While this ECG is negative for “posterior STEMI”, the resolution of anterior ST depression (accompanied by the troponin elevation) confirms posterior OMI with spontaneous reperfusion. The second opportunity to make the diagnosis and expedite angiography was missed because the ECG never met STEMI criteria and continued to be labeled ‘normal.’

European Heart Journal 38(41):3082-3089; November 1, 2017. And, in cases like the elderly patient with new-onset chest pain presented here — definitive diagnosis of acute STEMI is sometimes deceptively easy. BOTTOM LINE: Despite cardiac pacing — ECG #2 is diagnostic of a very large acute anterior STEMI.

A prehospital STEMI activation was transmitted to the closest PCI center, and 324mg ASA was administered. The attending crews were concerned for an ACS-equivalent of LAD occlusion and initiated a prehospital STEMI activation to the closest PCI center. It’s important to stress the presence of a normal QRS (i.e., 2] Driver, B.

This strongly suggests reperfusing RCA ischemia. Troponins, echocardiogram An echocardiogram showed inferobasilar hypokinesis, further supporting a diagnosis of regional ischemia , likely of the area supplied by the RCA.

2) The STE in V1 and V2 has an R'-wave and downsloping ST segments, very atypical for STEMI. Cardiology was consulted and they agreed that the EKG had an atypical morphology for STEMI and did not activate the cath lab. Smith comment: 1) Brugada ECG may have ST shifts in limb leads as well as precordial leads. Bicarb 20, Lactate 4.2,

PCI mid LCx So this is an OMI (Occlusion Myocardial Infarction), but not a STEMI Echo: Decreased left ventricular systolic performance, mild/moderate. This figure comes from the Diamond T study (all type 1 MI were NSTEMI, not STEMI): Notice that the 6 hour value (far right) is very low for type 2 MI. Angiogram: LM 30% ostial.

S-wave is in V2 = 17 mm S-wave V4 = 9 mm Total = 26 (not greater than 28), so not LVH by the new rule! Nevertheless, it has the look of LVH. Peguero JG et al.

This doesn’t meet STEMI criteria so in the current paradigm there’s no urgency to getting an angiogram. Even though they were passed the 12 hour mark traditionally associated with reperfusion benefits, ongoing ischemia requires emergent angiogram On assessment, the patient appeared uncomfortable, leaning forward in his chair.

ECG met STEMI criteria and was labeled STEMI by computer interpretation. J waves can also be induced by Occlusion MI (5), STEMI mimics including takotsubo and myocarditis complicated by ventricular arrhythmias (6, 7), and subarachnoid hemorrhage with VF (8).

A 12-lead was recorded, showing "STEMI," but is unavailable. Moreover, if you know that catastrophic intracranial hemorrhage can result in an ECG that mimics STEMI, then you know that this patient probably has a severe intracranial hemorrhage. She was BVM ventilated and suctioned. Shortly thereafter, pulses were lost.

50% of LAD STEMI have Q-waves by one hour. Smith : In limb leads, the ST vector is towards lead II (STE lead II STE lead III, which is more likely with pericarditis than with STEMI). There were no other causes of dyspnea apparent and thus we can assume that myocardial ischemia started 6 days prior. See Raitt et al.:
