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.
Afib causes irregular heartbeats (ventricular beats that is).
Afib: Atria quiver at fast rate causing fast (not always though) and irregular ventricular heartbeats.
Diagnosing afib is accomplished with an ECG/EKG. (No P wave and fribrillating line instead).
Pulse taking is not a perfect method to determine if you are in afib, but probably if your heartbeat is irregular and you were previously diagnosed, it probably is afib.
I think buying an OMRON ECG is a good investment if you want to be sure.
If I ever got an NSR reading I think I would panic.
