Clinical features and related factors of elderly arrhythmia

Objective To study the clinical characteristics and the related factors of elderly arrhythmia.Methods 658 elderly patients with cardiac arrhythmia who were confirmed by the conventional ECG or Holter were chosen.Their arrhythmia type and related factors were analyzed.Results Among 658 cases of elderly patients,atrial fibrillation accounted for the highest rate(19.0％,241/1 266),followed by ventricular contraction of 17.0％ (215/ 1 266).The detection rate of sinus arrhythmia,ventricular arrhythmia was significantly different between ≥ 80 age group and ＜ 80 years old group of elderly patients (P ＜ 0.05).The 658 elderly patients had a total of 976 kinds of underlying disease,every elderly patient had one or more than one underlying disease.The top five underlying diseases were hypertension 18.6％ (182/976),coronary heart disease 16.9％ (165/976),chronic obstructive pulmonary disease 15.1％ (147/976),diabetes 14.3％ (140/976),malignant tumors 11.1％ (108/976),other underlying disease 24.0％ (234/976).In ≥ 80-years-old group,50.8％ (123/242) patients complicated with a variety of underlying diseases,which was significantly higher than that of ＜ 80-years-old group 24.5％ (102/416) (P ＜ 0.05).Conchluion Elderly patients due to the presence of different levels of underlying diseases and function degradation,prone to a variety of different types of arrhythmias,which should attract enough attention in clinical diagnosis and treatment,early detection and early intervention,in order to improve the quality of life of elderly patients.
