PULSUS BISFERIENS

PULSUS BISFERIENS IS A SINGLE CENTRAL PULSE WAVE WITH TWO PEAKS SEPARATED BY A DISTINCT MID-SYSTOLIC DIP. AN EARLY COMPONENT PERCUSSION WAVE RESULTS FROM RAPID LEFT VENTRICULAR EJECTION. A LATE COMPONENT TIDAL WAVE REPRESENTS A REFLECTED WAVE FROM THE PERIPHERY DUE TO AN ARTERY'S RECOIL EFFECT. IT IS BEST FELT IN THE PERIPHERAL ARTERIES, SUCH AS BRACHIAL AND RADIAL ARTERIES. MOST COMMONLY SEEN IN MIXED AORTIC DISEASE WITH SEVERE AORTIC REGURGITATION AND HYPERTROPHIC OBSTRUCTIVE CARDIOMYOPATHY (HOCM). THIS CAN REMAIN SILENT IN THE CARDIAC DISEASE'S MILDER FORM, PRONOUNCED BY VALSALVA MANEUVER AND AMYL NITRATE. THIS ACTIVITY HELPS IN THE EVALUATION AND TREATMENT OF CARDIAC CONDITIONS ASSOCIATED WITH PULSUS BISFERIENS AND HIGHLIGHTS THE ROLE OF THE INTERPROFESSIONAL TEAM IN EVALUATING AND IMPROVING CARE FOR PATIENTS WITH THIS CONDITION.
