Blood Pressure - Korotkoff Sounds 2

Korotkoff Sounds - Blood pressure sounds with slowly deflating cuff. Notice that slower deflation provides for more beats and potentially increased accuracy for onset of systole or detection of diastolic end-point.

Coarctation of the Aorta

Coarctation of the Aorta - Usually occurs proximal to the origin of the left subclavian artery. The murmur is best heard with the stethoscope positioned Posteriorly in the left suprascapular region using the diaphragm mode. A thrill may be palpable over the left ribs posteriorly due to collateral arteries involving the intercostals arteries.

Congestive Heart Failure (S3)

Congestive Heart Failure - Noticeable third heart sound (S3) during diastole following S2, producing galloping sound. S3 is extremely low frequency and requires good headphones with sealed eartips to hear clearly. Due to low frequency content, set stethoscope to Bell mode.

Hypertrophic Cardiomyopathy

Hypertrophic Cardiomyopathy

The recording was made with the patient supine. The stethoscope is positioned in the 3rd - 4th intercostal space along the left parasternal border i.e just to the left of the sternum using the diaphragm mode. The stethoscope is over the left ventricular outflow tract, below the level of the aortic valve.

The obstruction is "dynamic", i.e the obstruction becomes progressively more severe as the ventricle contracts. The murmur therefore increases in intensity during systole as the obstruction increases.

 

 

The murmur may be confused with that of aortic stenosis. Note however that the aortic component of the second heart sound is easily audible, whereas in aortic stenosis the second heart sound is usually soft.
