I have long been of the mind that sugar is one of the main triggers of ectopics (which in turn could start an arrhythmia) so decided to do a little trial which may be of interest.
Over the last 3 months (was going to wait 6 months but outcome was so consistent that now ended the trial), when I eat too much sugar - more than one cake within an hour, around 10 minutes later my heart starts having ectopics, these are consistent ectopics in that every fifth beat is a double beat. Now these are not bad ectopics and in truth would probably not know that were there if I was not sensitised to them, these these last around 20 minutes. The other interesting thing is that these ectopics only appear when my heart is resting with a HR of 55 to 59, they do not happen when my HR is 60 or above?
In my case I have been in NSR since my ablation two and a half years ago stand fast the first 3 months recovery and the odd short runs of tachycardia when I over exert myself. The ablation itself was, in the main, a success (I still have MAT which could not be ablated) as I now live a normal life with very little heart problems - I do get the odd ectopic (everyone does) but these are now hardly noticeable.
Whilst we are all different and will have different triggers I thought this may be of interest as I am sure there will be many having similar issues when taking too much sugar.
