Korean J Intern Med. 2020;35(6):1371-1384. Published online May 8, 2020
Background/Aims: This study investigated the prognostic power of corrected QT (QTc) interval in patients with acute heart failure (AHF) according to sex.
Methods: We analyzed multicenter Korean Acute Heart Failure registry with patients with AHF admitted from 2011 to 2014. Among them, we analyzed 4..

Korean J Intern Med. 2019;34(5):1030-1039. Published online October 16, 2018
Background/Aims: It is unknown whether different β-blockers (BBs) have variable effects on long-term survival of patients with heart failure with reduced ejection fraction (HFrEF). This study compares the effects of two BBs, carvedilol and bisoprolol, on survival in patients with HFrEF.
Methods: ..

Terminal QRS Complex Distortion on the Admission Electrocardiogram in Anterior Acute Myocardial Infarction and Association with Residual Flow and Infarct Size after Primary Angioplasty
Hyun Suk Yang, Cheol Whan Lee, Myeong-Ki Hong, Dae-Hyuk Moon, Young-Hak Kim, Sang-Gon Lee, Ki-Hoon Han, Jae-Joong Kim, Seong-Wook Park, Seung-Jung Park
Korean J Intern Med. 2005;20(1):21-25. Published online March 31, 2005
BackgroundTerminal QRS complex distortion on admission is a simple and reliable predictor of infarct size in patients with acute myocardial infarction (AMI). It is uncertain, however, whether this reflects reduced myocardial perfusion of the infarct area and a larger area of t..
