bisferiens pulse

A double-beat pulse palpated over the carotid or brachial arteries, which is characteristic of obstructive cardiomyopathy and aortic regurgitation; the ascending limb (percussion wave) initially arises rapidly and forcefully, producing a systolic pulse peak, followed by a dip or trough and a second slower and broader positive (tidal wave); in some patients, the pulse is intermittent, and may be evoked by mechanical (Valsalva) or pharmacologic (nitroglycerin or catecholamines) maneuvers.

bisferiens pulse

Cardiology A double-beat pulse palpated over the carotid or brachial arteries, which is characteristic of obstructive cardiomyopathy and aortic regurgitation; the ascending limb–percussion wave initially arises rapidly and forcefully, producing a systolic pulse peak, followed by a dip or trough, and a second slower and broader positive–tidal wave; in some Pts, the pulse is intermittent, and may be evoked by mechanical–Valsalva or pharmacologic–nitroglycerin or catecholamines– maneuvers. Cf Spike-and-dome.

bisferiens pulse

A pulse marked by two systolic peaks on the pulse waveform. It is characteristic of aortic regurgitation (with or without aortic stenosis) and hypertrophic cardiomyopathy. See also: pulse
