目的探讨窦性心率震荡对急性病毒性心肌炎患者死亡的预测价值。方法回顾性分析急性病毒性心肌炎患者98例与对照组30例。急性病毒性心肌炎患者存活组75例与死亡组18例的24h动态心电图。比较各组间HRT的TO和TS。结果①与对照组TO、TS(-6.2±3.7)%、(13.4±5.6)ms/R-R间期比较,急性病毒性心肌炎组TO高(-3.4±6.3)%TS低(6.2±6.0)ms/R-R间期,差异有统计学意义(P<0.05、P<0.01);②与急性病毒性心肌炎存活组TO、TS(-5.3±5.8)%、(7.1±2.2)ms/R-R间期比较,死亡组TO值高(-2.3±4.2)%、TS低(5.5±3.9)ms/R-R间期,差异有统计学意义(P<0.05)。结论HRT与急性病毒性心肌炎患者的死亡及预后有关,可作为急性病毒性心肌炎患者预后的预测因子。
Objective To investigate the predictive value of sinus heart rate turbulence in the death of patients with acute viral myocarditis. Methods A retrospective analysis of 98 patients with acute viral myocarditis and control group of 30 patients. 24h dynamic electrocardiogram in 75 survivors and 18 death patients with acute viral myocarditis. TOT and TS of HRT were compared between groups. Results Compared with the TO and TS (-6.2 ± 3.7)% and (13.4 ± 5.6) ms / RR intervals in the control group, the TS of the group with acute viral myocarditis was (-3.4 ± 6.3)% TS lower (6.2 ± 6.0) ms / RR interval, the difference was statistically significant (P <0.05, P <0.01); ②Compared with the interval of TO, TS (-5.3 ± 5.8)%, (7.1 ± 2.2) ms / RR in survivals of acute viral myocarditis , The TO group in the death group was (-2.3 ± 4.2)%, the TS was (5.5 ± 3.9) ms / RR interval, the difference was statistically significant (P <0.05). Conclusions HRT is related to the death and prognosis of patients with acute viral myocarditis and can be used as a predictor of prognosis in patients with acute viral myocarditis.
