Normalisation of slow-relaxing tendon reflexes (Woltman's sign) after cardiac pacing for complete heart block.

A patient whose slow-relaxing tendon reflexes returned to normal after cardiac pacing for complete heart block is reported. Since the patient was euthyroid, these observations add further weight to previous suggestions that intrinsic catecholaminergic mechanisms, as well as thyroid status, may play a role in the pathogenesis of slow-relaxing reflexes.
