Do you recognize this ECG yet? 31724

This ECG is from a man in his 30s who presented with chest pain and RUQ abdominal pain, on a background of type 1 diabetes. His BSL was high.

This ECG shows sinus tachycardia with a wide QRS, R in aVR, coved ST elevation and peaked T waves. The cause was hyperkalemia.

What is the differential of this very unusual ECG? 31675

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.

Patient with Dyspnea. You are handed a triage ECG interpreted as “normal” by the computer. 30500

This ECG is from a dialysis patient who presented with dyspnoea.

This ECG shows subtly peaked T waves and flat ST segments. The cause was hyperkalemia (6.3).

Patient with Dyspnea. You are handed a triage ECG interpreted as “normal” by the computer. ‘Baseline’ ECG 31311

This ECG is from a dialysis patient who presented with diaphoresis and muscle cramps.

This ECG shows subtly peaked T waves and long ST segments causing a long QT interval. The cause was hyperkalemia (6.6) and hypocalcemia.

A patient with cardiac arrest, ROSC, and right bundle branch block (RBBB). 29698

This ECG is from a patient who presented after a PEA arrest with ROSC after intubation and chest compressions.

This ECG shows irregular, slow, wide complex rhythm with peaked T waves due to hyperkalemia.

What will you do for this altered and bradycardic patient? 29169

This ECG is from a woman in her 60s who presented from a nursing home with altered mental status, hypotension, hypoxia and bradycardia.

This ECG shows an irregular rhythm due to second degree AV block with wide QRS and peaked T waves. The cause was hyperkalemia.

The Interventionalist Refuses Angiography, and even to speak to the Emergency Physician 29151

This ECG is from a middle aged patient who presented with chest pain of uncertain duration.

This ECG shows ST elevation in V1 only. This was dynamic on serial ECGs. The cause was a proximal RCA occlusion. The T waves were peaked but the potassium was normal.

This ECG is from a middle aged patient who presented with chest pain of uncertain duration. This was the repeat ECG when pain free

This ECG shows ST elevation in V1 has resolved. This was dynamic on serial ECGs. The cause was a proximal RCA occlusion. The T waves were peaked but the potassium was normal.

The Interventionalist Refuses Angiography, and even to speak to the Emergency Physician – repeat ECG pain free 29334

This ECG is from a middle aged patient who presented with chest pain of uncertain duration. This was the repeat ECG when pain returned.

This ECG shows ST elevation in V1, II, III and aVF with reciprocal ST depression in aVL. The cause was a proximal RCA occlusion. The T waves were peaked but the potassium was normal.

This ECG is from a woman of unknown age who presented with a clotted dialysis shunt. The computer interpretation was 'Normal'.

This ECG shows peaked T waves and flattened ST segments caused by hyperkalemia.

What is the diagnosis? 29042

This ECG is from a patient on dialysis who presented after a fall.

This ECG shows flattened ST segments and peaked T waves due to hyperkalemia.
