A 25-year old patient with a history of recent respiratory tract infection complains of severe chest pain at rest. The ECG of the patient is given. The most probable diagnosis of the patient is?: (A) Acute MI, (B) Prinzmetal angina, (C) Takotsubo cardiomyopathy, (D) Acute pericarditis
Answer is D. The history points to a recent viral infection that could contribute to the development of pericarditis. Acute Pericarditis -Most common cause of pericarditis is idiopathic or viral. -ECG findings: Hea rate= 75 bpm Axis= normal PR interval= 0.16 sec QRS= 0.08 sec QT= 400 msec Uniform ST segment elevation - Concave upwards (RED) in all the leads ST segment depression (BLUE) in aVR seals the diagnosis of pericarditis.
