Electrocardiographic indices in local donkeys

Our study on electrocardiographic indices in local donkeys, employing base-apex lead system revealed mean values of heart rate, P amplitude, P durations, P-R interval, r amplitude, S amplitude, QRS duration, S-T segments, T amplitude, T duration, Q-T interval and R-R interval as 40.16±3.72 bpm, 0.175 ±0.011 mV, 0.083±0.0033 sec., 0.21±0.016 sec., 0.041±0.02 mV, 0.825±0.157 mV, 0.081±0.053 sec., 0.193±0.071 sec., 0.56±0.067 mV, 0.093±0.0068 sec., 0.365±0.015 sec. and 1.528±0.11 sec. respectively. QRS was negative and T wave was either positive or biphasic.
