What are the possible mechanisms of simultaneous Inferior and Anterior STEMI?

Dr. S. Venkatesan MD

RCA-dependent LAD circulation through collaterals 3. True bifurcation STEMI with static thrombus (Carinal trapping of thrombus ,Coronary Lerish sydrome ) 4. Embolic STEMI with showers of emboli into both LCX and LAD Simultaneous or sequential Anterior and Inferior STEMI 5. Wrap around LAD true Global MI 2.

Large Transmural STEMI with Myocardial "Rupture" of Ventricular Septum

Dr. Smith's ECG Blog

Thus, this is both an anterior and inferior STEMI. How old is this antero-inferior STEMI? Although acute anterior STEMI frequently has narrow QR-waves within one hour of onset (1. Armstrong et al.)], the presence of such well developed anterior Q-wave suggests completed transmural STEMI. Circulation 1993;88(3):896-904.

Subacute AnteroSeptal STEMI, With Persistent ST elevation and Upright T-waves

Dr. Smith's ECG Blog

Thus, this is BOTH an anterior and inferior STEMI in the setting of RBBB. How old is this antero-inferior STEMI? Although acute anterior STEMI frequently has narrow QR-waves within one hour of onset (1. the presence of such well developed, wide, anterior Q-wave suggests completed transmural STEMI. Could it be acute (vs.

Why the sudden shock after a few days of malaise?

Dr. Smith's ECG Blog

This is a value typical for a large subacute MI, n ormal value 48 hours after myocardial infarction is associated with Post-Infarction Regional Pericarditis ( PIRP ). As already mentioned, this patient could have post-infarction regional pericarditis from a large completed MI. Sinus tachycardia has many potential causes.

Occlusion myocardial infarction is a clinical diagnosis

Dr. Smith's ECG Blog

Recall from this post referencing this study that "reciprocal STD in aVL is highly sensitive for inferior OMI (far better than STEMI criteria) and excludes pericarditis, but is not specific for OMI." Circulation , 130 (25). St depression in lead AVL differentiates inferior st-elevation myocardial infarction from pericarditis.

Initial Reperfusion T-waves, Followed by Pseudonormalization. Diagnosis?

Dr. Smith's ECG Blog

cm diameter in the apex The presence of thrombus led the clinicians to state that this was a "late presentation STEMI." It does take some time for thrombus to form, but the EKG and the troponin profile show that this was NOT a late presentation STEMI. of AMI patients and is often preceded by postinfarction regional pericarditis (PIRP).

Opiate overdose, without chest pain or shortness of breath. Cognitive dissonance.

Dr. Smith's ECG Blog

Of course this depends on many factors: 1) duration of occlusion, 2) whether full or near occlusion with zero flow or some flow -- the flow in the artery is the critical factor, measured by "TIMI" flow, 3) presence of collateral circulation and others. Pericarditis would be even more unlikely in someone without chest pain.
