Abstract

Background and objective:  The result of electrocardiographic survey in elderly hypertensive patients in Thailand has limited information.  This study aimed to investigate the characteristics of electrocardiogram (ECG) in elderly hypertensive patients. 

 Methods:  This research was a survey study.  The data was collected during September to October 2018. The population consisted of 165 elderly hypertensive patients treated at Tha Nang Ngam, the primary hospital. The number of sample size was 117 cases calculated from the Taro Yamane formula, the error of 0.05. The instruments in the study were the demographic data form, the basic physical examination form and electrocardiography machine.

Results: Most of elderly hypertensive patients were 75 females (64.1%), mean age 68.8±7.0 years, mean body mass index 25.2±4.5 kg/m2, the average of systolic blood pressure 135.7±14.9 mmHg, the average of diastolic blood pressure 75.8±11.0. The normal ECG was found in 65 elderly hypertensive patients (55.6%).  The most abnormal ECG were Left ventricular hypertrophy 13 cases (11.1%) and Inverted T-wave 13 cases (11.1%), Sinus bradycardia 8 cases (6.8%).

Conclusion:  The normal ECG was detected in the major group of elderly hypertensive patients.  The abnormal ECG were Left ventricular hypertrophy and Inverted T-wave, Sinus bradycardia, respectively.
