Normal First Heart Sound, Minimally Split

Easy Auscultation Staff — Wed, 14 Jul 2010 00:48:07 +0000

Chestpiece Position: Tricuspid
Maneuver: Supine

On occasion the first heart sound can be made up of two separate sounds separated by a very small interval (20-30 milliseconds).

The Mitral component (caused by closure of the Mitral valve) comes first and is louder than the Tricuspid component (caused by closure of the Tricuspid valve).

A minimally split first heart sound is a normal variation of the first heart sound.

Loud First Heart Sound

Chestpiece Position: Mitral
Maneuver: Supine

Usually, the first heart sound is slightly louder than the second heart sound when heard in the Mitral valve area.

In this case the first heart sound is much louder than the second heart sound. This can be produced by a thickened, but still mobile, mitral valve. Look at the anatomy tab to see the thickened mitral valve leaflets.

A very loud first heart sound can be an indication of mitral stenosis.

To listen to the audio track of the following videos, we recommend using headphones or earphones.

Normal first and second heart sounds unsplit

This heart sound is at 60 beats per minute. You are listening at the Mitral valve area (Apex). The first heart sound has slightly greater intensity than the second heart sound.

The first heart sound is produced by the closing of the mitral valve leaflets.
The second heart sound is produced by the closing of the the aortic valve leaflets.
The second heart sound is unsplit when the subject is holding his or her breath at peak expiration.

This short movie will display the waveform for a normal first and second heart sound. Headphones should be used during listening.

Note that for this normal heart sound S1 is louder than S2 and is not split while S2 is split.

The time between S1 and S2 is the systolic interval
The time between S2 and the next S1 is the diastolic interval
