Acute Pericarditis 286

Introduction to Clinical Electrophysiology and the ECG

On this page, we present acute pericarditis as auscultated at Erb's Point. Murmurs are caused by turbulent blood flow across incompetent or stenotic valves. In contrast, a pericardial friction rub is caused by the rubbing together of two surfaces of the pericardial sack. The pericardial friction rub has three parts; a systolic component, an early diastolic component and a late diastolic component. The first and second heart sounds are obscured by the rubbing sounds. In the anatomy video you can see the yellow fluid accumulation around the heart caused by an inflamed pericardial sack.
