A member asked:

Is a fib caused by heart structural probs or electrical probs? can normal echo/blood/thyroid rule it out? is it usually pathology rated or spontaneous

A doctor has provided 1 answer

Afib: good question..there appear to be both structural and bioelectrical possible causes for afib. Some of the causes can have the 'normal' tests you list
