Patient survey
Figure 7 shows the results of the patient survey regarding the long-term ECG monitoring and the postal delivery service. Most patients had no difficulty sending the devices by post and no difficulty putting on or taking off the ECG device by themselves. Most patients thought the postal delivery of ECG devices could reduce patient burden in terms of going to the hospital.
Of the patients, 12 (48%) felt itchiness or irritation at the sites of the electrode patches during the ECG monitoring but could continue to undergo monitoring by slightly changing the location of the patches on the chest. Seventeen of the 25 patients had experienced conventional Holter ECG monitoring before. Sixteen of these 17 patients (94%) preferred the self-wearable ECG monitoring and the postal delivery service over the conventional Holter ECG monitoring because the Duranta device is wireless, smaller, and lighter than the conventional Holter ECG device (n = 9) and it was extremely convenient to use the postal service to return the devices rather than having to go to the hospital (n = 7).
