The diagnosis is sinus rhythm with interpolated premature ventricular complexes, in a trigeminal pattern, with retrograde concealed conduction. The rhythm is irregular, but there is a repeating ...

The diagnosis is sinus rhythm, PVCs and echo beats (complexes). The rhythm is irregular but there is a repeating pattern (group beating) with three QRS complexes and a pause. Therefore, the rhythm is ...

The rhythm is either sinus rhythm or not sinus rhythm. Sinus rhythm refers to the origination of the electrical activity coming from the sinus node — also known as the sinoatrial node, or SA node.

This ECG shows ventricular pacing. Note the pacer spike prior to each QRS complex, most apparent in leads V5 and V6. The P waves appear sinus in origin and have no association with the QRS complexes ...

A sinus arrhythmia refers to a problem with the sinus node of the heart. This controls the rhythm of the heart and can be fast (sinus tachycardia) or slow (sinus bradycardia). This article looks at ...

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 ...

With heart rate monitors now standard in smartwatches and fitness trackers, electrocardiograms (ECG/EKG) have rapidly become a common feature in health wearables. The technology aims to assist ...
