Despite guidelines on pacemaker implantation, German researchers have reported that women appear to receive less sophisticated devices than men, regardless of their medical condition.

The researchers, from the University of Ulm Medical Centre in Ulm, Germany, and Justus Liebig University in Giessen, Germany, studied information from more than 31000 patients listed in a pacemaker registry in 1992 and1993. After adjusting for age, clinical symptoms, underlying disease, and electrocardiographic findings, their analysis showed that higher proportions of women received single-chamber systems, while more men received dual-chamber or rate-responsive systems.

Their analysis also showed that more men than women experienced atrioventricular block, a condition for which dual-chamber pacemakers generally are preferred. However, the researchers said more women than men presented with sinus node dysfunction, a condition for which several studies have found that dual-chamber pacemakers produce better outcomes than single-chamber devices.

Prospective studies are needed to assess the roles of . . . [Full Text of this Article]
