Pathophysiology - hemodynamic effects of pericardial disease result entirely from interference with cardiac filling - low CO with high CVP = pericardial, myocardial, valvular, pulmonary vascular disease - understanding the pathophysiology of disordered cardiac filling helps distinguish between cardiac tamponade , constrictive pericarditis , and effusive-constrictive pericarditis - …

Characteristric CVP findings: classically, a sawtooth "M" or "W" configuration of a raised CVP. Chapter 18 (Pericardial Constriction and Cardiac Tamponade, p.313 ) from Jonathan Marks' Atlas of Cardiovascular Monitoring (1993) has an entire section on the CVP trace in cardiac tamponade. The waveform patterns below were abducted from Marks and severely …

CVP tracing in tamponade • V wave: » Passive filling of the RA during RV systole • Y descent: » TV opens, passive RA emptying ... » Passive emptying of RA is dependent on pressure difference between RA and RV: in tamponade, the pericardial pressure takes over all other diastolic pressures (= loss of Y descent) Cardiac tamponade: echo ...
Cardiac Tamponade - StatPearls - NCBI Bookshelf
https://www.ncbi.nlm.nih.gov/books/NBK431090/
Cardiac tamponade is a medical emergency that takes place when abnormal amounts of fluid accumulate in the pericardial sac compressing the heart and leading to a decrease in cardiac output and shock. This activity describes the evaluation and management of cardiac tamponade and reviews the role of the interprofessional team in improving care for …

Cardiac tamponade: Pulsus paradoxus - OpenAnesthesia
https://www.openanesthesia.org/cardiac_tamponade_pulsus_paradoxus/
Cardiac tamponade is caused by an increased amount of fluid in the pericardial sac, which compresses the heart. To a point, the body can adapt by increased adrenergic tone which in turn increases systemic venous pressure and heart rate. This increase in pressure prevents the heart chambers from collapsing.
Abnormal central venous pressure waveform patterns

In pericardial constriction, the CVP will be raised, and the x and y descent is steep and abrupt. This contrasts with cardiac tamponade where the y -descent is prolonged. Previous chapter: Interpretation of the central venous pressure waveform
Cardiac Tamponade – Pocket ICU
http://pocketicu.com/index.php/2016/10/15/cardiac-tamponade/
In cardiac tamponade, the pericardial space is open and transmits respiratory variation in intrathoracic pressure to the heart. In contrast, patients with constrictive pericarditis have a thickened, rigid pericardium which prevents the normal inspiratory decrease in intrathoracic pressure from being transmitted to the heart.
