| werner-his disease | Named for the German physician heinrich werner (not the werner of werner's syndrome) and the swiss physician wilhelm his, jr. (who described the bundle of his in the heart). See fever, wolhynia. (12 Dec 1998) |
| his | 1. Belonging or pertaining to him; used as a pronominal adjective or adjective pronoun; as, tell John his papers are ready; formerly used also for its, but this use is now obsolete. "No comfortable star did lend his light." (Shak) "Who can impress the forest, bid the tree Unfix his earth-bound root?" (Shak) Also formerly used in connection with a noun simply as a sign of the possessive. "The king his son." Shak. "By young Telemachus his blooming years." Pope. This his is probably a corruption of the old possessive ending -is or -es, which, being written as a separate word, was at length confounded with the pronoun his. 2. The possessive of he; as, the book is his. "The sea is his, and he made it." Origin: AS. His of him, his, gen. Masc. & neut. Of h, neut. Hit. See He. Source: Websters Dictionary (01 Mar 1998) |
| His' band | The bundle of modified cardiac muscle fibres that begins at the atrioventricular node as the trunk of the atrioventricular bundle and passes through the right atrioventricular fibrous ring to the membranous part of the interventricular septum where the trunk divides into two branches, the right crus of the atrioventricular bundle and the left crus of the atrioventricular bundle; the two crura ramify in the subendocardium of their respective ventricles. Synonym: fasciculus atrioventricularis, atrioventricular band, Gaskell's bridge, His' band, His' bundle, bundle of His, Keith's bundle, Kent's bundle, Kent-His bundle, ventriculonector.

| His bundle electrogram | An electrogram recorded from the His bundle, either in the experimental animal or in man during cardiac catheterization. (05 Mar 2000) |
| his bundle electrography | <investigation> This test studies the electrical activity of the bundle of HIS. The bundle of HIS is a group of electrical fibres in the heart that are responsible for transmitting the electrical impulses which generate a normal cardiac contraction. This test may be performed in cases of cardiac arrhythmias, to locate a specific area responsible for a conduction defect and to determine the need for cardiac pacemaker placement. The test involves the passage of a an electrode tipped catheter into the heart. This catheter is usually threaded through a neck, arm or chest vein. Measurements of the HIS bundle can then be performed while standard ECG leads are placed on the arms and legs. This test carries a small risk of bleeding, arrhythmias, embolism, heart attack and stroke. It is performed by a specially trained cardiologist. (27 Sep 1997) |
