There are P waves (+) with regular PP intervals and a rate of 85 beats/min. The P waves have a normal morphology; they are positive in leads I, II, aVF, and V4-V6. This is a stable normal sinus rhythm ...

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 ...

Not all atrial flutters demonstrate the typical "sawtooth" pattern. During the times of lesser conduction on this ECG, the flutter waves are more apparent. The atrial rate is organized at a rate of ...

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 ...

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 ...

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.
