“…The classic physical exam findings of CP are helpful but inconsistently present. These include a prominent “y” descent of the jugular venous pulse ( 5 ); Kussmaul’s sign (failure of venous collapse or venous pressure increase during inspiration), which may also be present in RV failure, pulmonary embolism, and RV infarct ( 6 ); pulsus paradoxus, defined as a fall in systolic blood pressure >10 mm Hg during inspiration; and a pericardial knock, described as a high-pitched sound during ventricular filling “snapping” in character sometimes confused with an S3 ( 7 ).…”

“…The precordial knock, a protodiastolic sound, corresponds to the abrupt cessation of ventricular filling and is pathognomonic of pericardial constriction [48]. The electrocardiogram may show low-voltage QRS complexes and an interventricular conduction delay.…”

Pericarditis (inflammation of the pericardium) may be caused by infectious agents, autoimmune disorders, metabolic conditions, or malignancy, or it may be a complication of drug therapy, trauma, cardiac surgery, or smallpox vaccination. Diagnosis, based on clinical findings, electrocardiographic changes, chest radiograph, and ultrasound, may be confirmed as appropriate by pericardiocentesis. Although contemporary imaging technologies, such as computed tomography and magnetic resonance imaging, are useful, echocardiography remains the simplest and most expeditious noninvasive tool to assess inflammatory and infectious diseases of the pericardium. Although contemporary management of pericardial disease remains relatively unchanged, reports of innovative approaches to the management of pericardial effusion include the installation of intrapericardial thrombolytic agents to facilitate drainage of purulent effusions or balloon pericardiotomy for recurrent effusions. Both offer potential alternatives to the surgical pericardial window.
