Wired up in hospital and when allowed out of bed yes there is a belt box which is connected to the hospital WiFi.
No use at all at home.
ECG always shows damage, so the only use would be to record time of death.
Hospital is different, you are not allowed out of the unit on your own if it shows Cardiac Arrest, they have the equipment and drugs and skilled staff to deal with it.
I know when I am having a Cardiac Event, no need for alarms, I sweat, vomit, curl up and the pain goes down my left arm.
I gasp for breath.
I have been given some medication to use in such an emergency, it has worked so far.
It is all about quality of life and that is my choice.
I am not spending the rest of my days in a hospital bed on permanent bed rest and having my bum wiped because I have lines in.
I am much happier at home, pottering in the garden, looking after my tropical fish and watching what I want on my android TV and being on here.
A little off the general drift of the conversation but still within the terms of the thread title - I received these links today and very funny they are too IMHO:
