Paired narrow QRS complexes, each preceded by a P wave, certainly raise the possibility of atrial bigeminy. But there are other causes of paired QRS complexes during sinus rhythm. One should look ...

A new study finds an association between baseline P-wave morphology and subsequent ischemic stroke risk, even after accounting for atrial fibrillation (AF). The significant association between P-wave ...

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 ...
