Paradoxic pulse

Definitions
1. an exaggeration of the normal variation in the systemic arterial pulse volume with respiration, becoming weaker with inspiration and stronger with expiration; characteristic of cardiac tamponade, rare in constrictive pericarditis; so called because these changes are independent of changes in the cardiac rate as measured directly or by electrocardiogram.
