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.
