STE limited to aVR is due to diffuse subendocardial ischemia, but what of STE in both aVR and V1? The additional ST Elevation in V1 is not usually seen with diffuse subendocardial ischemia, and suggests that something else, like STEMI from LAD occlusion, could be present. Was this: 1) ACS with ischemia and spontaneous reperfusion?

Precordial ST depression may be subendocardial ischemia or posterior STEMI. I have warned in the past that one must think of other etiologies of ischemia when there is tachycardia. Whether it is subendocardial ischemia or posterior STEMI, if you cannot get it to resolve, you must activate the cath lab. There is no ST elevation.

However, an echocardiogram is a different test, also conducted for heart activity. An electrocardiogram is a machine used to record the heart's electrical activity. Electrocardiogram, echocardiogram, and some other tests are done for patients with cardiac arrest. ECG and EKG refer to the same thing.

His response: “subendocardial ischemia. Smith : It should be noted that, in subendocardial ischemia, in contrast to OMI, absence of wall motion abnormality is common. See this case: what do you think the echocardiogram shows in this case? Anything more on history? POCUS will be helpful.” J Electrocardiol 2013;46:240-8 2.

An initial electrocardiogram (ECG) is provided below. A rapid echocardiogram was performed, revealing an ejection fraction of 20% with thinning of the anterior-apical walls. His current medication regimen includes apixaban, carvedilol, perindopril, spironolactone, torasemide, dapagliflozin, amiodarone, and ivabradine.

The ECG in the chart was read as "no obvious ST changes," (even though no previous ECG was available) and the formal read by the emergency physicians was: "ST deviation and moderated T-wave abnormality, consider lateral ischemia." When the ischemia is resolved, the wall motion may completely recover, or there may be persistent stunning.

This may result in ischemia (lack of oxygen to the heart muscle), causing parts of the heart to weaken and enlarge. Echocardiogram An echocardiogram uses sound waves to produce a detailed image of the heart, allowing doctors to see the size of the heart chambers and how well the heart is pumping blood.
