Abstract

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.

摘要

在本研究中，描述了成年雄性Jamunapari品种山羊的正常心电图（ECG）值。山羊的平均心率为每分钟127±3.46次，范围在107至168次之间。估计了六个标准肢体导联（I、II、III、aVL、aVR和aVF）心电图各种波形的幅度和持续时间。总的P、QRS和T波幅度（毫伏）分别为0.065±0.01、0.47±0.06和0.20±0.014。这些波形的持续时间（秒）分别为0.042±0.005、0.033±0.002和0.10±0.014。P-R间期和R-R间期分别在0.06 - 0.14和0.40 - 0.58之间。平均Q-T间期为0.24±0.01秒，表明山羊心室保持去极化的时间。还计算了校正后的QT间期，发现其范围在0.24至0.57之间。波形P、QRS和T波的平均额面向量分别为+49.99±6.02、+37.34±4.05和+52.26±6.79度。
