Nonspecific baseline artefact

The baseline of the ECG should be flat and smooth. Artefact can disrupt this normal baseline, making the ECG more difficult to interpret. Causes of nonspecific baseline artefact include poor electrode contact with the skin.

Computer often fails to diagnose atrial fibrillation in ventricular paced rhythm, and that can be catastrophic

This ECG is from an elderly patient who presented with a massive hemiplegic ischemic stroke due to MCA thrombus.

This ECG shows atrial fibrillation with ventricular pacemaker and significant artefact. The AF went undiagnosed.

What will you do for this altered and bradycardic patient?

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.

Dynamic, Reversible, Ischemic T-wave inversion mimics Wellens’. All trops negative.

This ECG is from a middle aged man who presented with intermittent chest tightness and nausea on walking that resolved with rest. This had happened twice over the past two days. He was likely pain free at the time that this ECG was recorded.

This ECG shows terminal T wave inversion in V2-4, resembling Wellens' waves. There was no wall motion abnormality on echo and troponins were negative (so it was not a true Wellens' syndrome), but a stress echo was markedly positive. Angiogram showed a 95% LAD stenosis and 70% first diagonal stenosis. The cause of the T wave changes was likely ischemia without infarction, ie. unstable angina.

An elderly man with sudden cardiogenic shock, diffuse ST depressions, and STE in aVR

This ECG is from a man in his 80s who presented with sudden onset chest pain and dyspnoea. This was the repeat ECG after he had an aortic valve replacement and CABG.

This ECG is from a man in his 40s who presented with chest discomfort and diaphoresis since waking a few hours earlier, on a background of prior infarction with PCI years ago, active smoking, high cholesterol and hypertension. This was the repeat ECG on day 3, after two reperfusions.

This ECG is from a man in his 40s who presented with chest discomfort and diaphoresis since waking a few hours earlier, on a background of prior infarction with PCI years ago, active smoking, high cholesterol and hypertension. This was the repeat ECG on day 2, after pain returned with nausea and diaphoresis that was exactly like his initial pain.

This ECG is from a man in his 40s who presented with chest discomfort and diaphoresis since waking a few hours earlier, on a background of prior infarction with PCI years ago, active smoking, high cholesterol and hypertension. This was the repeat ECG on day 2, after pain returned with nausea and diaphoresis that was exactly like his initial pain and did not resolve with morphine.
