Radiofrequency Catheter Ablation of Idiopathic Right Ventricular Outflow Tract Arrhythmias

Indian Pacing and Electrophysiology Journal, 2013
Idiopathic ventricular arrhythmias (VA) consist of various subtypes of VA that occur in the absence of clinically apparent structural heart disease. Affected patients account for approximately 10% of all patients referred for evaluation of ventricular ...

The Management of Patients with Premature Ventricular Contractions

, 1979
Premature ventricular contractions (PVCs) occur frequently in patients with virtually all types of cardiac disease and in persons without evidence of cardiac disease.

A Review: Detection of Premature Ventricular Contraction Beat of ECG [PDF]

, 2020
: ECG signal is a periodic signal that gives information about the heart activity. A lot of information about normal and abnormality about the heart can be obtained from the ECG signal. Premature ventricular contractions (PVCs) are the ectopic beats that

PVC Variability and Impact on Meeting Expert Consensus Cutoffs of ≥ 10 000 PVCs/Day and ≥ 15% PVCs

Journal of Cardiovascular Electrophysiology, EarlyView.
14‐day Zio® (iRhythm) datasets of 606 patients between December 2018 and January 2019 who had at least one day of ≥10,000 PVCs were acquired. Of these patients, a subcohort of 325 patients who had at least one day of ≥15% PVCs was generated. In both groups, analyses were carried out showing that longer duration monitoring increased sensitivity for ...

Detecting Premature Ventricular Contractions in ECG Signals With Gaussian Processes [PDF]

, 2008
The aim of this work is twofold. First, we propose to investigate the capabilities of a new Bayesian approach for detecting premature ventricular contractions (PVCs), namely the Gaussian process (GP) approach. Second, we report an experimental comparison

Long‐Term Serial Exercise Stress Testing in Catecholaminergic Polymorphic Ventricular Tachycardia on Beta‐Blocker and Flecainide Therapy

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a potentially life‐threatening arrhythmic disorder typically treated with beta‐blockers and, occasionally, with flecainide. Methods All patients underwent genetic testing, electrocardiogram, echocardiogram, and exercise testing.

Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

Journal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

Natural history of ventricular premature contractions in children with a structurally normal heart: does origin matter?

, 2008
Aims Premature ventricular contractions (PVCs) are thought to be innocent in children with normal hearts, especially if they disappear during exercise.
