Afib affects Glucose levels?

I've noticed when I'm in Afib my sugar levels go up and I can't seem to get them down.... From 80 - 150 then they go as high as 250 in Afib and can't get it to stay below 180..... As soon as I go out of Afib my glucose numbers drop another 80 points..... I wear a continuos glucose monitor so I know every 5 minutes even while sleeping what my glucose reading are. I use Kardia by AliveCor to determine my cardiac condition. Anyone else go this cycle or have this reaction?

That's an interesting observation Larry. Although I'm not diabetic ( or pre ) I do measure my blood sugar levels at home from time to time ( hypochondriac ? Moi ?! ) I shall take a measurement next time I go Into AF out of interest.

I am diabetic and keep a close eye on my bg levels. I haven't tried taking it while in afib, but will do so next time. Very interesting point. What I have noticed is that when I get an infection, as I had a month ago, ( and it's kind of rumbled on ever since,) my bg goes high all the time. It's throwing my 'good' records all over the place!

Interesting.... I never thought of that connection..... All I know is for some unknown reason I had BG under great control and for no apparent reason away higher and unable to control like I was the last few months...... The Afib is for sure not helping.

Hi Larry, Glucose levels are affected by stress. When you are in AF your body is under stress, so I am not surprised that you are finding this. As an aside, I have a friend who is diabetic, and has AF, and has recently normalized her blood glucose by switching to a whole food plant based diet. Her physician is astounded and joyful that she was able to reverse her diabetes by taking animal products from her diet. Good luck to you.

Yes I also see great results with better nutrition. 8 months ago my a1c was 10.5 and now 7.4 and getting better every month....I eat 90% less meat.....amongst other lifestyle changes....

The one time I went to the emergency room before I had been properly diagnosed with afib (It took a few months of visiting a couple of different doctors before ECG was finally performed) my glucose level was tested and found to be fairly high (175). I started testing it regularly because the ER Doctor said high heart rate, syncope and general fatigue might be due to blood sugar imbalances and after a lot of finger pricking over the next few months eventually discovered that it shot up whenever I was experiencing tachycardia. My normal range is 80 to 125 even after meals. I think there is a link and that it must have something to do with the body frantically trying to provide energy to the heart during these episodes.

Since I wear a continuous glucose monitor it shows a definite link between sugar level and heart condition, which I can also graph with Kardia. Just yesterday I woke after 3 perfect days of BG control and NSR to an irregular pulse and Afib. My BG hovered all day around 190 even with 2 hours of walking..... Never dropped! Then at around midnight still at about 197 BG I thought let me walk some more. At that time my BG dropped about 10 points foe every 5 minutes down to 97! I checked my pulse in the middle of this excercise to see a rock steady pulse about 95 bpm. No Afib. Curiously when I asked my EP cardiologist he stated an opposite correlation. He said Afib would lower BG levels. I fully respect his training and credentials but clearly know what I see on my personal monitors. Woke this morning..... NSR BG at 100. As a mechanical engineer I would think a good pump circulating blood efficiently to all organs and muscles would put everything in good working order........
