The ECG in Figure-1 — was obtained from a middle-aged woman with positional tachycardia and diaphoresis with change of position from suprine to sitting. Although CP ( C hest P ain ) was not a prominent symptom — ACS ( A cute C oronary S yndrome ) was suspected from the chest lead T wave inversion seen on this ECG. WHY — or Why Not?

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 ).

Below is old and then new ECG (old on top; new below). Both ECGs have normal sinus rhythm, normal conduction and normal voltages. Because of the ECG changes in a patient with chest pain, and with inferolateral hypokinesis on POCUS, the cath lab was activated. What do you think? But do they represent acute coronary occlusion?

What do you think of the ECG, and does it matter? I sent this to the Queen of Hearts So the ECG is both STEMI negative and has no subtle diagnostic signs of occlusion. 2] This is because, contrary to Bayesian reasoning, the STEMI paradigm is named after and defined by one part of one test: ST elevation on ECG. But only 6.4%

The first EKG is from 2:30 PM on the day of presentation to the ER. My eyes would bulge within a second of viewing this ECG. I texted this to our group "EKG Nerdz," asking "Do you think that anyone could miss this?" No repeat ECG was recorded. The EKG was not repeated until 7 AM the next morning, about 16 hours later.

Below are serial ECGs focusing on the inferior leads and aVL. First, what’s the interpretation of each ECG on its own? #1 2 Normal ECG #3. 2 Normal ECG #3. But 90 minutes later troponin returned at 70ng/L (normal <26 in males and <16 in females), and a repeat ECG was done (ECG#2) for recurring chest pain.

All initial ECGs were labeled ‘normal’ or ‘otherwise normal’ by the computer interpretation, and below are the ECGs with the final cardiology interpretation. 1-3] But these studies were very short duration and used cardiology interpretation of ECGs or emergent angiography rather than patient outcomes.
