Elongated labia Elongated labia Elongated labia (also known as Sinus pudoris or macronympha and albeit nonmedically, as khoikhoi apron or hottentot apron), are a feature of certain Khoikhoi people, whose female members develop relatively elongated labia minora, hanging up to four inches outside their vulva when they are standing in an upright position. The "apron" designation was apparently gained from the tendency of early European descriptions to misidentify the pair of labia as a single, wide organ, which they called, in French, a "tablier", or "apron". This trait was first noted as far back as the 17th century, but became extensively documented
Sinus rhythm to them; in these cases, the speed of the "sinus rhythm of the atria" and the speed of the ventricular rhythm must be calculated separately. By convention, the term "normal sinus rhythm" is taken to imply that not only are the P waves (reflecting activity of the sinus node itself) normal in morphology, but that all other ECG measurements are also normal. Criteria therefore include: Sinus rhythm A sinus rhythm is any cardiac rhythm in which depolarization of the cardiac muscle begins at the sinus node. It is characterised by the presence of correctly oriented P waves on the electrocardiogram
