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 ...

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 ...

[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 ...

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 ...

Shock waves can be artificially generated by discharge of a high-voltage spark under water. Cardiac SW therapy (CSWT) is performed using a SW generator system designed to address the clinical ...

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 ...
