| 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) |

| reciprocally | 1. In a reciprocal manner; so that each affects the other, and is equally affected by it; interchangeably; mutually. "These two particles to reciprocally affect each other with the same force." (Bentley) 2. <mathematics> In the manner of reciprocals. <mathematics> Reciprocally proportional, proportional, as two variable quantities, so that the one shall have a constant ratio to the reciprocal of the other.

| reciprocate | To move forward and backward alternately; to recur in vicissitude; to act interchangeably; to alternate. "One brawny smith the puffing bellows plies, And draws and blows reciprocating air." (Dryden) Reciprocating engine, a steam, air, or gas engine, etc, in which the piston moves back and forth; in distinction from a rotary engine, in which the piston travels continuously in one direction in a circular path. <mechanics> Reciprocating motion, motion alternately backward and forward, or up and down, as of a piston rod. Origin: L. Reciprocatus, p. P. Of reciprocare. See Reciprocal. Source: Websters Dictionary (01 Mar 1998) |
| reciprocating rhythm | A cardiac arrhythmia initiated by an A-V junctional beat followed in turn by a reciprocal beat; the descending impulse of the reciprocal beat, before reaching the ventricles, is also reflected backward to the atria, but before reaching the atria is reflected downward again to the ventricles, so that there is both retrograde atrial activation and orthograde ventricular activation.

| reciprocation | In prosthodontics, the means by which one part of an appliance is made to counter the effect created by another part. Origin: L. Reciprocare, pp. Reciprocatus, to move back and forth (05 Mar 2000) |
| reciprocity law | In two photochemical reactions, e.g., the darkening of a photographic plate or film, if the product of the intensity of illumination and the time of exposure are equal, the quantities of chemical material undergoing change will be equal; the retina for short periods of exposure obeys this law. Synonym: reciprocity law, Roscoe-Bunsen law. (05 Mar 2000) |
| reciprocornous | <zoology> Having horns turning backward and then forward, like those of a ram. Origin: L. Reciprocus returning, reciprocal + cornu horn. Source: Websters Dictionary (01 Mar 1998) |

| Recklinghausen's disease of bone | Rarefying osteitis with fibrous degeneration and formation of cysts, and with the presence of fibrous nodules on the affected bones. It is due to marked osteoclastic activity secondary to hyperfunction of the parathyroid glands. (12 Dec 1998) |
