- Pulsus bisferiens
In
medicine , pulsus bisferiens, also bisferious pulse or biphasic pulse, is a sign where, onpalpation of thepulse , a double peak percardiac cycle can be appreciated. "Bisferious" means striking twice. Classically, it is detected whenaortic insufficiency exists in association withaortic stenosis , but may also be found in isolated but severeaortic insufficiency , andhypertrophic obstructive cardiomyopathy .Normally arterial pulses are best felt in central arteries like brachial and carotid, but pulsus bisferiens is an exception to that and can be better felt in peripheral arteries like the radial artery. 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).
