E97 - Bayes and Calcium Before Diltiazem in Atrial Fibrillation
Download MP3Train the Best. Change EMS.
Howdy, y'all, I'm Dr Jeff Jarvis, and I'm the host of the EMS lighthouse project podcast, but I'm also the medical director for the new EMS system we're building in Fort Worth Texas. We are looking for an experienced critical care paramedic who is an effective and inspiring educator to lead the initial and continuing training and credentialing of a new team of Critical Care Paramedics who will be responding to our highest acuity calls. The salary is negotiable but starts between $65,000 and $80,000 a year for this office position. Whether y'all wear cowboy boots or Birkenstocks, Fort Worth can be a great place to live and work. So if you're ready to create a world-class EMS system and change the EMS world with us, give us a call at 817-953-3083, take care y'all.

We covered a paper in episode 81 that suggested treating atrial fibrillation with rapid ventricular response in the field could lower mortality. But it also drops BP a bit. Could pretreating these patients with calcium lower the risk of hypotension? Dr Jarvis puts on his nerd hat and uses Bayesian analysis to assess a new randomized, placebo-controlled study that looked at just this thing. Why is he going off on this Bayes thing? Because he’s been reading a couple of book on it and wanted to take it for a spin.
