Points to be improved
The actual monitoring duration did not reach the prescheduled duration in some patients. The percentage of noises or interruption during ECG monitoring and actual monitoring time did not show any significant correlation, which suggests that the ECG monitoring quality largely differed among the patients. To improve the monitoring quality, precise oral and written instructions for patients on how to use the self-wearing ECG device should be provided for patients depending on age and level of understanding. Approximately 48% of patients felt itchiness or irritation at the sites of the electrode patches during the long-term ECG monitoring. The adhesive material of the electrode patches should be improved.
