The R12 and R14 waves hold the key to the answer (Figures 2 and 3). These two QRS complexes are narrow and occur slightly earlier than others. They are PJCs and occur late enough to have a sinus P ...

If it’s important that an ECG is done, it’s important that it’s legible. Asking patients to hold their breath for a couple of seconds can help, or if fine tremor is a problem, try moving the limb ...

Communicating concerns about nonspecific changes on ECG Exercise caution when a patient presents with acute chest pain. The ability to explain the situation as clearly as possible is essential.

A new study has linked prolonged P-wave duration to increased risk for sudden cardiac death (SCD), independent of cardiovascular risk factors and atrial fibrillation. 1 This suggests P-wave duration ...

The ECG findings of hyperkalemia change as the potassium level increases. From earliest to latest, the ECG findings include: Peaked T waves best seen in the precordial leads, shortened QT interval and ...

Wandering atrial pacemaker is similar to multifocal atrial tachycardia except the heart rate is normal ― that is, less than 100 beats per minute. Wandering atrial pacemaker occurs when multiple areas ...

Background In athletes, ECG changes from physiological cardiac remodelling are common but can overlap with findings from a pathological disorder. We compared ECG findings in a group of elite high ...
