This is a value typical for a large subacute MI, n ormal value 48 hours after myocardial infarction is associated with Post-Infarction Regional Pericarditis ( PIRP ). Sinus tachycardia has many potential causes. This is especially true for the elderly patient with sinus tachycardia. What is the cause of the sudden tachycardia?

An Initial ECG was performed: Initial ECG: Sinus tachycardia with prolonged QT interval (QTc of 534 ms by Bazett). She was admitted to the ICU where subsequent ECGs were performed: ECG at 12 hours QTc prolongation, resolution of T wave alternans ECG at 24 hours Sinus tachycardia with normalized QTc interval. 2022 Jul;27(4):e12939.

These latter findings are typical of pericarditis, but pericarditis never has reciprocal ST depression. Usually with pericarditis and myocarditis — hyperacute T waves (HATW) are not present. NOTE #1: Sinus tachycardia is not usually seen in an uncomplicated acute MI. This is OMI until proven otherwise.

The ECG shows sinus tachycardia, a narrow, low voltage QRS with alternating amplitudes, no peaked T waves, no QT prolongation, and some minimal ST elevation in II, III, and aVF (without significant reciprocal STD or T wave inversion in aVL). It is difficult to tell if there is collapse during diastole due to the patient’s tachycardia.
