The ECG and long lead II rhythm strip in Figure-1 — was obtained from a COVID positive patient with persistent tachycardia not responding to Diltiazem. Figure-1: The initial ECG — obtained from a patient with persistent tachycardia. ( To improve visualization — I've digitized the original ECG using PMcardio ).

This is the result for this ECG, from MDcalc.com : The most accurate cutpoint is 18.2. And she learned it well: She is not highly confident, but she does diagnose OMI. Here is a similar case from Pendell: This ECG was handed over at triage. A value above 18.2 (LAD A value above 19 is about 97% specific for LAD OMI.

The following ECG was recorded. The presenting ECG shows SR with narrow QRS complexes. There is some upwards concave ST segment elevation in the inferior leads with what seems to be well formed J-waves. First troponin I returned 3174 ng/l, at which point a repeat ECG was ordered. Not much difference from 1st ECG.

More pertinent to your recent This Week in Cardiology podcast , patients with monomorphic ventricular tachycardia and coronary disease often have a small troponin rise and ST segment changes on their initial post-cardioversion ECG (and have established coronary disease). It is our goal. Thanks for your support. It has been amazing.

Written by Pendell Meyers, with edits from Steve Smith Let's consider this nearly pathognomonic ECG without the clinical context (because sometimes the clinical context will not be as easy as in this case). This ECG is diagnostic of hemodynamically significant acute right heart strain. She was discharged and did well.

Given her reported chest pain, shortness of breath, and syncope, an ECG was quickly obtained: What do you think? The beat-to-beat variation in the QRS complexes (electrical alternans) is a classic ECG finding of a large pericardial effusion or pericardial tamponade. For clarity in Figure-1 — I've reproduced her initial ECG.
