Differential diagnosis of wide complex tachycardias – Part V

Entry Img

Let’s switch gears a little bit and discuss irregular or polymorphic wide complex tachycardias. First I need to tell you a story. A few years ago I was teaching ACLS to a group of mostly nurses at the local community hospital. I volunteered to teach Bradycardias, Tachycardias, and the Hypotension/Shock/Acute Pulmonary Edema algorithm. At first […]

Rate Related VS. Primary ST-T Changes:
I think I will have to agree with Michael; I just don't see all that much evidence of WPW; typically with WPW & AF the complexes vary in width and morphology due to the combination of the accessory pathway and normal pathways which I just don't see here. The rate doesn't seem to match what…

59 year old male: chest pressure – Conclusion
I read back over the details on this case and they didn't include whether or not the patient was Left-dominant. Your hunch is probably correct!

Magnesium and Cardiac Action Potential
I have a background in biochemistry, and so am able to navigate the medical science more than someone without this background. My mom has atrial fibrillation, and so I decided to do some investigation. I am AMAZED to find out how little her primary care doctor knows about Magnesium/Potassium/Calcium concentrations as they pertain to Atrial…

Rate Related VS. Primary ST-T Changes:
He's complaining of 10/10 chest pain that coincided with palpitations with a HR of 206 that is probably A-Fib. I am guessing that if you correct his rate you will allow his myocardium to become perfused again and his chest pain will subside. I would pre-sedate him with Midazolam 2mg and electrically cardiovert starting @…

Rate Related VS. Primary ST-T Changes:
I just don't see adequate evidence for WPW. I would be confident administering this PT Cardizem at .25mg/kg based on his hemodynamic stability. I'd also like to know more about PT history, like does he have AFIB at baseline and, if so, what does he take for it. I would also ask about a history…
