The electrocardiographic (ECG) parameters in the normal Korean black goat have been measured with a 3-channel Electrocardiograph and computed, analyzed. ECG in 243 black goats were made with the limb leads (I, II, III, aVR, aVL, aVF), that were recorded conduction parameters of wave and interval, and were analyzed as to shape and amplitude of the P and T waves and the components of the QRS complex. Heart rate were recorded by the ECG which were a mean of 106.1$pm $21.8 beats/min. Average conduction times in the PR, the QRS complex and the QTc interval were recorded 103.9$pm $34.9 msec., 58.3$pm $23.2 msec. and 302.6$pm $67.8 msec., in the P and T wave duration recorded 24.8$pm $6.4 msec. and 51.7$pm $10.8 msec. respectively. The shape of wave in each leads were observed various types, and any spacial wave type appeared the highest frequency in each lead that ware shown less than 60%, and these frequent rate and average amplitudes as fallow: 1. In P waver the frequent rate and average amplitudes of the positive type showed in leads I, II and aVL that were 54.8% (93.0$pm $ 33.2 $mu $V), 50.5% (90.1$pm $30.5 $mu $V) and 41.7% (58.5$pm $ 31.1 $mu $V). Average amplitude of the negative type showed the frequent rate of 49.8% in lead aVE which was -77.6$pm$ 25.2 $mu $V. Biphasic type in leads III and aVF were 46.1% (108.4 $mu $V, -90.2 $mu $V.) and 45.7% (137.4 $mu $V, -105.4 $mu $V.), and amplitudes between positive and negative of it were significant difference. 2. The highest amplitudes of the QRS complex in all leads were 534.8$pm $ 232.3 $mu $V of lead II. The frequent rate and amplitudes of the R wave type in the I, II, III and aVF were 30.2% (277.8 $pm $131.3 $mu $V), 45.1% (393.1$pm $114.2 $mu $V), 48.5% (349.3$pm $178.3 $mu $V) and 54.9% (334.4$pm $129.7 $mu $V), and QS ways type in the lead aVL was 49.5% (359.2$pm $195.5$mu $V), and RS and QS wave types in the lead a VR were 43.3% (312.4 $mu $V, -212.7 $mu $V.) and 41.1% (399.2$pm $92.2 $mu $V), respectively. 3. In T wave, the frequent rata and amplitudes of the positive type in the leads I, II, III and aVF were 44.6% (207.9$pm $ 97.1 $mu $V), 41.6% (245.1$pm $92.1 $mu $V), 46.9% (189.8$pm $ 82.7 $mu $V) and 53.0% (195.4197.8 $mu $V), and the negative in the lead aVR was 41.2% (-230.7$pm$ 103.1 $mu $V), respectively. The positive and negative types in the lead aVe appeared with same frequent rate of 43.2%.4. Frontal plane vectors for P, QRS, and T were found to lie at 38.1$pm $ 21.5, 142.0$pm $ 57.2, and 117.2$pm $ 63.9 degrees, respectively. These results in ECG of goats may be served to the limited purposes as to conduction parameters, arrhythmias except abnormal ECG because of waveforms, amplitudes and electrical axis of it were variability.
