A study of electrocardiographic changes in type 2 diabetes mellitus patients

Abstract

Diabetes, which is known since the early I century, is an illness with a large number of types and affected people and it has become one of the global problems. From them, type 2 diabetes, which has many affecting factors, is one of the most common types of diabetes. The objective of our study is to determine the sugar levels of patients with Type 2 diabetes through a non-invasive method which does not cause infections, that is the electrocardiogram (ECG). The study lasted for two days. There were two parts of the experiment: one was carried out on an empty stomach until 8:00 on the first day, and the second one was done two hours after eating on the second day until 20:00. In order to compare the results the sugar levels of 20 women and 32 men with Type 2 diabetes were determined with an electrocardiogram and a glucometer. Data on gender, age, overweight, duration of illness, smoking habits, income, parental history of diabetes, early cardiovascular disease (CVD) was collected accordingly. The results of the study show that in patients with Type 2 diabetes the S, T, ST, QTc, QRS intervals of electrocardiogram (ECG) change and sugar levels are higher in the evening than in the morning.
