in my first 24hr ECG I had 275 pauses overnight
You may regard your fitness level as akin to that of Superman, and as an ordinary doctor I would probably have little or no problem with someone so apparently fit . . . . . . . . but you must be prepared for a battle with the medics at the Belgrano ! As I said before, I had to do another Holter because of ONE pause of 2.6 seconds. The standards they apply for class 1's are obviously much more stringent !
Good luck anyway ! More and more regular !
