متن کاملRelevant ventricular septal defect caused by steam pop during ablation of premature ventricular contraction.
A 62-year-old female patient with highly symptomatic, idiopathic, monomorphic, premature ventricular contraction presented at our institution for further treatment (Figure 1A). Previous medical antiarrhythmic treatment has failed. She had a history of mitral valve repair attributable to rheumatic heart disease 2 years before and paroxysmal atrial fibrillation. Aside from that, transthoracic ech...
متن کاملEpicardial phrenic nerve displacement during catheter ablation of atrial and ventricular arrhythmias: procedural experience and outcomes.
BACKGROUND Arrhythmia origin in close proximity to the phrenic nerve (PN) can hinder successful catheter ablation. We describe our approach with epicardial PN displacement in such instances. METHODS AND RESULTS PN displacement via percutaneous pericardial access was attempted in 13 patients (age 49±16 years, 9 females) with either atrial tachycardia (6 patients) or atrial fibrillation trigger...
متن کاملPremature Ventricular Contraction Coupling Interval Variability Destabilizes Cardiac Neuronal and Electrophysiological Control
Premature ventricular contractions (PVCs) are common in clinical practice. In structurally normal hearts, despite being referred to as benign, PVCs may lead to cardiomyopathy or even to sudden cardiac death. Recent clinical studies have identified factors that predict worse outcomes in PVC patients. Particularly, patients with PVCs showing high coupling interval (CI) variability are at a greate...
متن کاملClassification of Premature Ventricular Contraction in ECG
Cardiac arrhythmia is one of the most important indicators of heart disease. Premature ventricular contractions (PVCs) are a common form of cardiac arrhythmia caused by ectopic heartbeats. The detection of PVCs by means of ECG (electrocardiogram) signals is important for the prediction of possible heart failure. This study focuses on the classification of PVC heartbeats from ECG signals and, in...
