Why the study?
Does premature atrial stimulation reveal differences in sinoatrial conduction time and sinus node response patterns between aged patients with and without sick sinus syndrome?
Population
30 aged patients, including 21 cases without sinus node dysfunction and 9 cases with sick sinus syndrome
Comparison

Abnormal sinus node responses appear common in the elderly; leaves open whether SACT correlation differentiates sick sinus syndrome.
Does premature atrial stimulation reveal differences in sinoatrial conduction time and sinus node response patterns between aged patients with and without sick sinus syndrome?
Aged patients frequently exhibit abnormal sinus nodal responses to premature atrial stimulation, with sinoatrial conduction time correlating with basic sinus cycle length only in those without sick sinus syndrome.
Ueda et al. (1977) studied this question.
