Extreme shock and cardiac arrest in COVID patient
This is a 30-something healthy patient presented with COVID pneumonia who presented to the ED. He was moderately hypoxic. He had the following EKG recorded:Low voltage, suggests effusion.(see Ken ' s discussion of low voltage below)There is a QS-wave in V2.There is minimal, probably normal STE in V2-V6.A bedside cardiac ultrasound was normal, with no effusion. He had troponins ordered, and the first returned at 72 ng/L (Abbott Architect hs cTnI; URL for males = 34 ng/L). An elevated troponin in a COVID patient confers about 4x the risk of mortality than a normal one.He was admitted on oxygen and was&...

A woman in her 60s with 6 hours of chest pain, dyspnea, tachycardia, and hypoxemia
Discussion:The management in this case is unfortunately common practice at many places around the world where we receive cases. Why would an interventionalist violate multiple recommendations from their own guidelines and watch at 10am while an LAD occlusion plays out in front of them? What could explain why some providers do not seem interested in the fact that LAD occlusion can be identified by something other than STEMI criteria? Or why the wall motion abnormality matching the distribution of concern is ignored? The only plausible explanation is that they have been taught that this is standard practice. Under the STEMI ...

Optical coherence tomography (OCT) – Cardiology MCQ – Answer
Optical coherence tomography (OCT) – Cardiology MCQ – Answer
Optical coherence tomography (OCT) compared to intravascular ultrasound (IVUS) has – Correct answer: 1. OCT has higher resolution but lower depth penetration
Optical coherence tomography (OCT) has much higher resolution compared to intravascular ultrasound. It has the resolution of the range of 10 – 20 microns, which is an order of magnitude better than that of intravascular ultrasound. But the limitation is the lower depth of tissue penetration which is only 2 to 3 millimeters, compared to the 10 millimeter tissue penetration of current i...

A young woman in her early 20s with syncope
Written by Pendell MeyersA 20 year old female with an episode of syncope was triage to my low acuity zone one morning. Her vitals were within normal limits except for her heart rate of 109 bpm.I immediately went to evaluate her, without looking in the chart first. I found a well appearing young lady in the room with her parents who witnessed the event. She stated that she was sitting on a shallow ledge in a pool when she became lightheaded, so she got up out of the pool and then briefly syncopized next to the pool in front of her parents, who were able to catch her preventing any trauma. She returned to normal within 30 se...

Repost: 63 minutes of ventricular fibrillation, followed by shock. What is going on?
In this study, 5% of VF arrest was due to PE: V fib is initial rhythm in PE in 3 of 60 cases. On the other hand, if the presenting rhythm is PEA, then pulmonary embolism is likely. When there is VF in PE, it is not the initial rhythm, but occurs after prolonged PEA renders the myocardium ischemic.--Another study by Courtney and Kline found that, of cases of arrest that had autopsy and found that a presenting rhythm of VF/VT had an odds ratio of 0.02 for massive pulmonary embolism as the etiology, vs 41.9 for PEA. ===================================MY Comment by KEN ...

A man in his 50s with fever and shortness of breath
Written by Pendell MeyersA man in his 50s with HTN, HLD, obesity, and restrictive lung disease presented with shortness of breath worsening over the past 3 days. He also had a cough and subjective fevers. He denied chest pain. His vitals were within normal limits.Here is his triage ECG (no baseline available):What do you think?Findings: - sinus rhythm at about 100 bpm - STE in I and aVL (meets STEMI criteria) - hint of STD in III and aVF - STD in V1 and V2 - hyperacute T-waves in I and aVL (with reciprocal negative hyperacute T in III)Interpretation:This is definitive evidence of acute transmural i...

A patient with abdominal pain associated with alcohol withdrawal and alcoholic ketoacidosis
While at work, one my partners showed me this ECG of a 50-something woman with abdominal pain associated with alcohol withdrawal and alcoholic ketoacidosis. There was no reported chest pain or SOB.What do you think?I said it " looks like takotsubo. Electrolytes might contribute. Are they back yet? (they were not). I do not think this is a coronary event. "He asked why.I responded: " bizarre T-waves, with T-wave inversion and extremely long QT. The computer measures the QT at 506 ms, but it really is more like 560-580 ms, with a QTc of 600-620 ms. This is not at all typical of ACS but ver...
