Electrophysiological parameters of WT and CYP2J2-TG mice two weeks after chronic vehicle or isoproterenol infusion.

WT – Wildtype; CYP – CYP2J2 overexpressing mice; TAC – Transverse aortic constriction; HR – Heart rate; bpm – Beats per minute; ms – milliseconds; P – P-wave duration; PR – PR interval; QRS – QRS interval; QTc – QT interval (corrected for heart rate); AV WB – 1∶1 Atrioventricular node conduction capacity ( = Wenckebach point); AV 2∶1 - 2∶1 Atrioventricular node conduction capacity; AVNERP – Atrioventricular node effective refractory period; AERP – Atrial effective refractory period; VERP - Ventricular effective refractory period.p†vs. CYP Vehicle.‡vs. WT ISO.
