Introduction:
Although palliative care patients often undergo electrocardiography (ECG), a detailed cardiac examination is often skipped. The aim of this study was to determine the incidence of arrhythmia in older patients in need of palliative care and to evaluate risk factors for asymptomatic arrhythmias.

Material and methods:
This prospective observational study was conducted between 1 March and 1 September 2022 among inpatients in the palliative care unit of Atatürk University Faculty of Medicine Hospital. Malnutrition status was assessed using the full Mini Nutritional Assessment. Delirium was assessed at hospitalization using the confusion assessment method. Electrocardiography was performed in all patients at admission to the palliative care unit. This was followed by 12-lead, 24-hour ambulatory ECG to detect arrythmias. Electrocardiography recordings were evaluated.

Results:
The 100 patients included in the study had a median age of 78 years, and 63.0% were women. Arrythmias were detected on Holter ECG in 70 patients (70.0%). The most common were premature ventricular contraction (PVC) (56.5%) and atrial fibrillation (AF) (30.4%). There was a statistically significant negative moderate correlation between PVC load and left ventricular ejection fraction (r = –0.308; p = 0.002). Premature ventricular contraction load was significantly higher in men than in women (p = 0.018). Of the patients with AF, 17 (17.0%) were under anticoagulant therapy. Left ventricular ejection fraction differed significantly according to the presence of AF and anticoagulant use. Left ventricular ejection fraction was lower in patients with AF and anticoagulant use compared to those without AF (p = 0.001).

Conclusions:
The prevalence of arrhythmias in palliative care patients is considerable. The treatment of arrhythmias in this patient population is complicated by polypharmacy, comorbidities, and frailty.
