Wore one for 48 hours and then waited for the results. My general practice doctor called to apologize saying something must have been wrong with the unit and i'd have to repeat the test.
Got hooked up again. Once my GP got the results he called me. Not his office manager or nurse. The doc called. Said he made an appointment with a cardiologist. That day. No time to wait to sort out transport from a family member - take a taxi and go, now. And, by the way, be prepared to have a pacemaker implanted when you go.
I would rather have a perfectly normal Holter monitor test.
