Tachycardia describes when the heart beats faster than normal. Sinus rhythm with tachycardia occurs when the sinus node fires electrical impulses abnormally quickly. Inappropriate sinus tachycardia ...

Sinus rhythm (a.k.a. normal sinus rhythm) refers to the normal heart beat originating from the sinoatrial node. This is manifested as an upright P wave in lead II of the ECG. Sinus bradycardia occurs ...

Patients with recent-onset atrial fibrillation commonly undergo immediate restoration of sinus rhythm by pharmacologic or electrical cardioversion. However, whether immediate restoration of sinus ...

The Apple Watch Series 4's transformation from miniature iPhone and fitness tracker to medical device is now complete with the release of the ECG (electrocardiogram) app and irregular heart rhythm ...
