During normal sinus rhythm, these signals pass through only one pathway, known as the fast pathway. The fast pathway conducts signals quickly but has a longer rest period before it can send another signal. However, in people with PSVT caused by atrioventricular nodal reentry, both the fast and the slow pathways are activated. [9]
Tachycardia, also called tachyarrhythmia, is a heart rate that exceeds the normal resting rate. [1] In general, a resting heart rate over 100 beats per minute is accepted as tachycardia in adults. [1]
Several groups of drugs slow conduction through the heart, without actually preventing an arrhythmia. These drugs can be used to "rate control" a fast rhythm and make it physically tolerable for the patient. [citation needed] Some arrhythmias promote blood clotting within the heart and increase the risk of embolus and stroke.
Penile-vaginal intercourse or vaginal intercourse is a form of penetrative sexual intercourse in human sexuality, in which an erect penis is inserted into a vagina. [1] Synonyms are: vaginal sex, cohabitation, coitus (Latin: coitus per vaginam), (in elegant colloquial language) intimacy, or (poetic) lovemaking.
From Jackson's last-minute plan to scrap the video and his feud with Vincent Price, to Jones' round-the-clock work ethic, what went into the pop masterpiece
Goose bumps can also be a response to anger or fear: the erect hairs make the animal appear larger, in order to intimidate enemies. This can be observed in the intimidation displays of chimpanzees, [ 11 ] some New World monkeys like the cotton-top tamarin , [ 12 ] in stressed mice [ 13 ] and rats, and in frightened cats.
Fixed word order is one out of many ways to ease the processing of sentence semantics and reducing ambiguity. One method of making the speech stream less open to ambiguity (complete removal of ambiguity is probably impossible) is a fixed order of arguments and other sentence constituents. This works because speech is inherently linear.
Events A, B, and C occur in different order depending on the motion of the observer. The white line represents a plane of simultaneity being moved from the past to the future. In physics , the relativity of simultaneity is the concept that distant simultaneity – whether two spatially separated events occur at the same time – is not absolute ...
