Prompt cath is therefore advised if the post-ROSC shows an acute STEMI. The rhythm is regular — at a rate just over 100/minute = sinus tachycardia ( ie, the R-R interval is just under 3 large boxes in duration ). Continuing with assessment of ECG #1 in Figure-2: The rhythm is sinus tachycardia at ~110/minute.

Background Early ventricular tachycardia/fibrillation (VT/VF) in patients with ST-elevation myocardial infarction (STEMI) has higher morbidity and mortality. This study examines gender-differentiated risk factors and underlying mechanisms for early onset VT/VF in STEMI. vs. 61.0 ± 13.0 vs. n  = 46, L5: 4.3 ± 9.9%, P  = 0.016).

This is ischemic ST depression, and could be due to increasing tachycardia, with a heart rate over 130, but that is unlikely given that the patient is now complaining of crushing chest pain and that there was tachycardia all along. There is widespread ST depression. Figure-1: Comparison of the first 2 ECGs in today's case.

The ECG shows obvious STEMI(+) OMI due to probable proximal LAD occlusion. This progressed to electrical storm , with incessant PolyMorphic Ventricular Tachycardia ( PMVT ) and recurrent episodes of Ventricular Fibrillation ( VFib ). The below ECG was recorded. He required multiple defibrillations within a period of a few hours.

Here, I do not see OMI (although the ECG is falsely STEMI positive with just over 1 mm STE in V1 and about 2.5 This is sinus tachycardia (rhythm) with complete heart block (AV node function) with ventricular escape rate just below 30. Never forget that sinus tachycardia is the scariest arrhythmia. What do you think?

The attending crews were concerned for SVT with corresponding ischemic hyperacute T waves (HATW) and subsequently activated STEMI pre-hospital. 2] But there is also Sinus Tachycardia! Then, three minutes later… Crews activated STEMI as she deteriorated into PEA arrest. Closer inspection will show that it is Sinus, after all.
