Abstract
Electrocardiograms and vectorcardiograms of 11 normal monkeys placed in dorsal-supine, rightlateral, left-lateral, and sitting positions were analyzed and results presented. This information is of immediate importance in determining electrocardiographic and vectorcardiographic changes that may be induced in monkeys by lateral impact. Leads taken were I, II, III, aVR, aVL, aVF, MV1, MV2, and MV3. Parameters analyzed from the electrocardiogram lead II included: rhythm, rate, PR interval, P wave duration, PQ segment duration, and QRS duration. The mean P vector projection in the frontal plane was also calculated. Amplitudes of the component deflections in leads I, aVF, and MV1 were determined. Vectorcardiograms were analyzed for: direction of inscription, ratio of length to width, and the mean axis of the QRS vector projected on the three planes for each body posture. This report will serve as a base line for analysis for electrocardiographic or vectorcardiographic data analyzed in experiments on monkeys placed in any of the four positions.
