Figure 2. Repeated 12-lead electrocardiography demonstrated bigeminal premature ventricular complexes (PVCs) with a left bundle branch block QRS pattern and tall R waves in the inferior leads.

Lead I (top) and lead II (bottom) from KardiaMobile 6L showing sinus rhythm with PVCs read as unclassified Kardia is not alone in being confused by PVCs and PACs. Apple Watch has the same problem.

The PVC is not associated with a pause, ... Cite this: ECG Challenge: Sinus Rhythm, but What Else? - Medscape - Apr 18, 2017. Authors and Disclosures. Authors and Disclosures Author ...

EXPERIMENTAL studies1 2 3 suggested that certain chemical structures might be capable of suppressing ventricular arrhythmia without possessing some of the actions previously associated with antiarr ...

As soon as the table was returned to the flat supine position, however, the sinus rate rapidly slowed from 110 to 55 beats/min and PVCs developed in a bigeminal cycle, followed by an 8-beat run of ...
