Online published on 20 November, 2017. Abstract The investigation was undertaken in 250 adult pigeons of which 180 pigeons were clinically healthy having no signs of illness and were used to determine reference values of electrocardiographic parameters in standard lead II. P wave was positive and monophasic in all leads except aVR and aVL. PR segment was almost absent, ‘R’ was very small rather imperceptible in many pigeons, ’S’ wave was marked and ‘QRS’ pattern was of the rS type and negative in lead II, III and avF, ST slurring (absence of ST) was observed in 95% pigeons, ‘T’ wave was generally positive in lead I, II, III and avF and negative in aVL and aVR. The mean electrical axis on frontal plane was-83.52±6.080 with a predominant negative ‘S’ wave. Remaining 70 pigeons with various ailments showed various types of electrocardiographic abnormalities (sinus bradycardia, sinus tachycardia, atrial fibrillation/flutter, ventricular premature complex, ventricular tachycardia, ventricular flutter, ventricular asystole, 2nd degree heart blocks, right bundle branch block, low voltage complex and Ta wave).
