Bizarre T-wave inversions, with Negative U-waves and Very long QT. And a myocardial viability study.

This ECG is from a man in his 60s who developed hypokalemia during a complicated hospital admission including GI bleed and anaemia.

This ECG shows inverted T waves and inverted U waves with a very prolonged QT. There is subtle ST elevation in inferior and lateral leads. Troponin was elevated, echo showed regional wall motion abnormalities apical and anteriorly. Angiogram showed severe multivessel disease and an apical LAD occlusion of uncertain age. The most likely cause was either a small infarction or takotsubo.

ECG Blog #167 (Reciprocal-OMI-Normal)

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.

Acute MI, pain onset 24-48 hours ago. Should the patient go for emergent angiogram/PCI?

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).

Two patients with RBBB

This ECG is from a man in his 50s who presented with intermittent chest pain and shortness of breath for the past 3 days with vomiting.

This ECG shows RBBB with inferior and lateral ST elevation due to an acute MI (occluded OM2).

Inferior Subtle ST elevation: straight ST segment, but also no reciprocal ST depression in aVL: which is more important?

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.

2 ECGs texted to me. Minimal STE in inferior leads. How important is it?

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.

ST segment concavity is just one small piece of the puzzle that is pattern recognition

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.

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.

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.

Three EKGs shown to me – which if any need emergent reperfusion? ECG 3

This ECG is from a man in his 50s who presented with chest pain on a background of known coronary artery disease.

This ECG shows ST elevation with Q waves, high voltage QRS and atypical ST morphology for acute ischemia. On angiography he had three vessel disease but no obvious acute culprit. Serial troponins did not rise and serial ECGs showed no evolution.

IVCD, Saddleback STE in III, with reciprocal STD in aVL: Is it pseudoOMI or OMI? Echo with Speckle Tracking gives the answer.

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.

A Patient with Respiratory Failure and a Computer “Normal” ECG

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.
