We couldn’t be more excited about where Roshcast has been or where it is going. In honor of hitting one year, we are doing another trauma ring tone competition. During episodes 34 to 38, listen for a trauma ring tone, and tweet the exact time to us or e-mail the time to us. A few weeks ago, we also launched a new partnership with the EM Clerkship podcast as a core EM corollary for selected topics. This week, we are doing another crossover episode, in which we return to cardiac arrhythmias — specifically, bradycardia. Let’s get the episode started with a rapid review of some essential vitamins, which were recently covered on the Rosh Blog.
Now onto this week’s podcast

There are no other ST-segment abnormalities. Which of the following is the most appropriate next step in management?
A. Administer aspirin, heparin and admit for acute coronary syndrome
