The authors present a group of 67 patients, mean age 63 +/- 15 years, where they applied on account of suspected dysfunction of the sinoatrial node (SA) the atropine test (AT), 24-hour Holter monitoring and transoesophageal stimulation of the atria (TESP). The objective of the investigation was to test the reliability and yield of the mentioned methods and to investigate more closely the relations of their final indicators. Correlation analysis revealed a positive relationship between the maximal frequency during AT and the mean daily (r = 0.553, p < 0.001) and minimal frequency during Holter monitoring (r = 0.349, p < 0.0025). The recovery periods of the SA node were negatively related to the mean, minimal and maximal frequency during Holter monitoring. The relative rise of SF during the atropine test did not correlate with any Holter parameter nor with the recovery periods of the SA node. The length of the pause (Holter) did not correlate with any of the evaluated parameters. Based on the mentioned findings, the authors conclude that the diagnostic value of the mentioned non-invasive tests, when used separately, is limited but increases when the tests are combined.
作者报告了一组67例患者，平均年龄63±15岁，这些患者因怀疑窦房结（SA）功能障碍接受了阿托品试验（AT）、24小时动态心电图监测和经食管心房刺激（TESP）。研究目的是检验上述方法的可靠性和有效性，并更深入地研究其最终指标之间的关系。相关性分析显示，AT期间的最大频率与动态心电图监测的日均频率（r = 0.553，p < 0.001）和最低频率（r = 0.349，p < 0.0025）之间呈正相关。窦房结的恢复时间与动态心电图监测期间的平均、最低和最大频率呈负相关。阿托品试验期间窦房结恢复时间的相对增加与任何动态心电图参数或窦房结的恢复时间均无相关性。（动态心电图监测的）停搏时间与任何评估参数均无相关性。基于上述发现，作者得出结论，上述非侵入性检查单独使用时诊断价值有限，但联合使用时诊断价值会增加。
