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 ...
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 ...
June 23, 2009 (Boston, Massachusetts) — Prolongation of the PR interval in the ambulatory setting is associated with increased risks of atrial fibrillation, pacemaker implantation, and all-cause ...
The ECG shows sinus tachycardia at about 115 beats per minute with a PR interval of about 0.15 sec (normal). The P waves show normal duration, but they are peaked in II, II and AVF and their amplitude ...
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 ...
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 ...
There are regular P waves at a rate of 60 beats per minute. The QRS complexes show “grouped beating.” Three of the first four P waves are conducted with increasing PR intervals; the first beat is ...
You are reviewing an ECG you arranged for a 56-year-old man with newly diagnosed hypertension. The trace is normal but the computerised report notes ‘first-degree heart block’. Looking at the ...
