A 72-year-old man with Wolff-Parkinson-White syndrome and sick sinus syndrome had colon cancer, suggesting that the conduction of the Kent bundle depends on the serum potassium level. Because of severe diarrhea or furosemide administration, the serum potassium level in this patient was sometimes low. When it was less than 3.0 mEq/l delta wave or re-entrant tachycardia via the Kent bundle occurred. These were suppressed by the administration of potassium. On the other hand, when the serum potassium level was normal or high, neither effect was noted, and electrophysiological studies, done when the level was 3.2 mEq/l, showed no evidence of conduction by the accessory pathway. This suggests that conduction through the Kent bundle depends on the serum potassium level.
一名患有预激综合征和病态窦房结综合征的72岁男性患有结肠癌，这表明肯特束的传导取决于血清钾水平。由于严重腹泻或使用速尿，该患者的血清钾水平有时会降低。当血清钾水平低于3.0 mEq/l时，会出现δ波或通过肯特束的折返性心动过速。补充钾后这些症状得到缓解。另一方面，当血清钾水平正常或升高时，则未观察到任何影响，并且在血清钾水平为3.2 mEq/l时进行的电生理研究未显示有旁道传导的证据。这表明通过肯特束的传导取决于血清钾水平。
