The Electrophysiological Features in a Patient with Acute Organophosphate Intoxication

ABSTRACT

Acute organophosphate intoxication has characteristic electrophysiological features, which include repetitive potentials in nerve conduction studies and decrement (or decrement-increment) responses in repetitive nerve stimulation tests. We experienced a patient who presented with abdominal discomfort, followed by cardiac arrest and then showed motor weakness. The electrophysiological studies revealed decrement responses which were characteristic features of acute organophosphate intoxication. We report clinical and electrophysiological features of acute organophosphate intoxication followed with a literature review.
