Abstract: Objective To study the hypertension and abnormal electro cardiogram in rural residents.Methods Overall 10.625 subjects were collected from 15 villages of Taiyimountainous area and questionnaire survey and physical examination were conducted among the participants.The relationship between hypertension prevlaence and cardiacarrhy thmia was analyzed.Results Hypertension prevalence in the subjects was 23.25% and standardization rate was 15.28%.In residents above 15 years old,the standardization rate was 18.83%.The difference of hype rtension prevalence between men and women was not significant(P>0.05).The hypertension prevalence increased with the increase of age(χ²=2558.47,P<0.01).With the increase of blood pressure,findings of cardiac arrhythmia such as atrial fibrillation,ST-T changes,premature ventricular arrhythmia and atrioven tricular block increased(P<0.01).Conclusion The rate of ventricalar arrhythmia is higher than the rate of artrial arrhythmia among hypertention patients and increases with blood pressure in rural residents.
