Summary
E point to septal separation (EPSS) in dogs is typically between 1-6mm. Factors like breed, age, sex, or heart rate do not significantly impact EPSS measurements in healthy, non-anesthetized dogs.
Area of Science:
- Veterinary Cardiology
- Echocardiography
- Canine Physiology
Background:
- The mitral valve E point to septal separation (EPSS) is an echocardiographic measurement used to assess left ventricular diastolic function.
- Establishing reference ranges for EPSS in healthy dogs is crucial for accurate diagnosis and monitoring of cardiac conditions.
Purpose of the Study:
- To determine the normal range of mitral valve E point to septal separation (EPSS) in healthy, non-anesthetized dogs.
- To investigate the influence of various physiological factors on EPSS values in canines.
Main Methods:
- Echocardiographic measurements of EPSS were performed in 50 healthy, non-anesthetized Beagle and German Shepherd dogs.
- Data on breed, age, sex, body mass, and heart rate were collected for each subject.
Main Results:
- The mean EPSS value recorded was 3.27 +/- 1.29 mm, with a range of 1 mm to 6 mm.
- No statistically significant effect of breed, age, sex, body mass, or heart rate on EPSS values was observed.
Conclusions:
- This study establishes a normal reference range for EPSS in healthy Beagles and German Shepherds.
- Physiological variables commonly assessed in veterinary practice do not appear to significantly alter EPSS in healthy dogs, simplifying its interpretation.
