Sometimes a patient is fortunate to have a cardiac arrest

Dr. Smith's ECG Blog

Smith comment: The patient was lucky to have a cardiac arrest. By undergoing an arrest, providers became aware of his OMI which had not been noticed on his diagnostic ECG, and he thus has a chance at some myocardial salvage. Had he not had one, he would have sat in the waiting room until his entire myocardium at risk infarcted.

Cardiac arrest: even after the angiogram, the diagnosis is not always clear

Dr. Smith's ECG Blog

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?

Cardiac Arrest, acute ST elevation and depression superimposed on LVH, but NOT due to ACS

Dr. Smith's ECG Blog

There is profound LVH with anterolateral ST elevation and reciprocal ST depression in II, III, aVF, and ST depression in V5 and V6 that could all be secondary to LVH or could represent ischemia superimposed on the repolarization abnormalities of LVH: note that wherever there is ST depression, it is associated with a very high voltage R-wave.

VF arrest at home, no memory of chest pain. Angiography non-diagnostic. Does this patient need an ICD? You need all the ECGs to know for sure.

Dr. Smith's ECG Blog

This was interpreted by the treating clinicians as not showing any evidence of ischemia. Echocardiogram showed LVEF 66% with normal wall motion and normal diastolic function. However, he did not remember much from the day of the arrest. He was intubated in the field and sedated upon arrival at the hospital.

However, an echocardiogram is a different test, also conducted for heart activity. Cardiac arrest Cardiac arrest is a medical emergency in which the heart stops pumping blood to the body. Electrocardiogram, echocardiogram, and some other tests are done for patients with cardiac arrest.

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.

90 year old with acute chest and epigastric pain, and diffuse ST depression with reciprocal STE in aVR: activate the cath lab?

Dr. Smith's ECG Blog

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.
