| reciprocal beat | See: reciprocal rhythm. (05 Mar 2000) |
| reciprocal bigeminy | Paired beats, each pair consisting of an A-V nodal beat followed by a reciprocal beat. (05 Mar 2000) |
| reciprocal forces | In dentistry, force's whereby the resistance of one or more teeth is utilised to move one or more opposing teeth. (05 Mar 2000) |
| reciprocal inhibition | Contraction in a muscle is accompanied by a loss of tone or by relaxation in the antagonistic muscle. Synonym: reciprocal inhibition. (05 Mar 2000) |
| reciprocal innervation | Contraction in a muscle is accompanied by a loss of tone or by relaxation in the antagonistic muscle. Synonym: reciprocal inhibition. (05 Mar 2000) |
| reciprocal rhythm | A cardiac arrhythmia in which the impulse arising in the A-V junction descends to and activates the ventricles on one intrajunctional pathway and simultaneously ascends toward the atria in parallel pathways; before reaching the atria, however, the impulse is reflected downward and again activates the ventricles, producing an echo or reciprocal beat; recognised in the electrocardiogram by the presence of an inverted P wave in lead aVF and usually II sandwiched between two ventricular complexes aberrantly, both of which may be normal or one of which may be conducted.

| reciprocal transfusion | An attempt to confer immunity by transfusing blood taken from a donor into a receiver suffering from the same affection, the balance being maintained by transfusing an equal amount from the receiver to the donor. (05 Mar 2000) |
| reciprocal translocation | Translocation without demonstrable loss of genetic material. (05 Mar 2000) |
| reciprocal treanslocation | Mutual exchange of chromosome segments between two nonhomologous chromosomes (chromosomes that do not belong to the same pair). (12 Dec 1998) |
| reversed reciprocal rhythm | A cardiac arrhythmia in which a normal sinus impulse, before reaching the ventricles, is reflected backward to the atria; thus in the electrocardiogram a ventricular complex is sandwiched between a normal sinus P wave and a retrograde P wave; if the dysrhythmia continues, subsequent cycles are similar to those of reciprocating rhythm.

| law of reciprocal proportions | The relative weights in which two substances form a chemical union singly with a third are the same as, or simple multiples of, those in which they unite with each other; a corollary of the law of definite proportions. Synonym: law of multiple proportions. (05 Mar 2000) |
