Studies Into Equine Electrocardiography and Vectorcardiography

III Vector Distribution in some Cardiovascular Disorders

J R Holmes, B J Alps
PMCID: PMC1494718  PMID: 4227914

Abstract

The paper describes observations on the distributions of the P, QRS and T cardiac vectors in the horizontal plane, comparing healthy horses with those with arrhythmia and cardiac murmurs. Deviation of the T vector from the normal range appeared to occur most commonly in association with cardiac murmurs, particularly those involving the semilunar valves and aorta.
