The mnemonic "MR PAN MS RUM AS JECK AR BLOW" would look like this:
1. MR PAN: Mitral Regurgitation and Pan-systolic
- Mitral Regurgitation (MR): A high-pitched, blowing, holosystolic murmur heard best at the apex and radiating towards the left axilla.
- Pan-systolic: Referring to murmurs, like MR, that occur throughout the entire systole.
2. MS RUM: Mitral Stenosis and Rumbling
- Mitral Stenosis (MS): A low-pitched, rumbling diastolic murmur heard best at the apex with the bell of the stethoscope, particularly in the left lateral decubitus position.
- Rumbling: Describes the sound quality of the MS murmur, which is a low-pitched, rumbling noise.
3. AS JECK: Aortic Stenosis and Ejection Click
- Aortic Stenosis (AS): A harsh, systolic ejection murmur heard best at the right second intercostal space and radiating to the carotids.
- Ejection Click (JECK): A sound often heard with valvular aortic stenosis, characterized by a high-pitched click early in systole.
4. AR BLOW: Aortic Regurgitation and Blowing
- Aortic Regurgitation (AR): A high-pitched, blowing, early diastolic murmur heard best along the left sternal border and at the end of expiration.
- Blowing: Describes the sound quality of the AR murmur, which is a high-pitched, blowing sound.
Understanding these pairings is important for recognizing and differentiating heart murmurs during auscultation, a key skill in cardiac examination.
