Using the extrastimulus method in 100 patients, premature impulses were applied during the relative refractory period of the right atrium. Depending on the atrial response to these impulses we divided our patients in the following 3 groups: Group A: no repetitive firing (61 patients); group B: 1 to 5 additional atrial extrasystoles with a total duration of maximum 1.5 s (27 patients); group C: runs of atrial flutter or fibrilation for at least 8 s (12 patients). The statistical analysis of the following parameters: age, PA interval, absolute and corrected sinus node recovery time did not show any significant difference between the 3 groups. These results suggest that the investigated parameters are of no great importance in the genesis of the atrial vulnerability.
在100例患者中采用额外刺激法，在右心房的相对不应期施加过早冲动。根据心房对这些冲动的反应，我们将患者分为以下3组：A组：无反复激动（61例患者）；B组：1至5次额外房性期前收缩，总持续时间最长1.5秒（27例患者）；C组：房性扑动或颤动发作至少8秒（12例患者）。对以下参数进行统计分析：年龄、PA间期、绝对和校正窦房结恢复时间，3组之间未显示出任何显著差异。这些结果表明，所研究的参数在心房易损性的发生中不太重要。
