As is also emphasized often in this ECG Blog — spontaneous reperfusion of the "culprit" artery is common — and, IF this occurs before a 2nd ECG is done, ST-T wave changes may "look better" ( See References to related Blog posts below ). ECG Blog #294 — Reviews how to tell IF the " culprit " artery has reperfused.

As opposed to polymorphic VT that by definition is irregularly irregular — monomorphic VT is usually a fairly ( if not completely ) regular rhythm ( See ECG Blog #231 for the various forms of VT ). BOTTOM Line: The ECG in Figure-4 shows an extensive infero-postero-lateral STEMI. R wave progression is not normal.

For full discussion of this case — See ECG Blog #351 — == The ECG in Figure-1 — was obtained from a previously healthy older man who contacted EMS ( E mergency M edical S ervices ) because of "chest tightness" that began ~1 hour earlier. ECG Blog #205 = The Systematic Approach I favor. . =

PEARL # 3: While not 100% predictive — seeing a significant negative component to the P wave in these leads ( as per the YELLOW arrows in Figure-2 ) — suggests that the V1,V2 electrodes may be placed 1 or 2 interspaces too high on the chest ( See ECG Blog #274 — for more on too high placement of the V1,V2 electrode leads ).

Prompt cath is therefore advised if the post-ROSC shows an acute STEMI. I i llustrate the ECG finding of T-QRS-D below in Figure-3 , which I've excerpted from My Comment in the November 14, 2019 post in Dr. Smith's ECG Blog. To Emphasize: The phenomenon of T-QRS-D is not needed in today's case to recognize the acute STEMI.

I favor starting with the long lead II rhythm strip — by use of the P s, Q s, 3 R Approach ( See ECG Blog #185 for more on the Ps, Qs, 3Rs ).

Despite the absence of significant coronary stenosis on her post-arrest cath — the ECG in Figure-1 is clearly diagnostic of an extensive anterolateral STEMI ( presumably from acute LAD [ L eft A nterior D escending ] coronary artery occlusion). The rhythm in ECG #1 is regular and supraventricular at a rate of ~75/minute. What is T-QRS-D?
