I have found online a book called
“The cardiac care unit survival guide”
While it is written for health care professionals it does include sections written for patients.
From what I can read online it’s extremely informative and hopefully a copy will be with me soon.
Downside is the price however limited run technical books can be expensive to produce.
ISBN -13: 978-1-4511-1047-0
Author Eyal Herzog
I thought may be of interest to anybody wishing to research a heart condition.
