Paradoxical pulse)
In medicine, a pulsus paradoxus (PP), also paradoxic pulse and paradoxical pulse, is a sign that is indicative of several conditions including cardiac tamponade and obstructive lung diseases (e.g. asthma).[1]
The paradox in pulsus paradoxus is that one can detect extra beats in cardiac auscultation when compared to the radial pulse. PP is quantified using a blood pressure cuff and stethoscope, by measuring the variation of the pressure in systole with respiration. Normal systolic blood pressure variation (with respiration) is considered to be 10 mmHg.[1]
PP has been shown to be predictive of the severity of cardiac tamponade.[2]
