  1. ECG = Electrocardiography, AV/SA block = Second degree AV and SA block, SVPC = Supraventricular premature complexes, VPC = Ventricular premature complexes.*Horses euthanized had the diagnosis confirmed by necroscopy. **Three episodes of ventricular tachycardia (VT) observed.
  2. Diagnoses, survival, duration of ECG recording in hours, mean HR (range), and numbers of arrhythmias. 1= Survived, 0= Euthanized.
