Variables determining selection of pacemaker in multivariate logistic regression on 16 289 patients^*

Type of pacemaker	No (%) receiving treatment		Multivariate adjusted odds ratio* (95% CI)
	Men	Women
Single chamber atrial	2226 (2.8)	260 (3.2)	0.89 (0.74 to 1.07)
Single chamber ventricular	5680 (69.6)	6069 (74.6)	0.85 (0.80 to 0.92)
Dual chamber	2252 (27.6)	1802 (22.1)	1.20 (1.12 to 1.30)
Rate responsive†	1852 (22.7)	1482 (18.2)	1.26 (1.17 to 1.37)

^*Adjusted for age, electrocardiographic results, symptoms, and aetiology; the ratios are men/women.
