    Impact of signal-averaged electrocardiography findings on appropriate shocks in prophylactic implantable cardioverter defibrillator patients with nonischemic systolic heart failure

    Implantable cardioverter defibrillators (ICDs) are a potential treatment for preventing sudden cardiac death (SCD) in patients with low left ventricular ejection fraction (LVEF) and myocardial infarction/heart failure (HF), and ICDs have been …

  10. Open Access 01-12-2021 | Resting ECG | OriginalPaper

    Clinical values of resting electrocardiography in patients with known or suspected chronic coronary artery disease: a stress perfusion cardiac MRI study

    Coronary artery disease (CAD) is one of the leading causes of morbidity and mortality worldwide [ 1 ]. Assessment of the pretest probability of CAD is crucial to select the most appropriate diagnostic test. The Diamond-Forrester (DF) model is one …

  11. Open Access 06-03-2023 | Sudden Cardiac Death | ReviewPaper

    Noninvasive electrocardiographic risk factors for sudden cardiac death in dilated ca rdiomyopathy: is ambulatory electrocardiography still relevant?

    Risk stratification for sudden cardiac death in dilated cardiomyopathy is a field of constant debate, and the currently proposed criteria have been widely questioned due to their low positive and negative predictive value. In this study, we …

    Machine Learning in Electrocardiography and Echocardiography: Technological Advances in Clinical Cardiology

    Electrocardiography (ECG) and echocardiography are two of the most widely used diagnostic tools for cardiovascular disorders. ECG measures the heart’s electrophysiology. Echocardiography observes cardiac structure and function [ 1 – 4 ]. As more …

  13. Open Access 01-12-2020 | Myocarditis | OriginalPaper

    The diagnostic capability of electrocardiography on the cardiogenic shock in the patients with acute myocarditis

    Myocarditis is a inflammatory disease involving injury of the cardiac myocytes, the incidence of which is estimated approximate 0.02–0.1% in the general population [ 1 , 2 ]. Fulminant myocarditis (FM), the most severe type, is characterized with …
