What is the differential of this very unusual ECG?

This ECG is from a young male who presented with a gun shot wound to the head.

This ECG shows tall peaked T waves and short QT. Potassium and calcium levels were normal. These findings are unusual but the cause may have been intracranial haemorrhage.

An ECG sent to me with concern for hyperacute T-waves

This ECG is from a woman in her 70s who presented with sudden nausea, diaphoresis and brief syncope.

This ECG shows subtle concave ST elevation in inferior leads and V4-6. The angiogram was normal, troponins negative and echo showed no wall motion abnormality. The most likely cause was a normal variant.

Elderly with Paced Rhythm, Possible Ischemic symptoms, and an Equivocal Smith Modified Sgarbossa ECG

This ECG is from a woman in her 80s who presented with a couple of days of shortness of breath, weakness and diaphoresis.

This ECG shows ventricular paced rhythm with concordant ST elevation V5-6 and concordant ST depression in V3. The cause was an occlusion of the circumflex.

Acute Chest pain in a 50-something, and a “Normal” ECG

This ECG is from a man in his 50s who presented with acute chest pain.

This ECG shows anterior ST elevation with hyperacute T waves. The cause was a 100% proximal LAD occlusion.

5 Cardiologists said this is not a STEMI. But was it an OMI?

This ECG is from a man in his 50s who presented with waxing and waning chest pain starting at rest.

This ECG shows ST elevation V1-5, I, II and aVL with reciprocal depression in III. The cause was an anterior MI.

The ECG was correct. The angiogram was not.

This ECG is from a man in his 70s who presented with chest pain and nausea on a background of previous MI.

This ECG shows sinus rhythm with PVCs and subtle ST elevation in I, aVL and V2 and reciprocal ST depression in III and aVF. Angiogram was negative. The most likely cause was a brief LAD occlusion that spontaneously reperfused.

How does acute left main occlusion present on the ECG? Case 2

This ECG is from a young woman who presented with sudden pulmonary oedema. This ECG was recorded just before she arrested.

This ECG shows sinus tachycardia, RBBB, LAFB and ST elevation in V2-6, I and aVL. The cause was a 100% left main occlusion.

In the ECGquest archives, this ECG has been tagged with: - Chest pain 12-Lead ST elevation in aVR ST elevation in V1 Widespread ST depression Left main occlusion Dr Smith's ECG Blog CC BY-NC
How does acute left main occlusion present on the ECG?

This ECG is from a woman in her 50s who presented with 3 days of intermittent chest pain that became worse on the day of presentation, with diaphoresis and radiation to the left arm, as well as abdominal pain.

This ECG shows widespread ST depression with ST elevation in aVR and V1-2, due to a 100% left main occlusion.

A young woman with altered mental status and hypotension: Case 2

This ECG is from a patient of unknown age who presented with sudden chest pain and shortness of breath.

This ECG shows domed inverted T waves V1-3, consistent with acute right heart strain caused by Pulmonary Emboli.

A young woman with altered mental status and hypotension

This ECG is from a woman in her 30s who presented with altered mental status and syncope. She was hypotensive and tachycardic.

This ECG shows sinus tachycardia with concave ST segments and domed inverted T waves V1-3, consistent with acute right heart strain caused by large bilateral Pulmonary Emboli.

In the ECGquest archives, this ECG has been tagged with: - 12-Lead Electrical interference artefact Dr Smith's ECG Blog CC BY-NC
What are all these little spikes?

This ECG is from an elderly woman who presented after a fall.

This ECG shows frequent artefact spikes due to a bladder stimulator implanted for her neurogenic bladder.

OMI Confirmed by POCUS Echo in a 50 year man

This ECG is from a man in his 50s who presented with intermittent epigastric burning pain for 4 days that had become constant that morning.

This ECG shows ST elevation in aVL, I and V2-4 with reciprocal ST depression inferiorly. POCUS showed severe hypokinesis of the anterior wall. The cause was a large anterior MI.
