Positive Waves and Fibrillation Potentials

Positive Sharp Wave (PSW) potentials and Fibrillation Potentials (fibs) are seen here associated with EMG needle insertion at an intensity of 1+. Small, sharply spiked fibs are seen with amplitude of 50 uV and later one is seen repeating at 200 uV. In addition, mostly small amplitude PSWs are seen that have characteristic initially downward (positive) sharp slopes and then a more-gradually sloping recovery phase (of repolarization). By convention in electromyography, electrical positive is displayed as down.
