The ECG changes in various comorbidities with hypertension and without hypertension

Background Hypertension is the commonest cardiovascular disorder posing a challenge to the societies in socioeconomic and epidemiologic transition. In India, Cardiovascular Diseases (CVDs) are estimated to be responsible for 1.5 million deaths annually. Indeed, it is estimated that by 2020, CVDs will be the largest cause of mortality and morbidity in India. To present study is designed to evaluate the variation of blood pressure and ECG wave forms among people hypertension with co morbidities (study group) and controls.

Methods The study included 50 people comorbidities with hypertension and 50 controls, each between ages 30-40 years from general population, and also from Medicine outpatient department, KIMS and RF Amalapuram. Detailed history from subjects, blood pressure (sitting position) and electrocardiogram was recorded during resting state in supine position. The ECG results were evaluated for various parameters like heart rate, P wave, PR interval, QRS complex etc.

Results There was significant increase in heart rate, systolic blood pressure as well as diastolic blood pressure in study group when compared to controls. Decrease in PR interval, decrease in QT interval, decrease in QTc interval, decrease in QRS axis in smokers when compared to controls.

Conclusions There was significant increase in heart rate in study group (smokers, diabetic) when compared to controls. There was significant increase in systolic blood pressure as well as diastolic blood pressure in study group (smokers, diabetics) when compared to controls. There was significant decrease in PR interval in smokers when compared to controls. There was significant decrease in QT and QTc interval in smokers when compared to controls.
