Аннотация
BACKGROUND: The R-on-T phenomenon is a malignant arrhythmia associated with potentially catastrophic consequences. It may initiate ventricular tachycardia or ventricular fibrillation, which can result in syncope or sudden cardiac death. This manifestation poses a great challenge for anesthesiologists. However, it is rarely encountered in the perioperative setting.
CASE SUMMARY: We herein present a case in which the R-on-T phenomenon was incidentally revealed by 24-h Holter monitoring in a patient diagnosed with sigmoid colon cancer. Careful evaluation and treatment with mexiletine were carried out preoperatively under consultation with a cardiovascular specialist, and surgery was uneventfully performed under general anesthesia after thorough preparation.
CONCLUSION: Physicians should be vigilant about this infrequent but potentially fatal arrhythmia. Our experience suggests that the anesthetic process can be greatly optimized with careful preparation.
