At physical exam rounds today, we reviewed Pericarditis.
Clinical presentation: usually a sudden onset of retrosternal chest pain with a pleuritic component to it, often relieved by sitting up. You may hear a pericardial rub - this is classically described as a triphasic high-pitched sound. The 'tri' refers to 1. atrial systole, 2. ventricular systole, and 3. ventricular diastole.
ECG: may show diffuse, concave ST elevations that do not fit any particular vascular territory. PR depression is also seen.
Treatment: In most cases of idiopathic pericarditis, high dose NSAIDS are effective. Steroids and colchicine also may have a role.
Here is a review article on the topic.
