THERAPEUTIC CLASS
Cardiac characteristics in the premature ventricular contraction patients with or without ventricular tachycardia
Background/Aims: Frequent (sustained) premature ventricular contractions (PVCs) lead to ventricular tachycardia (VT), which triggers ventricular fibrillation and sudden cardiac death. The cardiac characteristics and risk prediction in frequent/sustained PVC patients with or without VT have been still in need of investigation. Methods: The data from patients with frequent PVCs via 24 h ambulatory electrocardiogram (ECG) monitor were collected at the Department of Cardiology in the First Affiliated Hospital of Harbin Medical University from January 1, 2012 to August 31, 2015. Total 342 patients were grouped into VT group (n=136) and Non-VT group (n=206) based on the presence or absence of VT. Cardiac functional examination and blood tests were carried out on the second day of admission.
