Amazing. UHC shareholders are suing because after the CEO shooting, the company was “no longer willing” to use “aggressive, anti-consumer tactics” to generate the profits they were promised. A gift from the content gods.

Interesting ECG from the Muse reading queue that I'm unsure about. Heart transplant in 1998. Couldn't find op note, but suspect bicaval technique given date of operation. ECGs dating to 1998, none in this rhythm. 2:1 AV relationship, but the conducted PR changes after R4. What explains this?
