“…Conduction velocity of the contraction is 9-6 cm/sec + 0 3 (n = 10). This value is nearly the same as that determined for spike propagation in the pregnant mouse myometrium (mean value 10-6 cm/sec; Goto, Kuriyama & Abe, 1961). In Fig.…”

“…Being the myometrium a smooth muscle, values of propagation speed in the order of few centimetres per second could be expected (Devedeux et al 1993). While the majority of the reviewed studies, independently on the investigated species, reports figures in this range (Bozler 1938, Daniel & Renner 1960, Goto et al 1961, Wolfs & van Leeuwen 1979, Kanda & Kuriyama 1980, Wikland & Lindblom 1985, Parkington et al 1988, Miller et al 1989, Lammers et al 1999, Lammers et al 2008, de Lau et al 2013a, higher values have also been measured (Lucovnik et al 2011b). Defining a reference physiological range for the propagation speed is therefore difficult.…”

“…On isolated uterine strips of the rat, values of speed in the order of few centimetres were found in the longitudinal layers (Goto et al 1961, Kanda & Kuriyama 1980, Miller et al 1989, Lammers et al 1999. Lower figures were reported in the circumferential direction (Miller et al 1989, Lammers et al 1999 and in the transversal (Lammers et al 1999), although in the transversal segments estimation of velocity may be complicated by the complex shape and broad peaks of the spikes (Miller et al 1989).…”

Propagation of electrical activity in uterine muscle during pregnancy: a review

The uterine muscle (the myometrium) plays its most evident role during pregnancy, when quiescence is required for adequate nourishment and development of the foetus, and during labour, when forceful contractions are needed to expel the foetus and the other products of conception. The myometrium is composed of smooth muscle cells. Contraction is initiated by the spontaneous generation of electrical activity at the cell level in the form of action potentials. The mechanisms underlying uterine quiescence during pregnancy and electrical activation during labour remain largely unknown; as a consequence, the clinical management of preterm contractions during pregnancy and inefficient uterine contractility during labour remains suboptimal. In an effort to improve clinical management of uterine contractions, research has focused on understanding the propagation properties of the electrical activity of the uterus. Different perspectives have been undertaken, from animal and in vitro experiments up to clinical studies and dedicated methods for non‐invasive parameter estimation. A comparison of the results is not straightforward due to the wide range of different approaches reported in the literature. However, previous studies unanimously reveal a unique complexity as compared to other organs in the pattern of uterine electrical activity propagation, which necessarily needs to be taken into consideration for future studies to be conclusive. The aim of this review is to structure current variegated knowledge on the properties of the uterus in terms of pacemaker position, pattern, direction and speed of the electrical activity during pregnancy and labour.
