| Summary: | Background: Diabetes mellitus (DM) is a chronic metabolic disorder significantly associated with cardiovascular complications. Electrocardiographic (ECG) abnormalities are common in patients with type 2 diabetes (T2DM) and can serve as early markers for cardiovascular risk. Objective: This meta-analysis aims to evaluate the impact of T2DM on electrocardiographic changes, focusing on major ECG abnormalities, fragmented QRS (fQRS) complexes, and prolonged corrected QT (QTc) intervals. Materials and Methods: A systematic review of observational studies published between 2017 and 2022 was conducted using databases such as PubMed, Web of Science, Cochrane Library, Embase, and ClinicalTrials.gov. The inclusion criteria required studies to focus on patients with T2DM and report ECG changes. A total of 13 studies comprising 25,530 participants met the criteria and were included in the meta-analysis. The statistical analysis was performed using RevMan 5.4 with a random-effects model. Results: T2DM patients were 1.74 times more likely to develop major ECG abnormalities than non-diabetic individuals (crude OR = 1.74, 95% CI = 1.17–2.57, <i>p</i> = 0.006). The prevalence of fQRS complexes was significantly higher among T2DM patients (crude OR = 2.48, 95% CI = 2.09–2.957, <i>p</i> < 0.00001). Additionally, T2DM patients exhibited a higher likelihood of QTc interval prolongation (crude OR = 1.38, 95% CI = 1.09–1.74, <i>p</i> = 0.008). Conclusions: This meta-analysis demonstrates that T2DM patients have a significantly higher risk of ECG abnormalities, including major changes, fQRS complexes, and prolonged QTc intervals. Regular ECG monitoring is essential for early detection and management of cardiovascular risks in T2DM patients. |
