The functional heart murmur: a wastebasket diagnosis
Insights
This study categorizes nonorganic heart murmurs into innocent murmurs (including five specific types) and functional murmurs, aiding in bedside diagnosis.
Area of Science:
- Pediatric Cardiology
- Diagnostic Medicine
Background:
- Distinguishing between innocent and functional heart murmurs is crucial for accurate diagnosis.
- Nonorganic murmurs require careful classification to avoid misdiagnosis.
Purpose of the Study:
- To categorize murmurs of nonorganic origin into two main groups: innocent and functional.
- To provide information on the bedside diagnosis of selected nonorganic heart murmurs.
Main Methods:
- Classification of nonorganic murmurs into "innocent" and "functional" categories.
- Detailed discussion of five specific entities within the innocent murmur group.
- Emphasis on bedside diagnostic approaches.
Main Results:
- Innocent murmurs encompass five distinct entities: pulmonary systolic, vibratory systolic, supraclavicular systolic, mammary souffle, and venous hum.
- Functional murmurs are linked to clinically identifiable alterations in circulatory anatomy and/or physiology.
- The study facilitates differentiation between these murmur types.
Conclusions:
- A clear categorization of nonorganic murmurs aids clinical assessment.
- Understanding these categories improves the accuracy of bedside cardiac evaluations.
- This classification framework supports effective diagnosis and management of heart murmurs.
Abstract:
It is extremely helpful for the examiner to separate murmurs of nonorganic origin into one of two categories. The innocent heart murmur group defines five specific entities: the pulmonary systolic murmur, the vibratory systolic murmur, the supraclavicular systolic murmur, the mammary souffle, and the venous hum. All other nonorganic murmurs are classified as functional, and are produced by clinically recognizable alteration in anatomy and/or physiology affecting the circulatory system. This paper discusses each category and provides information regarding bedside diagnosis of selected murmurs.
