Wow, I am so sorry, that is absolutely horrific. What was causing his heart to race? An infection? What a nightmare, my condolences. I’m in New York unfortunately. I would ask people in your church/temple for help if you go to either. Do you have any friends/neighbors who can help?
I don’t know what caused his heart to race, Up until about a year ago, he hadn’t seen a doctor in over 20 years. They said he was pre-diabetic, but other than that, he had no issues.
