There is sinus bradycardia with one PVC. MINOCA: Myocardial Infarction in the Absence of Obstructive Coronary Artery Disease). pulmonary embolism, sepsis, etc.), Coronary thrombosis or embolism can result in MINOCA, either with or without a hypercoagulable state. She then had a 12-lead: What do you think?

PVCs N ot generally considered abnormal ECG findings: Isolated PAC, First Degree AV Block, Sinus bradycardia at a rate of 35-45, and Nonspecific ST-T abnormalities (even if different from a previous ECG). Thus, if there is documented sinus bradycardia, and no suspicion of high grade AV block, at the time of the syncope, this is very useful.

There is also STE in V1 which is diagnostic of right ventricular OMI in this situation , and partly explains the syncope and hypotension (along with the bradycardia). Here it is annotated in red: Our extremely smart radiologist, Gopal Punjabi , assures me that this finding can only be due to myocardial infarction, not myocarditis.

Within ten minutes, she developed bradycardia, hypotension, and ST changes on monitor. If this were OMI, I would favor proximal RCA culprit (since that commonly produces inferolateral changes and occasionally produces anterior HATW from RV infarct ), but LAD is also possible. Bradycardia and heart block are very common in RCA OMI.
