Fig. 1From: Ventricular bigeminy associated with myocardial ischemia in a dog with a colonic torsion: a case reportLead II ECG recording from a multiparameter monitor. On the recording, ventricular premature complexes (VPCs) display a right bundle branch block morphology organized in bigeminy. The ventricular ectopic beats (red arrow) are premature, widened, and bizarre with no preceding p-wave. The ventricular ectopic beats (red arrow) alternate with sinus beats (blue arrows) in a 1:1 arrangementBack to article page
