The normal electrocardiographic studies in healthy Assam hill goats

Abstract

The aim of this study was to determine the normal electrocardiographic (ECG) values for standard lead II in Assam hill goats. The mean heart rate in the goats studied was 103.65 ±4.91 beat per minute and ranged between 90 and 130 bpm. The P voltage in lead II was oriented in the positive direction. No negative P wave was found. The lead II P wave amplitude was 0.1 mV ±0.009 and P wave duration was 0.03s ±0.001. The T wave amplitude and duration were 0.13mV ±0.010 and 0.04s±0.001. The QRS complex amplitude and duration were 0.32mV ± 0.02 and 0.04s ± 0.001. The duration of PR interval, ST interval and QT in lead II recorded are 0.07 ± 0.003, 0.14s ± 0.003 and 0.22s ± 0.001 respectively.
