Ej. Langford et al., ATRIAL PERMANENT PACING FOR SINUS NODE DYSFUNCTION WITH ABSENT RIGHT SUPERIOR VENA-CAVA, International journal of cardiology, 40(2), 1993, pp. 177-178
In patients with sinus node dysfunction and normal atrioventricular co
nduction, single chamber atrial pacing (AAI or AAIR mode) represents t
he most physiological treatment. Sinus node dysfunction is recognised
in association with an absent right superior vena cava, and we present
a case in which complete resolution of symptoms was achieved with end
ocardial atrial permanent pacing.
