Gingernut is quite right about the resting ecg. As a predictive tool, it is as much use as t*ts on a bull. It can only tell you what has happened, never what is going to happen. As a case in point, I renewed my Class 1 which included a resting ecg, which showed a normal sinus rhythm. BP was described as upper normal, but passable. Within 2 weeks I had a serious heart attack and lost my licence. It's all about lifestyle, family history etc etc.. Personally, I would be inclined to do what you can lifestyle wise ( Diet, smoking, alcohol etc) and leave the rest to chance.
