Premature Ventricular Contraction-Induced Systolic Heart Failure: A Treatable Condition
Several clinical predictors of VPD-induced cardiomyopathy and HF have been identified. Classically, a high VPD burden of more than 24% has been associated with impaired LVEF and HF [13]. A longitudinal study found subclinical deterioration in LVEF over 5 years in those with a high burden of VPDs (≥ 10-20%) [14]. Despite the absence of a definitive and clear cutoff, the risk of developing NICM a...
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...
متن کاملCharacterization and Treatment of the Malignant Premature Ventricular Contraction
The majority of deaths from acute myocardial infarction (AMI) occur prior to the arrival of medical aid and appear to be due to ventricular fibrillation (VF). Since the premature ventricular contraction and bradyeardia are believed to predispose to VF, it has been suggested that administration of atropine or lidocaine during the prehospital phase of AMI may effectively reduce mortality in AMI. ...

متن کاملCirculating KCNH2 Current-Activating Factor in Patients with Heart Failure and Ventricular Tachyarrhythmia
BACKGROUND It is estimated that approximately half of the deaths in patients with HF are sudden and that the most likely causes of sudden death are lethal ventricular tachyarrhythmias such as ventricular tachycardia (VT) or fibrillation (VF). However, the precise mechanism of ventricular tachyarrhythmias remains unknown. The KCNH2 channel conducting the delayed rectifier K(+) current (I(Kr)) is...
