REPETITIVE RESPONSE TO SINGLE STIMULATION


from M. Al-Lozi
Two CMAPs after single stimulus
  • Second CMAP (Arrow)
    • Smaller than the first
    • Follows first CMAP with consistent latency: Independent of site of nerve stimulation
  • Due to prolonged action of acetylcholine at neuromuscular junctions
  • Occurs with



from M. Al-Lozi
