Abstract
Objectives: Coronary heart disease (CHD) is the leading significant cause of mortality worldwide. Previous studies have shown that the presence of fragmented QRS (fQRS) in the electrocardiogram (ECG) can be associated with scars in myocardial tissue. This topic seems specific and focused on a particular aspect of cardiology research. It may be of interest to researchers and clinicians in the field of cardiology. This study aimed to investigate the effects of fQRS on diastolic parameters using Tissue Doppler Imaging (TDI) in patients with acute coronary syndrome (ACS) and normal systolic function.

Methods: In this periodic-analytical study, 100 patients (50 with fQRS in superficial ECG and 50 without fQRS) were evaluated by the diagnosis of ACS and ejection fraction (EF) value of over 50 in Seyed al-Shohada Hospital during 2020-2021. The diastolic parameters between these two groups were compared using the Tissue Doppler method.

Results: A total of 100 patients were studied, of which in the first group, 26 (52%) were male and 24 (48%) were female. Also, in the non-fQRS group, 25 (50%) were male, and 25 (50%) were female. The mean age scores for fQRS and non-fQRS groups were 5.10±6.58 and 4.10±3.57 years, respectively. TDI was not significantly different in both groups, yet the mean Tissue Tei Index was less in the non-fQRS group (0.6±0.15 vs. 0.55±0.11, p=0 >005).

Conclusions: The results revealed no significant relationship between Tissue Doppler Indicators in the groups with and without fQRS.
