This ECG shows inferior ST elevation with Q waves in III and reciprocal ST depression in aVL, most likely caused by an acute inferior MI.

This ECG is from a man in his 60s who presented with chest pain for 48h with diaphoresis.

This ECG shows inferior ST elevation with reciprocal depression in aVL and I. ST depression in V2-4. Deep Q waves inferior leads and tall R waves V1-3. The cause was a completed infarction with 2 likely culprits (RCA and circumflex).

This ECG is from a man in his 60s who presented with chest pain radiating to the back and nausea/vomiting. He had a history of previous MI and stents.

This ECG shows inferior ST elevation (straightened ST segments) without reciprocal changes, with terminal QRS distortion in inferior leads. The cause was an inferior MI with some posterior involvement.

This ECG is from a patient of unknown age who presented with a syncopal episode and vague chest pain. This was the second ECG taken 24 min later.

This ECG shows subtle inferior ST elevation with reciprocal ST depression in aVL. The cause was a 100% distal RCA occlusion.

This ECG is from an ECG from a patient of unknown age, recorded just before the patient went into VF arrest.

This ECG shows massive concave ST elevation in inferior and lateral leads with ST depression in V2. There is also first degree heart block. The most likely cause was an acute MI.

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.

This ECG is from an elderly woman who presented with 2 hours of chest pain on a background of multiple stents, a pacemaker, stroke and COPD.

This ECG shows paced rhythm with excessively discordant ST segments (modified Sgarbossa positive). The cause was a 95% thrombotic lesion of the RCA.

This ECG is from a man in his 40s who presented with 1 hour of chest pain.

This ECG shows sinus arrhythmia with slight ST depression in I and aVL. Serial ECGs showed evolution to an inferior STEMI, due to a 100% RCA occlusion.

This ECG is from a woman in her 70s who presented with acute chest pain and dyspnoea on a background of hypertension and congestive heart failure.

This ECG shows inferior ST elevation with an abnormally wide QRS (intraventricular conduction delay). The cause was an acute inferior MI.

This ECG is from a patient of unknown age who had recurrent presentations for shortness of breath due to asthma.

This ECG shows subtle ST elevation in III with reciprocal change in aVL. The cause was inferior MI.

This ECG is from a middle aged male who presented with chest pain. He was pain free at the time of this initial ECG.

This ECG shows subtle inferior ST elevation with reciprocal change in aVL. The cause was a large inferior infarct.

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

This ECG shows ST elevation in inferior leads with reciprocal changes in aVL and I
