This ECG is from a man in his 70s who presented with epigastric pain.

This ECG shows LBBB with discordant ST changes that do not quite meet Modified-Sgarbossa criteria. A repeat ECG showed evolution to excessive discordance. The patient went into VF shortly after and died.

This ECG is from a woman in her 40s who presented with chest pain that had been waxing and waning over the past 24 hours. She had a history of renal failure on dialysis, hypertension, diabetes and a normal catheterisation a year ago. This was her initial ECG.

This ECG shows sinus tachycardia with nonspecific intraventricular delay, tall QRS and widespread PR segment depression. The ST segments are all discordant apart from V4 and V1. These changes were dynamic over serial ECGs. The cath was again normal. Echo showed a trace of pericardial effusion. The diagnosis was myopericarditis.

This ECG is from a man in his 70s who presented with epigastric pain on a background of hypertension.

This ECG shows LBBB and occasional PVCs with discordant changes that do not meet Sgarbossa criteria. The patient self-discharged against advice before an echo could be completed for possible LVH.

This ECG is from a middle-aged male who presented with paroxysmal nocturnal dyspnoea and hypoxia on a background of heart failure, biventricular pacemaker, ICD and previous LV thrombus.

This ECG shows biventricular paced rhythm with RBBB-like morphology and discordant ST elevation in I, aVL, V3-5 due to acutely decompensated heart failure.

This ECG is from a man in his 70s who presented following several episodes of chest pain and dizziness.

This ECG is from a woman in her 80s presented with chest pain. She had a history of 2nd degree AV block with PPM in-situ. This was the initial ECG.

This ECG is from a woman in her 70s who presented after a syncopal episode on a background of coronary artery disease. This was her baseline ECG for comparison.

This ECG shows LBBB with appropriate discordant ST changes.

This ECG is from a man in his 70s who had just undergone an aortic valve replacement.

This ECG shows a ventricular paced rhythm with acceptable discordant ST segments. There was no evidence of ischemia on this ECG.
