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 ...

[Andrade J, et al. Circ Res. 2014;4a] The diagnosis of AF is confirmed with a standard 12-lead ECG. P waves are absent, coarse “fibrillatory waves” can frequently be seen and sometimes no ...

When left atrial enlargement occurs, it takes longer for cardiac action potentials to travel through the atrial myocardium; thus, the P wave also lengthens. Therefore, the criteria for diagnosing ...

Sinus rhythm resumes with increased heart rates during exercise. In an ectopic atrial rhythm, P waves are present but are a different morphology compared to the sinus P wave. Ectopic P waves are most ...

Abnormal findings are unrelated to regular training and also found in underlying pathological cardiac conditions. These include findings suggestive of cardiomyopathy such as T-wave inversion, ST ...
