Background:

Heart sound analysis is crucial for diagnosing cardiac conditions.
Existing heart sound segmentation methods struggle with elevated heart rates and require lengthy signal acquisition.
Clinical limitations necessitate more efficient and robust segmentation techniques.

Purpose of the Study:

To develop and evaluate a novel heart sound segmentation method.
To overcome limitations of existing approaches, particularly in pediatric and high heart rate scenarios.
To utilize structural and energy-based features independent of commonly used critical features.

Main Methods:

Heart sound segmentation using structural features.
Heart sound segmentation using energy-based features.
Evaluation of sensitivity and specificity of the proposed method.

Main Results:

The proposed method demonstrates effective heart sound segmentation.
High sensitivity and specificity were achieved, comparable to existing literature.
The approach shows promise for scenarios with elevated heart rates.

Conclusions:

The developed heart sound segmentation technique offers a viable alternative to current methods.
Structural and energy-based features provide a robust basis for heart sound analysis.
This method has potential for practical application in clinical cardiology, especially in challenging cases.
