The number of body sites with abnormal warm or cold thresholds found in each patient correlates with the QTc supine values. QTc supine values v number of sites with abnormal cold perception: Rs = 0.57; p<0.01. QTc supine valuesv number of sites with abnormal warm perception: Rs = 0.59; p<0.001. QTc supine valuesv number of sites with abnormal warm or cold perception: Rs = 0.46; p<0.05. Numbers in parentheses refer to the three patients who had cardiac arrest within 12 months after study.
