By means of atrial stimulation methods for the establishment of the sinus node recovery time and for the indirect calculation of the so-called sinuatrial conduction time under certain methodical conditions disturbances of the sinus node automatism and of the sinuatrial conduction may be differentiated and moreover latent dysfunctions of the sinus node may be unmasked. Methodical problems in the recognition of the sinus node recovery time by higher-frequent atrial stimulation and the calculation of the sinuatrial conduction time by programmed atrial single or double manifold stimulation result above all on that account, since the various factors which determine the reaction of the sinus node in atrial stimulation are not to be surveyed in the individual case. Since there are no obligatory and reliable criteria for the judgment of the function of the sinus node a statement on sensitivity and specificity of the diagnostic stimulation methods is scarcely possible. With regard to a therapeutic decision aid a higher-frequent stimulation for the determination of the sinus node recovery time is of greater importance than the calculation of the sinuatrial conduction time. For the identification of a disturbed function of the sinus node the two parameters make a diagnostic contribution of approximately the same value.
通过用于确定窦房结恢复时间以及在特定方法条件下间接计算所谓窦房传导时间的心房刺激方法，可以区分窦房结自律性和窦房传导的紊乱，而且还可以揭示窦房结的潜在功能障碍。由于在个别情况下无法全面考虑决定心房刺激时窦房结反应的各种因素，因此通过高频心房刺激识别窦房结恢复时间以及通过程控心房单或双腔刺激计算窦房传导时间存在方法学问题。由于没有判断窦房结功能的强制性和可靠标准，因此几乎不可能对诊断性刺激方法的敏感性和特异性作出说明。对于治疗决策辅助而言，用于确定窦房结恢复时间的高频刺激比计算窦房传导时间更为重要。对于识别窦房结功能紊乱，这两个参数的诊断贡献大致相同。
