Abstract Objective To explore the characteristics of abnormal ECGs in elderly population aged 90 and above as well as their clinical significance. Methods A retrospective analysis was conducted on the clinical data of 204 hospitalized patients aged 90 and above. These patients were divided into two groups based on sex (114 males and 90 females). Baseline clinical data, fasting blood glucose, blood lipids, liver and kidney function, brain natriuretic peptide(BNP), ECG, and echocardiography examination results were compared and analyzed between the two groups. Results Systolic blood pressure and triglyceride levels at admission were significantly higher in the female group compared to the male group (P<0.05), while creatinine and blood urea nitrogen levels were significantly higher in the male group (P<0.05). Sinus rhythm was observed in 765% of the patients. According to the detection rate from high to low, the most common ECG abnormalities were ST-T changes (46.1%), atrial premature beats (22.1%), firstdegree atrioventricular block (22.1%), right bundle branch block (19.6%), and atrial fibrillation (13.7%) in order. The detection rates of atrial flutter, atrial premature beats, premature ventricular contraction, right bundle branch block, firstdegree atrioventricular block, and left anterior fascicular block were all higher in the male group than those in the female group. Conclusion ECG abnormalities are common in hospitalized patients aged 90 and above, primarily manifesting as ST-T changes, atrial premature beats, firstdegree atrioventricular block, right bundle branch block, and atrial fibrillation. The distribution of these ECG abnormalities differs between different sexes.
