"First ... understand that fasciculations arise from the discharge of part or the whole of a single motor unit. They are larger and more complex than fibrillation potentials, that is why, that might seems so scary to you. Fasciculations are isolated discharges that recur at irregular intervals. It usually happens in the order of several seconds as you reported. Fasciculations near the surface of a muscle may be visible at the skin, while those deep within the muscle are not. Fasciculations are not caused by poor relaxation as some people think. Fasciculations occur in motor neurone diseases, and some other neurogenic diseases. The most common is radiculopathy and neuropathy, thyroid disease, and peripheral nerve hyperexcitability syndromes. The significance of fasciculations is judged by the company they keep in the muscle. Benign fasciculations that occur with radiculopathy are not accompanied by denervation changes but malign fasciculations usually are."
