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.

The ECG shows sinus tachycardia with RBBB and LAFB, without clear additional superimposed signs of ischemia. Hopefully a repeat echocardiogram will be performed outpatient. Other Arrhythmias ( PACs, PVCs, AFib, Bradycardia and AV conduction disorders — potentially lethal VT/VFib ). Chest trauma was suspected on initial exam.

ECG Blog #412 — Is Cardiac Cath Indicated?

Ken Grauer, MD

My written interpretation on a tracing such as this one would read, "Marked LVH and 'strain' and/or ischemia — with need for clinical correlation." BOTTOM LINE: ECG changes of LV "strain" and/or ischemia that we see on today's initial ECG — were not present 9 years earlier. WPW Cardiac arrhythmias ( including AFib ).

There is no evidence of infarction or ischemia. Later, he underwent a formal echocardiogram: Very severe left ventricular enlargement (LVED diameter 7.4 There is a large peaked P-wave in lead II (right atrial enlargement) There is left axis deviation consistent with left anterior fascicular block.

Dr. Smith's ECG Blog

An echocardiogram was done. These include ( among others ) — acute febrile illness — variations in autonomic tone — hypothermia — ischemia-infarction — malignant arrhythmias — cardiac arrest — and especially Hyperkalemia. Other Arrhythmias ( PACs, PVCs, AFib, Bradycardia and AV conduction disorders — potentially lethal VT/VFib ).
