Summary
This study establishes normal electrocardiogram (ECG) values for Göttinger mini-pigs, revealing significant correlations between heart rate and various ECG intervals. These findings provide a crucial baseline for mini-pig cardiovascular research.
Area of Science:
- Cardiovascular Physiology
- Veterinary Electrocardiography
- Preclinical Research Models
Context:
- Electrocardiography (ECG) is vital for assessing cardiac function.
- Miniature pigs are increasingly used as preclinical models in biomedical research.
- Establishing species-specific normal physiological parameters is essential for accurate data interpretation.
Purpose:
- To determine and report mean normal values for key electrocardiogram parameters in Göttinger mini-pigs.
- To analyze the polarity and incidence of P, T, and QRS waves across standard ECG leads.
- To investigate correlations between heart rate and ECG interval durations, as well as the electrical axis of the heart.
Summary:
- Mean normal values for heart rate, PR-interval, QRS-complex, and QT-interval were established in 204 Göttinger mini-pigs.
- Analysis included wave polarities, incidences (P, T, QRS, Q, S), T-wave/QRS discordance, and the electrical axis.
- A significant negative correlation was found between heart rate and QT-duration (r = -0.77), with similar trends for PR and QRS durations.
Impact:
- Provides essential reference data for cardiovascular research utilizing Göttinger mini-pigs.
- Facilitates the identification of physiological variations and potential cardiac abnormalities in this model.
- Contributes to the standardization of ECG interpretation in preclinical cardiovascular studies.
