From: Twenty-four-hour ambulatory electrocardiography characterization of heart rhythm in Vipera berus-envenomed dogs

Fig. 1

24-h ambulatory electrocardiography strips recorded from selected dogs envenomed by Vipera berus to illustrate some abnormalities of ventricular depolarization used to separate dogs with and without pathologic arrhythmias. Dogs with the following abnormalities were considered to have pathologic arrhythmias. a More than 50 single ventricular premature complex (VPC) (arrow). b Couplets of VPCs (arrow). c Episodes of ventricular tachycardia. d “R-on-T phenomenon” (arrow)
