Follow-up Of Tachyarrhythmia Ablation In Aviators

Introduction Most of the tachyarrhythmia flight personnel,due to their hemodynamic effects,are flying unqualified according to the flight identification criteria(including flying with drugs).With the development of medical science,most tachyarrhythmias can be cured by radiofrequency ablation.The foreign military has already privileged the release of most people with rapid arrhythmia.Our hospital draws on the experience of foreign troops and strictly controls the standards of release.From 2004 to now,there is a high rate of missed after radiofrequency ablation.The purpose of this Question is to conduct follow-up studies on cases that have already been released,providing a reliable basis for the formation of flight standards and optimal release times to ensure flight safety and combat effectiveness maintenance.Method Flight personnel who underwent tachyarrhythmia radiofrequency ablation in our hospital from January 1,2004 to December 31,2017 were included in the study.Follow-up was collected before December 31,2018.Follow-up indicators included tachyarrhythmia episodes,palpitations caused by tachyarrhythmia,hemodynamic symptoms(obscured vision,unconsciousness,progressive aggravation of chest pain,syncope or syncope),flight hours after flight,flight status and aeromedical identification.Statistical methods were performed using EXCEL software.The measurement data were expressed as mean ± standard deviation(x ± s).The follow-up years and flight time were described by median,and the number of counts and percentages were used.Result A total of 42 patients(37 ± 9 years old,all male)were followed for a total of 49 ablation procedures.Among them,8 cases of atrioventricular reentry tachycardia(AVRT),1 case of atrioventricular nodal reentry tachycardia(AVNRT),2 cases of ventricular tachycardia(VT),atrial fibrillation(AF)and atrial flutter(AFL)18 cases,13 cases of ventricular premature beats(PVC).Immediately after surgery,41 cases were successful.Twenty-nine patients were followed up for 3 months after surgery,and 22 patients achieved clinical arrhythmia control.15 cases met the aeromedical standards.A total of 39 patients were followed up 6 months after surgery,and 34 cases of clinical arrhythmia control were achieved.Achieved 31 cases of aviation medical standards.After long-term follow-up,the average recurrence time of atrial fibrillation and atrial flutter(AF/AFL)was 21±19 months,and the number of operations was 1.3.Atrioventricular nodal reentry tachycardia(AVNRT),atrioventricular reentry tachycardia(AVRT),frequent ventricular premature beats(PVC),ventricular tachycardia(VT)have no recent and long-term recurrence,number of operations 1 time.The 37 cases were released after aviation medical identification.After the go-around period,there were no recurrences of various arrhythmia and special complications affecting flight training tasks and flight safety.After the second flight,the longest follow-up flight time was 98 months,the median follow-up period was 18 months,the flight time was 1040 hours,and the median time was 300 hours.Among them,the high-performance aircraft flight crew has a median flight time of 400 hours,the low-performance aircraft flight crew has a median flight time of 100 hours,and the helicopter flight time is 100 hours.With or without tachyarrhythmia,tachycardia and hemodynamic symptoms caused by rapid arrhythmia(obscured vision,unconsciousness,progressive aggravation of chest pain,syncope or fainting aura),etc.,can become a flight personnel with tachyarrhythmia RF indicators for postoperative evaluation of ablation.Conclusion 1.Radiofrequency ablation effectively controls arrhythmia in the treatment of tachyarrhythmias in flight personnel,with low complications,safe and effective,and can be resumed after the postoperative compliance with the release criteria;2.Six months after operation as the time point of flight identification release,in line with the clinical postoperative recovery course.3.This study provides a basis for the development of postoperative evaluation criteria and postoperative follow-up indicators for the formation of tachyarrhythmia in flight personnel.
