Fragmented QRS and abnormal creatine kinase-MB are predictors of coronary artery disease in patients with angina and normal electrocardiographys
Jung Joo Lee, Jae Hoon Lee, Jin Woo Jeong, Jun Young Chung
Korean J Intern Med. 2017;32(3):469-477. Published online April 17, 2017
Background/Aims: Patients with symptoms of coronary artery disease (CAD) often display normal tracings or only nonspecific changes on electrocardiography (ECG). The aim of this study was to explore strategic elements of the ECG and other potential factors that are predictive of CAD in this scenario...

Features of electrocardiogram in patients with stenosis of the proximal right coronary artery
Moo Seong Koh, Jae Hoon Lee, Jin Woo Jeong, Jun Young Chung
Korean J Intern Med. 2017;32(2):277-285. Published online February 14, 2017
Background/Aims: Prediction of lesions of the proximal right coronary artery (pRCA) through electrocardiogram (ECG) is very important because pRCA occlusion has many complications and a high mortality rate, which has frequently been related with right ventricular infarction. The purpose of this stud..

Prognostic value of computed tomographic coronary angiography and exercise electrocardiography for cardiovascular events
Kye-Hwan Kim, Kyung Nyeo Jeon, Min Gyu Kang, Jong Hwa Ahn, Jin-Sin Koh, Yongwhi Park, Seok-Jae Hwang, Young-Hoon Jeong, Choong Hwan Kwak, Jin-Yong Hwang, Jeong Rang Park
Korean J Intern Med. 2016;31(5):880-890. Published online March 25, 2016
Background/Aims: This study is a head-to-head comparison of predictive values for long-term cardiovascular outcomes between exercise electrocardiography (ex-ECG) and computed tomography coronary angiography (CTCA) in patients with chest pain.
Methods: Four hundred and forty-two patients (mean age, ..

Clinical significance of changes in the corrected QT interval in stress-induced cardiomyopathy
Jung-Hee Lee, Jae-Sun Uhm, Dong Geum Shin, Boyoung Joung, Hui-Nam Pak, Young-Guk Ko, Geu-Ru Hong, Moon-Hyoung Lee
Korean J Intern Med. 2016;31(3):507-516. Published online April 7, 2016
Background/Aims: Although transient changes in the electrocardiogram (ECG) of patients with stress-induced cardiomyopathy (SCMP) are common, there are little data about ECG changes in patients with SCMP and the clinical implications of these variations.
Methods: We investigated a total of 128 pati..

Electrocardiographic artefacts mimicking atrial tachycardia resulted in unnecessary diagnostic and therapeutic measures
Shams Y-Hassan, Christer Sylvén
Korean J Intern Med. 2013;28(2):224-230. Published online February 27, 2013
Electrocardiographic (ECG) artefacts may closely simulate both supraventricular and ventricular tachycardias. We describe a case initially diagnosed as rapid atrial fibrillation, based on 12-lead surface ECG (especially the limb leads) and monitor tracing. The arrhythmia was resistant to beta blo..

Normalization of Negative T-Wave on Electrocardiography and Right Ventricular Dysfunction in Patients with an Acute Pulmonary Embolism
Bo-Youn Choi, Dae-Gyun Park
Korean J Intern Med. 2012;27(1):53-59. Published online February 28, 2012
Background/AimsRight ventricular dysfunction (RVD) is associated with poor prognosis in patients with acute pulmonary embolism (APE). Echocardiography and computed tomography (CT)-angiography may be difficult to perform in a serial follow up, unlike electrocardiography (ECG). ..

Variable Association between Components of the Metabolic Syndrome and Electrocardiographic Abnormalities in Korean Adults
Hong-Kyu Kim, Chul-Hee Kim, Kwan-Ho Ko, Seong-Wook Park, Joong-Yeol Park, Ki-Up Lee
Korean J Intern Med. 2010;25(2):174-180. Published online June 1, 2010
Background/AimsResting electrocardiogram (ECG) abnormalities have been strongly associated with cardiovascular disease mortality. Little is known, however, about the association between individual components of metabolic syndrome and ECG abnormalities, especially in Asian popu..
