Comparison of P-wave dispersion in healthy dogs dogs with chronic valvular disease and dogs with disturbances of supraventricular conduction

摘要

BackgroundP-wave dispersion (Pd) is a new ECG index used in human cardiology and veterinary medicine. It is defined as the difference between the maximum and the minimum P-wave duration recorded from multiple different ECG leads. So far no studies were performed assessing the importance of P-wave dispersion in dogs.
