Summary
This study presents a new method for measuring systolic time intervals using electrocardiogram, phonocardiogram, and carotid pulse recordings. The automated system efficiently calculates these intervals, aiding in the assessment of ventricular function.
Area of Science:
- Cardiology
- Physiology
- Medical Instrumentation
Background:
- Systolic time intervals (STIs) are crucial for assessing ventricular function.
- Current methods for STI measurement can be time-consuming and labor-intensive.
Purpose of the Study:
- To introduce an automated method for measuring and calculating systolic time intervals.
- To improve the efficiency and accuracy of ventricular function assessment.
Main Methods:
- Utilized polygraph recordings (electrocardiogram, phonocardiogram, carotid pulse contour).
- Employed a digitizing device for coordinate reading.
- Used a minicomputer for interval calculation and data analysis.
Main Results:
- The method allows for measurement and calculation of multiple systolic time intervals.
- Approximately 100 pulse beats can be analyzed within an hour.
- Results can be presented in chart and graph formats for easier interpretation.
Conclusions:
- The described method offers an efficient and comprehensive approach to STI analysis.
- This technique facilitates rapid assessment of changes in ventricular function.
- Automation enhances the utility of STIs in clinical and research settings.
