title: Cardiac arrhythmia in geriatric patients with organic dementia.
abstract: Cardiac arrhythmia and ST segment depression was analyzed with long-term ECG registration (LTER) in 36 patients with organic dementia aged 69-96 (mean 84) years and 27 patients without dementia or current heart disease aged 68-93 (mean 83) years. In the dementia group we found a higher prevalence of atrial fibrillation (p = 0.0131), ventricular tachycardia (p = 0.0156) and gaps (p = 0.0347) in comparison with the reference group. Ventricular and supraventricular extrasystoles were frequent in both groups. There was no difference in the prevalence of ST segment depression between the two groups. In conclusion we found an increased prevalence of atrial fibrillation, ventricular tachycardia and gaps in the dementia group in comparison with the reference group.
