Preliminary reference values for electrocardiography, echocardiography and myocardial morphometry in the European brown hare (Lepus europaeus).

ABSTRACT: The study aimed at defining reference values for electrocardiographic (ECG) and echocardiographic parameters as well as macroscopic dimensions of the heart and microscopic dimensions of cardiomyocytes in the European brown hare. The studies were conducted on 30 adult, clinically healthy hares of either sex caught in Poland. ECG and echocardiography were performed supravitally on anaesthetized hares. After euthanasia, gross and microscopic myocardial and cardiomyocyte dimensions were determined. Heart rate amounted to 140 +/- 37.5 beats/min, the leading rhythm involved the sinus rhythm. P wave time was 26 +/- 5 ms, PQ time was 80 ms, QRS time was 29 +/- 3.5 ms, and ST was 97.5 +/- 7 ms. Echocardiography determined a left ventricular wall end-diastolic diameter of 8.6 +/- 2.0 mm and an intra
