  1. No swelling and normal mental status were assigned 1, and mild(ly), moderate(ly), and severe(ly) swelling and depressed mental status were assigned 2, 3, and 4 respectively. Dogs without pathologic arrhythmias had less than 50 single and sporadic VPCs per 24 h. Dogs with pathologic arrhythmias had more than 50 VPCs per 24 h, couplets of VPCs, VT or R-on-T. Group data is presented as medians and interquartile range (IQR)
