DETERMINATION AUXILIARY METHOD FOR PRESENCE OR ABSENCE OF EXCITATION-CONTRACTION COUPLING FAILURE

摘要

PROBLEM TO BE SOLVED: To provide a determination auxiliary method for the presence or absence of an excitation-contraction coupling failure, the method that is simple and precise.SOLUTION: Evoked electromyogram obtained by single nerve stimulation and evoked mechanomyogram are recorded, and a difference of those distal latency is measured. When the difference of the distal latency increases in comparison with control, a determination is made that an excitation-contraction coupling failure is present. The evoked mechanomyogram obtained by repetitive nerve stimulation is recorded and its amplitude is measured. When the amplitude of the evoked mechanomyogram decreases gradually in comparison with the control even though the amplitude of the evoked electromyogram is constant, the determination is made that the excitation-contraction coupling failure is present.
