EMG - Difference between fasciculation and fibrillation?
I know the definitions of these two in a physical sense - but I've been reading about EMG results that show fasciculations and EMG results that show fibrillations.

How do they show up differently on the EMG?

When I had my EMG, even when my muscles were at rest some of them had spikes in the line across the monitor. In some muscles, these spikes looked like little cones, and in other muscles, the spikes were taller and skinner.

The sound I heard when I saw the spikes was either a "pop-pop-pop-pop" or a "whoosh-whoosh-whoosh-whoosh."

Does this sound like fasciculations or fibrillations? All the neurologist said was that the results were abnormal but were not clear cut enough for her to give me a diagnosis that day.

Thanks for any help you can give.

Sorry, I should have said "in a dictionary sense." I didn't mean to imply that fibrillations were apparent to patients.
