Pulsus paradoxus, also paradoxic pulse or paradoxical pulse, is an abnormally large decrease in stroke volume, systolic blood pressure (a drop more than 10 mmHg) and pulse wave amplitude during inspiration. Pulsus paradoxus is not related to pulse rate or heart rate, and it is not a paradoxical rise in systolic pressure.
Pulsus paradoxus: A pulsus paradoxus is an exaggerated decrease in systolic blood pressure during inspiration. It can indicate certain medical conditions in which there is reduced cardiac output, such as cardiac tamponade or constrictive pericarditis. Also known as the Pulse Paradox.
Pulsus paradoxus is a phenomenon in which systolic blood pressure drops by 10 mmHg or more during inspiration. In cardiac tamponade, the pressure within the pericardium is significantly higher, hence decreasing the compliance of the chambers (the capacity to expand/ conform to volume changes).
The pericardium is a double-walled sac around the heart.The inner and outer (visceral and parietal, respectively) layers are normally lubricated by a small amount of pericardial fluid, but the inflammation of pericardium causes the walls to rub against each other with audible friction.
There are five Korotkoff sounds: [7] Phase I: The first appearance of faint, repetitive, clear tapping sounds which gradually increase in intensity for at least two consecutive beats is the systolic blood pressure.
The differential diagnoses of Kussmaul's sign includes constrictive pericarditis, restrictive cardiomyopathy, pericardial effusion, and severe right-sided heart failure. [citation needed]
Purulent Pericarditis; Echocardiogram showing pericardial effusion with signs of cardiac tamponade: Specialty: Cardiology: Symptoms: substernal chest pain (exacerbated supine and with breathing deeply), dyspnea, fever, rigors/chills, and cardiorespiratory signs (i.e., tachycardia, friction rub, pulsus paradoxus, pericardial effusion, cardiac tamponade, pleural effusion)
Beck's triad is a collection of three medical signs associated with acute cardiac tamponade, a medical emergency when excessive fluid accumulates in the pericardial sac around the heart and impairs its ability to pump blood.
