ECG Blog #435 — Did Cath Show Acute Ischemia?

Ken Grauer, MD

That said — the ECG in Figure-1 should prompt the following considerations: The symmetric chest lead T wave inversion in ECG #1 could be a sign of coronary disease, potentially with acute ischemia. During my decades of working with residents when hospital Attending — by far, the most commonly overlooked vital sign was respiratory rate.

Revascularization Strategies in Stable Coronary Artery Disease: ISCHEMIA Trial Insights

Cardiology Update

In the ISCHEMIA (International Study of Comparative Health Effectiveness with Medical and Invasive Approaches) trial, researchers examined the risk of ischemic events in patients with stable coronary artery disease. years, with 57.1% occurring within 30 days after CABG.

Impact of Intensity of Vascular Care Preceding Major Amputation Among Patients With Chronic Limb-Threatening Ischemia

Circulation: Cardiovascular Interventions

BACKGROUND:Lower-limb amputation rates in patients with chronic limb-threatening ischemia vary across the United States, with marked disparities in amputation rates by gender, race, and income status. 0.98];P=0.019), and those who received care at a safety-net hospital (odds ratio, 0.87 [95% CI, 0.78–0.97];P=0.012) Mean age, 76.6

Electrocardiographic Findings in Diffuse Subendocardial Ischemia

The New England Journal of Medicine

At the hospital, left main coronary-artery stenosis was seen on angiography (shown in a video). In a 57-year-old man with chest pain, an ECG obtained by EMS showed widespread ST-segment depressions.

Resuscitated from ventricular fibrillation. Should the cath lab be activated?

Dr. Smith's ECG Blog

The ECG shows severe ischemia, possibly posterior OMI. But cardiac arrest is a period of near zero flow in the coronary arteries and causes SEVERE ischemia. It takes time for that ischemia to resolve. The patient was brought to the ED and had this ECG recorded: What do you think? And what do you want to do?

An undergraduate who is an EKG tech sees something. The computer calls it completely normal. How about the physicians?

Dr. Smith's ECG Blog

This EKG is diagnostic of transmural ischemia of the inferior wall. If it is angina, lowering the BP with IV Nitroglycerine may completely alleviate the pain and the (unseen) ECG ischemia. Transmural ischemia (as seen with the OMI findings on ECG) is not very common with demand ischemia, but is possible. Smith SW.

His confusion progressively dissipated enroute to the hospital. Many of the changes seen are reminiscent of LVH with “strain,” and downstream Echo may very well corroborate such a suspicion, but since the ECG isn’t the best tool for definitively establishing the presence of LVH, we must favor a subendocardial ischemia pattern, instead.
