Dynamic OMI ECG. Negative trops and negative angiogram does not rule out coronary ischemia or ACS.

Another ECG was recorded after the nitroglycerine and now without pain: All findings are resolved. This confirms that the pain was ischemia and is now resovled. The history is concerning ( This patient was awakened from sleep by chest pain that persisted for several hours — on a background of intermittent CP in recent weeks ).

There was no chest pain. V1 and V2 are probably placed too high on the chest given close morphological similarity to aVR. More detailed reviews of subendocardial ischemia, as well as acute ECG patterns that breach the typical presentation, can be found here: [link] [link] Imaging revealed no acute head, or spinal, injuries.

A 60-something awoke with 10/10 crushing chest pain. I would expect TIMI-3 flow (normal flow, no persistent ischemia) with a culprit in the RCA (or possibly Circumflex). The angiogram showed an open artery with 95% stenosis and thrombosis and it was stented. He walked in to triage.

A 70-something female with no previous cardiac history presented with acute chest pain. She awoke from sleep last night around 4:45 AM (3 hours prior to arrival) with pain that originated in her mid back. She stated the pain was achy/crampy. Over the course of the next hour, this pain turned into a pressure in her chest.

A mid 60s woman with history of hypertension, hyperlipidemia, and GERD called 911 for chest pain. It is also NOT the clinical scenario of takotsubo (a week of intermittent chest pain).

But the symptoms returned with similar pattern – provoked by exertion, and alleviated with rest; except that on each occasion the chest pain was a little more intense, and the needed recovery period was longer in duration. It should be known that each category can easily manifest the generic subendocardial ischemia pattern.

There is broad subendocardial ischemia as demonstrated by STE aVR with concomitant STD that almost appears appropriately maximal in Leads II and V5. There is LBBB-like morphology with persistent patterns of subendocardial ischemia. This is the initial ECG: The QRS is widened with a regular cadence, and there are no discernable P waves.

No chest pain. Normally, concavity in ST segments suggests absence of anterior ischemia (though concavity by itself is not reassuring - see this study ). Later on during the night of his admission he had a short episode of chest pain that resolved with sublingual nitroglycerin. His vitals were initially normal.

Written by Pendell Meyers and Peter Brooks MD A man in his 30s with no known past medical history was reported to suddenly experience chest pain and shortness of breath at home in front of his family. Thus, this apparently is Aslanger's Pattern (inferior OMI with single lead STE in lead III, with simultaneous subendocardial ischemia).

Case An elderly patient had acute chest pain and 911 was called. For this analysis, ACO was defined as angiographic evidence of coronary thrombosis with peak cardiac troponin-I (cTn-I) at least 10 ng/mL or cTn-T ≥ 1 ng/ mL. It is important for cardiologists to realize that a paramedic may see something they do not.

He denied chest pain. Time 7 hours lead reversal There is limb lead reversal (QRS in I and aVL are now inverted), but nevertheless one can see that the ischemia appears to have resolved. Negative trops and negative angiogram does not rule out coronary ischemia or ACS. Next day, with K = 4.6 The evidence of OMI is gone.

But this is most common when there is prolonged ischemia, and this patient had the fastest reperfusion imaginable!
