Acute Pericarditis 697
Virtual Auscultation
The patient's position is sitting leaning forward.
Lesson
Acute pericarditis murmurs are generated by turbulent blood flow across incompetent or stenotic valves. In contrast, a pericardial friction rub is produced 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.
This murmur is auscultated at Erb's Point.
In the cardiac animation video, observe the yellow fluid accumulation around the heart caused by an inflamed pericardial sack.
