Delayed recurrence of complete atrioventricular block following ablation for premature ventricular complexes. [PDF]

J Cardiothorac Surg
A 77-year-old man was admitted for catheter ablation due to frequent premature ventricular complexes (PVCs). Activation mapping revealed that the earliest ventricular activation during the PVC was recorded on the left upper septum, where a clear His ...

Effects of Adaptive Servo-Ventilation on Nocturnal Ventricular Arrhythmia in Heart Failure Patients With Reduced Ejection Fraction and Central Sleep Apnea–An Analysis From the SERVE-HF Major Substudy

Frontiers in Cardiovascular Medicine, 2022
BackgroundThe SERVE-HF trial investigated the effect of treating central sleep apnoea (CSA) with adaptive servo-ventilation (ASV) in patients with heart failure with reduced ejection fraction (HFrEF).ObjectiveThe aim of the present ancillary analysis of ...

Continuously Tested and Used QRS Detection Algorithm: Free Access to the MATLAB Code [PDF]

International Journal Bioautomation, 2019
Each ECG analysis begins with the detection of the QRS complex, which is the most distinguishable wave for initial investigation. Long ago we published an algorithm for ventricular beats (VB) detection in single ECG lead. The classification of normal QRS

Ventricular premature complexes and sudden death after myocardial infarction.

, 1981
Among 1739 male survivors of myocardial infarction, mortality over 5 years was examined in relation to presence of complex ventricular premature complexes (R on T, runs of two or more, multiform or bigeminal complexes) identified during 1 hour of ...

Strain Analysis in Patients with Frequent Premature Ventricular Complexes and Preserved Left Ventricular Function Undergoing Ablation

, 2023
Background: Frequent premature ventricular complexes (PVCs) can cause PVC-induced cardiomyopathy. The value of PVC ablation in patients with preserved left ventricular function in the low–normal range (ejection fraction: 50–55%) is not established ...

Association of premature ventricular complexes and risk of ischemic stroke: A systematic review and meta‐analysis

Clinical Cardiology, 2020
Recent studies have suggested that patients with premature ventricular complexes (PVCs) may have a higher risk of ischemic stroke. However, the data are limited and inconclusive.

Classification of QRS complexes to detect Premature Ventricular Contraction using machine learning techniques

PLoS ONE, 2022
Detection of Premature Ventricular Contractions (PVC) is of crucial importance in the cardiology field, not only to improve the health system but also to reduce the workload of experts who analyze electrocardiograms (ECG) manually.
