The effect of the Novocain blockade of the stellate ganglion upon the duration of the electrical systole (Q-T) of the heart was studied in 38 patients. Basic Q-T was normal in 17 patients; in these cases stellate ganglion blockade did not influence the Q-T interval. Of the 21 cases with Q-T prolongation, in 10 the Q-T interval became considerably shorter upon the effect of blockade. In the 11 cases that did not respond to the blockade, ECG repolarization was regular, and there was no arrhythmia. Of the 10 responsive cases with Q-T prolongation, in 9 the repolarization was pathological, and in 6 there was no chronic arrhythmia. The authors discuss the role of the sympathetic nervous system in certain forms of Q-T prolongation.
对38例患者研究了星状神经节奴夫卡因阻滞对心脏电收缩期（Q-T）时长的影响。17例患者的基础Q-T正常；在这些病例中，星状神经节阻滞不影响Q-T间期。在21例Q-T延长的病例中，10例在阻滞作用下Q-T间期显著缩短。在11例对阻滞无反应的病例中，心电图复极正常，且无心律失常。在10例对阻滞有反应的Q-T延长病例中，9例复极异常，6例无慢性心律失常。作者讨论了交感神经系统在某些形式的Q-T延长中的作用。
