Teachable Moment: Spike Form Fibrillation Potentials and Positive Sharp Waves-Video

Video Transcription

Video Summary

In this video, the speaker discusses the significance of spike form fibrillation potentials and positive sharp wave fibrillation potentials in muscle fibers. They explain that these two morphologies of fibrillation potentials can both be distinguished as fibrillation potentials occurring in denervated muscle fibers based on their firing patterns. The speaker mentions a debate in the literature regarding the differences in significance between these two morphologies. They explain that the morphology of the fibrillation potential does not necessarily reflect the disease state, but rather the location of the recording electrode in relation to where the potential is being generated. They emphasize that both morphologies can occur in the same muscle fiber and cannot be used to make a clinical or electrodiagnostic diagnosis. No credits are mentioned.
