Аннотация
BACKGROUND: Although both stellate ganglion blockade and nifekalant are effective treatment options for electrical storm, the clinical effect of their combination is uncertain.
CASE SUMMARY: A 71-year-old male patient was admitted to our hospital with acute myocardial infarction and heart failure. Emergency coronary angiography revealed triple-vessel disease. Although coronary artery bypass grafting was planned, the patient experienced electrical storm before the surgery could be performed. Despite complete revascularization by percutaneous coronary intervention, mechanical circulatory support and administration of antiarrhythmic agents (amiodarone and lidocaine), electrical storm was not controlled. After stellate ganglion blockade was initiated on the 9th day of hospitalization, ventricular arrhythmia decreased. However, when stellate ganglion blockade was temporarily discontinued, ventricular arrhythmia increased substantially. Subsequently, combination therapy with stellate ganglion blockade and nifekalant was initiated, after which ventricular arrhythmia disappeared completely. Afterwards, the patient had no further ventricular arrhythmia episodes, and his haemodynamic status gradually improved. The patient was discharged from hospital in an ambulatory condition and did not experience arrhythmia during the follow-up.
DISCUSSION: This case demonstrates that combination therapy with stellate ganglion blockade and nifekalant can completely suppress ventricular arrhythmia, suggesting that blocking multiple conduction pathways is a key to treating refractory electrical storm.
