ECG monitoring duration and arrhythmia detection
The patients or their families had no difficulty attaching the ECG
device. A median 57 hours (range: 20–179 hours) of ECG monitoring per
patient was performed. Figure 4 shows the relationship between
the prescheduled ECG monitoring duration and the actual ECG monitoring
duration for each patient. Monitoring the ECG was performed as planned
in most cases. Figure 5 shows a representative case of ECG
monitoring. By utilizing the postal delivery service, this patient did
not need to visit the hospital to undergo the long-term ECG examination.
Arrhythmic events were detected in 8 of the 25 patients (32%), atrial
fibrillation (AF) in 5 patients, atrial tachycardia in 2 patients, and
frequent premature ventricular contractions in 1 patient.
