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. No ischemic ST changes.

The ECG shows sinus tachycardia with RBBB and LAFB, without clear additional superimposed signs of ischemia. ECG of pneumopericardium and probable myocardial contusion shows typical pericarditis Male in 30's, 2 days after Motor Vehicle Collsion, complains of Chest Pain and Dyspnea Head On Motor Vehicle Collision.

There is sinus tachycardia. Sinus tachycardia, which exaggerates ST segments and implies that there is another pathology. I have always said that tachycardia should argue against acute MI unless there is cardiogenic shock or 2 simultaneous pathologies. PR depression, which suggests pericarditis 4.

Colchicine did not prevent atrial arrhythmia recurrence at 2 weeks (31% versus 32%; hazard ratio [HR], 0.98 [95% CI, 0.59–1.61];P=0.92) Postablation chest pain consistent with pericarditis was reduced with colchicine (4% versus 15%; HR, 0.26 [95% CI, 0.09–0.77];P=0.02)

He has a family history concerning for arrhythmia. Given the circumstances of his car crash, we presume it was due to an underlying arrhythmia.

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.

I completely agree with Dr. Nossen that in this patient with new CP and sinus tachycardia with LAHB — that the T waves in each of the inferior leads are hyperacute ( ie, clearly disproportionately "bulky" given size of the QRS in these leads ). — and which other patient(s) need to be seen as soon as possible to figure out what is going on?
