经过对276例老年住院病人动态心电图（DCG）观察．我们发现老年人室早发生率为70％，中年入室早发生率45％，且心脏病组和对照组室早发生率分别为85％和55％，心脏病组显著高于对照组（P＜0．01）．五种老年常见疾病冠心病、肺心病、高心病、慢性支气管炎、高血压室早发生率分别为91％、82％、65％、58％、64％，在各疾病中室早发生率差异显著（P＜0．01）在各级室早中，以Ⅰ级室早发生率最高78％。Ⅱ级次之13％，Ⅲ级7％，Ⅳ级2％，未见Ⅴ级．在三种心脏病冠心病、肺心病、高心病间比较，室早级数发生率差异显著（P＜0．005）．提示老年人的室性心律失常与年龄、疾病的种类有着密切联系．本研究对临床有一定临床指导意义．
After 276 cases of elderly inpatient ambulatory electrocardiogram (DCG) observation. We found that 70% of senile patients had early onset and 45% of middle-aged patients were admitted early, and 85% and 55% of patients in heart disease and control groups were earlier than those in control group <0.01). Coronary heart disease, pulmonary heart disease, heart disease, chronic bronchitis, and early occurrence of hypertension were 91%, 82%, 65%, 58% and 64% respectively in five common diseases of the elderly. Significantly (P <0.01) in all stages of room early morning to Ⅰ grade room early incidence of up to 78%. Ⅱ grade 13%, Ⅲ grade 7%, Ⅳ grade 2%, no Ⅴ grade. In the three kinds of heart disease, coronary heart disease, cor pulmonale, hyperglycemia, the incidence of premature ventricular dysfunction was significantly different (P <0.005). Tip elderly ventricular arrhythmias and age, the types of diseases are closely linked. This study has some clinical significance in clinical practice.
