Electrocardiographic and vectorcardiographic response to right ventricular hypertrophy in the goat

Basic differences were observed in the elctrocardiographic and vectorcardiogrpahic response to RVH in goats when compared to man and dogs. Instead of RVH inducing a redistribution of major fronts of electrical activity which result in profound QRS complex alterations as in man and dogs, it appears to produce no significant alteration of the QRS complex or major vector orientation in goats. Although slight reorientation of sagittal and horizontal vector forces occurred during development of RVH, no statistically significant changes could be detected.
