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 ...

MANY common arrhythmias observed in both atria and ventricles are similar although the atrial types have a few important distinguishing features. Thus, so far as therapy is concerned, the atrial ...

The retrospective study population included 61 patients (29 men) with a mean age of 42 ± 5 years. Echocardiography showed normal LA (33.4 ± 1.5 mm) and normal ejection fraction (63.1 ± 2.3%). Two ...

A 67-year-old man with acute anterolateral myocardial infarction had recurrent ventricular fibrillation that required insertion of temporary pacemaker. When a permanent pacemaker was inserted stable ...

The QRSs are wider than and different from other QRSs, raising a possibility of PVC. But they are clearly preceded by a prematurely occurring P wave and so are PAC with aberrant conduction. Aberrant ...

A 62 year old male with a history of hypertension presents with intermittent palpitations. He began to have the palpitations in clinic and below is his ECG. What are the ECG findings? Atrial ...

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 ...
