A 36-year-old male comes with a 2-day history of chest pain. The pain has been continuous and does not change with activity. Vital signs show normal BP, mild tachycardia and tachypnea, and an oxygen saturation of 90% on room air. Cardiopulmonary exam is normal. An ECG shows a rate of 106 beats/min, left axis detion, left ventricular hyperophy, PR depression, and T wave inversions in V2 to V5. Troponin and CPK-MB are minimally elevated. What is the most likely diagnosis.
Correct Answer: Pericarditis
Description: Option A: Pulmonary embolism= Ruled out because PE ECG findings are S1Q3T3/Sinus tachycardia Option C: PR segment depression = Atrial myocardium damage T wave inversion - Ventricular myocardium damage This is talking about diffuse damage in the hea. Option D: ECG of unstable angina= ST normal Sometimes ST | T wave inversion & hemodynamic parameters are normal so it unlikely to be unstable angina.
