Osborn Waves: History and Significance [PDF]

, 2004
The Osborn wave is a deflection with a dome or hump configuration occurring at the R-ST junction (J point) on the ECG (Fig. 1). In the historical view, different names have been used for this wave in the medical literature, such as “camel-hump sign ...

Suppression of premature ventricular complexes with the PDE5 inhibitor sildenafil: First clinical experience

Experimental Physiology, EarlyView.
Abstract The phosphodiesterase‐5 inhibitor sildenafil suppresses ventricular arrhythmias in a sheep model of drug‐induced long QT. In that study, ventricular arrhythmias were abolished by reducing premature ventricular complexes (PVCs) and delaying PVC onset, thus preventing ‘R‐on‐T’ ventricular tachycardia.

Cardiac‐specific Kv1.1 deficiency alters cardiomyocyte electrophysiology without modifying overall cardiac function or arrhythmia susceptibility

Experimental Physiology, EarlyView.
Abstract The leading cause of epilepsy‐related mortality is sudden unexpected death in epilepsy (SUDEP), resulting from seizure‐induced cardiorespiratory arrest by mechanisms that remain unresolved. Mutations in ion channel genes expressed in both brain and heart represent SUDEP risk factors because they can disrupt neural and cardiac rhythms ...
