Echocardiogram calculations for the dog using Lotus 123.

Area of Science:

• Veterinary Medicine
• Cardiology
• Biomedical Engineering

Background:

• Echocardiography is crucial for assessing canine cardiac health.
• Establishing normal reference ranges and confidence intervals is essential for accurate diagnosis.
• Previous methods for calculating these values can be cumbersome.

Purpose of the Study:

• To develop a user-friendly software tool for calculating 95% confidence intervals for normal canine echocardiographic dimensions.
• To streamline the process of analyzing echocardiographic data in veterinary cardiology.
• To provide a reliable method for determining the statistical significance of cardiac measurements in dogs.

Main Methods:

• A microcomputer program was developed using Lotus 123 spreadsheet software.
• The program calculates 95% confidence intervals for standard echocardiographic measurements in canines.
• The software also computes other cardiac function parameters.

Main Results:

• The developed program successfully calculates 95% confidence intervals for normal canine echocardiographic dimensions.
• The software provides a practical application for veterinary echocardiography data analysis.
• Confidence intervals for other cardiac function parameters have not yet been determined.

Conclusions:

• This Lotus 123-based program offers an efficient method for obtaining confidence intervals in canine echocardiography.
• The tool can enhance the precision of cardiac assessments in veterinary practice.
• Further development is needed to determine confidence intervals for additional cardiac parameters.
