ECG tracings of one wild-type (WT) and two transgenic (TG) mice. A: WT mouse, RR 117 ms, basal heart rate (HR) 513 bpm, QT 60 ms. B: TG Mouse, RR 119 ms, basal HR 506 bpm, QT 74 ms. C: TG mouse, 6 minutes after 0.5 mg/kg carbachol intraperitoneal. A and B illustrate the longer QT interval, for the same HR, present in TG vs WT mice. C shows the occurrence of what looks like an episode of torsades de pointes ventricular tachycardia in a TG mouse exposed to carbachol.
