablation (RFCA) of triggering PVCs is reportedly useful for the successful elimination of VF. The diagnosis of early repolarization (ER) syndrome ...

In order to determine the role of the coupling interval of a premature ventricular contraction (PVC) in the development of paroxysmal ventricular tachycardia (PVT) during the early phase of acute myocardial infarction in man, 52 male patients with documented acute myocardial infarction had 24-hour Holter monitoring commenced within 24 hours of the onset of prolonged chest pain. Review of the ta...
