1907 Keith & Flack in Jrnl. Anat. & Physiol. XLI. 181 We use the term ‘sino-auricular’ in preference to ‘sino-canalar’ because, although a true sino-canalar junction exists on the dorsal side in the most primitive hearts,..yet in all but these the part of the canal between the sinus and the auricle disappears, and the dorsal junction becomes really a sino-auricular junction.
1942 Bramwell & King Princ. & Pract. Cardiol. v. 87 Closely related to sinus arrhythmia is the disorder known as sino-auricular heart-block.
1976 Archives Internationales de Physiologie et de Biochimie LXXXIV. 81 (heading) Chronotropic responses to experimental ischemia of the canine sino auricular node.
