title: Electrocardiographic parameters of free-ranging roe deer (Capreolus capreolus).
abstract: Electrocardiographic parameters were measured in 28 free-ranging roe deer (Capreolus capreolus). The electrocardiograms (ECGs) were recorded in base-apex lead, standard bipolar limb leads (I, II, III), and augmented unipolar limb leads (aVR, aVL, aVF). Morphology and amplitude of P waves, QRS complexes, and T waves were analyzed in all seven leads. Cardiac rhythm, heart rate, and durations of P, QRS, and T waves, PR interval, QTc interval, and ST segment were calculated in the base-apex lead. The mean electrical axis for each individual was determined from the net amplitude of the QRS complex in leads I and II. All of the animals had a sinus rhythm. Heart rates ranged from 60-180 beats per minute, with a mean +/- SD of 104.8 +/- 44.1. The electrical axis was 100 degrees-220 degrees, with a mean +/- SD of 169.5 degrees +/- 40.8 degrees. The base-apex lead provided the most uniform ECG patterns and higher mean amplitudes than did standard leads.
