Atrial Fibrillation (AFib) Support Group
Atrial fibrillation (AF or afib) is an abnormal heart rhythm (cardiac arrhythmia) which involves the two small, upper heart chambers (the atria). Heart beats in a normal heart begin after electricity generated in the atria by the sinoatrial node spread through the heart and cause contraction of the heart muscle and pumping of blood.
I tend to have that problem in both arms, in the evening.... it's called 'truck driver's elbow'.... where you tend to depress the nerves that run through the elbow, and thus cause them to feel numb. In my case, it's usually the outside 2 fingers...
There's something about the way I lay or fold my arms when i sleep.
