The diagnosis and management of increasing numbers of patients with chronic diseases in the community require new technologies and strategies of care. We have used a new wireless cardiorespiratory telemonitoring system to monitor 14 elderly patients with a variety of chronic diseases at home. The electrocardiogram (ECG), heart rate and variability, and breathing were recorded on two separate occasions for 24 h. There was no difference in the data recorded when a research nurse applied the monitoring system and when the patients applied it themselves. The ECG and heart rate were recorded for 98% of the monitored time, and the frequency and periodicities of breathing were recorded for 74% and 61% of sleep and rest time by visual and automatic analysis, respectively. The results show that 24 h activity and cardiorespiratory telemonitoring can be performed by elderly patients at home. Significant unsuspected abnormalities of breathing and heart rhythm, amenable to treatment, were also detected.
