Holter Monitor: 24-Hour Monitoring

Holter Monitor: 24-Hour Monitoring

Holter monitoring is a continuous electrocardiography (ECG) recording that tracks the heart's electrical activity over an extended period, generally 24 to 48 hours. This noninvasive diagnostic tool detects irregular heart rhythms that may not be captured during a standard ECG performed in a clinical setting.DeviceThe Holter monitor is a portable, small device connected to several electrodes on the patient's chest. These electrodes detect the heart's electrical signals and transmit them to the...

Area of Science:

Digital health technologies
Psychiatric outcome tracking
Mobile health interventions

Background:

Electronic tracking improves adherence and data integrity compared to paper methods.
An unmet need exists for automated web-based platforms for psychiatric outcome tracking.
Mood 24/7 was developed as an automated, SMS-based mood tracker for psychiatric patients.

Purpose of the Study:

To assess the accuracy and validity of the Mood 24/7 electronic mood-monitoring platform.
To evaluate Mood 24/7's performance in an outpatient psychiatric setting.
To validate Mood 24/7 for future clinical trials on digital mood-tracking benefits.

Main Methods:

Pilot study utilizing retrospective chart review of 9 depressed outpatients.
Comparison of Mood 24/7 daily mood ratings with psychiatrist's clinical assessment over 36 weeks.
Mixed model analysis comparing weekly Montgomery-Åsberg Depression Rating Scale (MADRS) scores with Mood 24/7 scores.

Main Results:

High adherence rate of 97.2% for digital mood reporting over 36 weeks.
Significant correlation (r=0.86, P<.001) between Mood 24/7 scores and psychiatrist's assessment.
Significant concordance (intraclass correlation=0.69, P<.001) between MADRS and Mood 24/7 scores.

Conclusions:

Mood 24/7 is a valid instrument for longitudinal mood assessment.
The platform provides a convenient, simple, and noninvasive method for tracking mood.
Findings support the use of Mood 24/7 in outpatient psychiatric clinical settings.
