In the present study, the normal electrocardiographic (ECG) values in the adult male Jamunapari breed of the goats were described. The mean heart rate in the goats was 127 +/- 3.46 per minute and ranged 107 and 168. The amplitudes and duration of various waveforms of ECG for six standard limb leads (I, II, III, aVL, aVR and aVF) were estimated. The overall P, QRS and T amplitudes (millivolts) were 0.065 +/- 0.01, 0.47 +/- 0.06 and 0.20 +/- 0.014 respectively. The duration (seconds) of these wave forms were 0.042 +/- 0.005, 0.033 +/- 0.002 and 0.10 +/- 0.014, respectively. The P-R interval and R-R intervals ranged between 0.06- 0.14 and 0.40-0.58 respectively. The average Q-T interval was 0.24 +/- 0.01 second, indicating the time for which the caprine ventricle remained depolarized. The corrected QT interval was also calculated which was found to vary from 0.24 to 0.57. The mean frontal plane vectors for the wave forms P, QRS and T wave forms were +49.99 +/- 6.02, +37.34 +/- 4.05 and +52.26 +/- 6.79 degrees respectively.
