Analysis of base apex lead electrocardiograms of domestic donkey

To determine the normal electrocardiogram parameters in donkey this study was carried out on 46 healthy donkeys, ranging age from 2 to 12 years. A base apex lead ECG was recorded from each donkey at paper speed 25mm/sec and calibration of 10mm. equal to one mV. Heart rate, amplitudes, configuration and intervals of waveform were recorded on ECG Results showed that mean heart rate was 55.47± 10.93 beats/min and the P wave was generally positive and biphasic. The mean of P, Q, r, S and T wave amplitudes were (0.27±0.04), (2.2±0.4), (0.13±0.09), (2.2±0.4) and (0.63±0.3) mV, respectively. Two patterns of QRS complex (rS and QS) and three patterns of the T wave (negative, 15.22%; positive, 26.08%; and biphasic; 58.7%) were also recognized. Duration of PR, RR, QT and PP intervals, TP segment and QRS complex, P and T waves were as follows: PR)0.24±0.05(, RR)1±0.2(, QT)0.46±0.08( and PP)1±0.24(, TP)0.2±0.04(, QRS)0.1±0.01(, P)0.1±0.01( and T)0.16±0.04).
