bisferiens pulse

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.
