BACKGROUND The clinical importance of the J-point elevation on electrocardiogram is controversial. OBJECTIVE To study intracardiac J-point amplitude before ventricular arrhythmia. METHODS Baseline 12-lead electrocardiogram and far-field right ventricular intracardiac implantable cardioverter-defibrillator electrograms were recorded at rest in 494 patients (mean age 60.4 ± 13.1 years; 360 [72.9%] men) with structural heart disease (278 [56.3%] ischemic cardiomyopathy) who received primary… CONTINUE READING
