INPACT ON CLINICAL PRACTICE In long standing pains,treatment results achieved by breaking nthe re-entry current can be expected to last only a until the loop is functioning again. In that case adding additional approaches seems better than stopping the first method and shifting to an other. More attention should be given to the use of drugs the are known to be influencing the cardiac re-entry mechanism.Treatment of peripheral loop sites can be applied before approach of central nervous system mechanismsIn cases Where a pain loop can be expected,treatment of sympathetic nbervous system involvement should be routine. With the objective of discontinuing of a painmaintaining nervous loop, the slow conducting antidromic path should be blocked. Methods like physiotherapy, acupuncture,injection of physiological saline or low concentrated local anaesthetics seen to be first choice.
CONCLUSION It is postulated that in the course of paintransmission circular roundabout currents can be present. Both excitation and inhibition of passing afferent depolarisation could take place at a loop site.
