This week, in addition to my own blog, I'm going to feature a guest case study by Guru member Vince DiGiulio, EMT-CC. This past Monday, Vince messaged me (along with Dr. Ken Grauer) on Facebook and requested my input and opinion on these serial ECGs. With Vince's blessing, he gave me permission to use any of his original 12-lead ECGs here on the Guru. Of his 6 ECGs, I've decided to post 4 of them here.
