Pulsus bisferiens

DiseasesDB	32530

In medicine, pulsus bisferiens, also bisferious pulse or biphasic pulse, is a sign where, on palpation of the pulse, a double peak per cardiac cycle can be appreciated. Bisferious means striking twice. Classically, it is detected when aortic insufficiency exists in association with aortic stenosis, but may also be found in isolated but severe aortic insufficiency, and hypertrophic obstructive cardiomyopathy.

Normally, arterial pulses are best felt in radial arteries but character is better assessed in carotid artery. Pulsus bisferiens is best felt in brachial and femoral arteries. Another such pulse which can be felt better in peripheral arteries is pulsus alternans. The first lift is due to "percussion wave"(P) and the second lift is due to tidal wave (T).

• If P>T - AR>AS
• If T>P - AS>AR

Characteristic causes:

1. Aortic regurgitation (AR)
2. Aortic regugitation with Aortic Stenosis (AR+AS)
3. Hypertrophic cardiomyopathy

• Previously, we found evidence that radial artery pressure wave forms in newborns represent central aortic wave forms, provided that pressure is measured with adequate accuracy. Therefore, we postulated that the neonatal radial artery wave form, like the adult aortic wave form, may contribute to card
