Clinical signs in medicine: pulsus paradoxus.

چکیده
Historical Aspects The reduction in pulse volume during inspiration was first described by Lomer in 1669 in constrictive pericarditis1. A similar finding was described by Floyer and later by William in 1850 in bronchial asthma1. Adolf Kussmaul (Freiberg, Germany) coined the term pulsus paradoxus in 1873 in three patients with constrictive pericarditis. The paradox was: (1) the discrepancy between the absence of the pulse and present corresponding heart beat and (2) Amidst this irregularity, the regularity with which the pulse disappeared during inspiration.1

Increased jugular venous pressure with inspiration is commonly referred to as Kussmaul’s sign; and the disappearance of the radial pulse or a drop in systolic blood pressure of 10 mmHg or greater with inspiration is recognized as pulsus paradoxus. Both Kussmaul’s sign and pulsus paradoxus are commonly attributed to the discoveries of Dr. Adolf Kussmaul. Together these two clinical signs are imp...
متن کاملMechanism of pulsus paradoxus in clinical shock.
An inspiratory fall in systolic arterial pressure of more than 10 mm Hg (pulsus paradoxus) was noted in 30 of 61 patients with shock. Inspiratory right atrial pressures and total blood volumes were significantly lower in patients with pulsus paradoxus. Rapid infusion of dextran in 22 patients usually was effective in reversing the exaggerated inspiratory fall in systolic pressure. Total periphe...
متن کاملPulsus paradoxus.
Systolic blood pressure normally falls during quiet inspiration in normal individuals. Pulsus paradoxus is defined as a fall of systolic blood pressure of >10 mmHg during the inspiratory phase. Pulsus paradoxus can be observed in cardiac tamponade and in conditions where intrathoracic pressure swings are exaggerated or the right ventricle is distended, such as severe acute asthma or exacerbatio...
متن کاملPulsus paradoxus in ventilated and non-ventilated patients.
Human physiology changes are often amplified in disease states and may be altered when a patient is mechanically ventilated. Normally, systolic blood pressure is slightly lower during inspiration than expiration due to the change in intrathoracic pressure. Pulsus paradoxus is a phenomenon in which the difference in systolic blood pressure (BP) between inspiration and expiration is more than 10 ...
متن کاملPulsus paradoxus in a patient with tricuspid atresia and hypoplastic right heart.
Increased inspiratory right ventricular filling with a consequent shift of the ventricular septum to the left, thereby decreasing left ventricular filling, has been suggested as a mechanism of pulsus paradoxus. We recently saw a patient with tricuspid atresia and hypoplastic right ventricle who developed pulsus paradoxus. His course may help clarify the contribution of this mechanism.
