Analysis of eCG in 400 AIDS patients at different age grades

Objective To study the Electrocardiogram (ECG) changes in AIDS patients at different age grades. Methods The ECG of 400 AIDS patients at different age were analyzed retrospectively. Results (①)The rate of abnormal ECG in the age group of 46 ～50 years was significantly higher than 11 ～ 15(P =0. 008) ,21 ～25( P = 0. 041 ),31 ～ 35 ( P = 0. 022 ),41 ～ 45 ( P = 0. 001 ) and 51 ～ 55 ( P = 0. 047 ) years groups respectively. (②)The rate of bradyarrhythmia in the age group of 46 ～ 50 years was significantly higher than 31 ～ 35 (U = 2. 44) ,36 -40( U = 2. 18 ) ,41 ～ 45 ( U = 2. 57 ) years groups ( P ＜ 0. 05 respectively. (③)The rate of left atrial and ventricular hypertrophy in 11 ～ 15 years group was significantly lower than the age groups older than 46 (except for 51 ～ 55years group) ;those aged ＞60 had higher atrial and ventricular hypertrophy rate than 36 ～40,41 ～45 and 51 ～55years groups ( P ＜ 0. 05 respectively). Conclusions AIDS patients at all ages may present abnormal ECG, which is positively correlated with age. Key words: Human immunodeficiency virus;  AIDS;  Age grades;  Electrocardiogram
