Hi there Rickk90,I also have sinus arrhythmia on some occasions,and your doctor is right,it is a completely normal heart rhythm!! As you breath in your rate speeds up a little and as you breath out your rate slows again!! As for anxiety, that can can cause so many different symptoms, so nothing is impossible! When I get anxious my heart can speed up,I also have more PVC's too!!
