A patient with chest pain that is resolving. Computer interprets ED ECG as completely Normal.

This ECG is from a man in his 60s who presented with resolving chest pain.

This ECG shows hyperacute T waves in V2-4. The cause was an 80% obstruction of the LAD with a large thrombus. An earlier ECG showed ST segment elevation.

A 40-something woman with no medical history presented with 2 days of chest pain

This ECG is from a woman in her 40s who presented with 2 days of chest pain.

This ECG shows widened QRS with delta waves due to Wolff Parkinson White syndrome. This was missed by the computer. There are secondary repolarisation changes.

A 60-something with syncope

This ECG is from a man in his 60s who had a witnessed sudden loss of consciousness and awakening.

This ECG shows widespread ST elevation without reciprocal ST depression. Angiography was normal.

The computer and the cardiologist called this a “Normal EKG”

This ECG is from a woman in her 40s who presented with 'heartburn' overnight and then worsening chest pain 1 hour prior to arrival.

This ECG shows subtle MI with inferior and anterior hyperacute T waves and some reciprocal ST depression in aVL. The cause was a complete occlusion of a wraparound LAD.

Is this new LAD occlusion with ST Elevation superimposed on old QS-wave MI?

This ECG is from a middle aged male who presented with a choking feeling in his throat, on a background of prior anterior STEMI complicated by cardiac arrest, and ICD.

This ECG shows QS waves with ST elevation in anterior leads. The T waves were larger than previous, so he was sent to the cath lab, but angiography was normal.

I was handed this ECG at triage with no information

This ECG is from a man in his 50s who presented with a syncopal event.

This ECG shows comparison to baseline ECGs suggested an old MI with persistent ST elevation (LV aneurysm).

A man in his sixties with chest pain at midnight with undetectable troponin

This ECG is from a man in his 60s who presented with 3 hours of chest pain.

This ECG shows ST elevation and hyperacute T waves in V2 with inferior and lateral ST depression. The cause was acute LAD occlusion.

LBBB. Is there Occlusion MI (OMI)? Is so, which artery is it?

This ECG is from a patient who presented in acute pulmonary oedema.

This ECG shows sinus tachycardia with LBBB and concordant ST depression in inferior leads. There is also excessive discordant ST depression in V6. The cause was a 100% LAD occlusion.

LVH with expected repolarization abnormalities, or acute OMI?

This ECG is from a patient who presented with acute chest pain on a background of diabetes.

This ECG shows LVH and inferior ST elevation with depression in aVL (slight). This was new in comparison to the baseline ECG. The cause was most likely a RCA narrowing.

In the ECGquest archives, this ECG has been tagged with: - Long QT Hypokalemia 12-Lead Dr Smith's ECG Blog CC BY-NC
Potassium and Magnesium: how low is too low?

This ECG is from a woman in her 30s who presented with vomiting, diarrhoea and cough for 2-3 days.

This ECG shows long QTc due to hypokalemia. She was found unresponsive in VF shortly after and required defibrillation.
