| nodus rectalis medius | A lymph node along the middle rectal artery that receives afferents from the pararectal nodes and sends efferents to the internal iliac nodes. Synonym: middle rectal node, nodus rectalis medius. (05 Mar 2000) |
| nodus sinuatrialis | sinoatrial node |
| nodus sinuatrialis echo | A postectopic sinus beat occurring earlier than would be expected from the preceding sinus node discharge interval; i.e., the interval following a premature beat of supraventricular origin is less than the ordinary cycle length between sinus beats, whereas ordinarily the interval would be expected to exceed cycle length.
