The electrocardiogram (ECG) is a valuable tool for assessing the cardiac conduction system. The measurements routinely obtained with ECG include heart rate, PR interval, QRS duration and the QT ...
Current methods for assessing perinatal hypoxic conditions did not improve infant outcomes. Various waveform-based and interval-based ECG markers have been suggested, but not directly compared. We ...
A common electrocardiogram finding that has largely been considered insignificant may actually signal an increased risk of atrial fibrillation, the future need for a permanent pacemaker and an ...
QRS interval widening appears to be highly specific for the diagnosis of hyperkalemia in patients with end-stage kidney disease. ECG changes, in general, have poor sensitivities for hyperkalemia in ...
Editor's note: Find the latest COVID-19 news and guidance in Medscape's Coronavirus Resource Center. College athletes who have recently recovered from COVID-19 infection show cardiac abnormalities on ...
The diagnosis is normal sinus rhythm, atrial bigeminy, first-degree atrioventricular (AV) block (prolonged AV conduction), and right bundle branch block (RBBB). The rhythm is slightly irregular, with ...
A recent study to be presented at the American Heart Association (AHA) Scientific Sessions 2022* revealed unexpected changes in the electrical conduction system of the first genetically-modified ...
This cohort study assessed ECG parameters in transgender men and women before and after use of gender-affirming hormone therapies. Testosterone use in transgender men was associated with shorter ...
