Key result
A novel wearable electrode embedded in an undershirt demonstrated excellent concordance with Holter ECG for measuring total heart beats (R = 0.999) and detecting arrhythmias.
Why the study?
While 12-lead and Holter ECGs are gold standards for arrhythmia detection, the utility of a novel wearable electrode embedded in an undershirt for ECG monitoring and arrhythmia detection was unknown.

A novel wearable electrode embedded in an undershirt provides equivalent accuracy to a Holter ECG for monitoring heart rate and detecting arrhythmias, offering a less invasive and user-friendly option for long-term monitoring.
May aid post-ablation monitoring; hypothesis-generating and requires larger validation before clinical adoption.
BACKGROUND: A 12-lead electrocardiogram (ECG) and Holter ECG have been established as gold standards for detection of arrhythmias. Recently, wearable ECG monitoring devices have been available. Our purpose of the present study was to investigate whether a novel wearable electrode embedded in an undershirt is useful for ECG monitoring and detection of arrhythmias. METHODS: We studied 31 consecutive hospitalized patients who underwent catheter ablation of tachyarrhythmias. Patients equipped a wearable electrode and a lead CM5 of Holter ECG simultaneously, and total heart beats, maximum heart rate (HR), mean HR, minimum HR, detections of arrhythmias, such as atrial fibrillation, non-sustained ventricular tachycardia, and premature ventricular contractions (Lown's grade >II), were compared between the two methods using a Holter ECG analysis software. RESULTS: Median recording time of ECG by wearable electrodes was 12.6 hours. Strong correlations between the two methods were observed in total heart beats (R = 0.999, P <0.001), maximum HR (R = 0.997, P <0.001), mean HR (R = 0.999, P <0.001), minimum HR (R = 0.989, P <0.001) and QRS duration (R = 0.900, P <0.001). Bland-Altman analysis showed excellent concordance between each parameter measured by two methods. In addition, the detection of atrial fibrillation (nine events), non-sustained ventricular tachycardia (two events), and premature ventricular contractions of Lown's grade >II (five events) were concordant in two methods. In addition, there were no significant difference in parameters of time-domain and frequency-domain analyses of heart rate variability between the two methods. CONCLUSIONS: The usefulness of a novel electrode embedded in an undershirt is equivalent to that of a Holter ECG in monitoring the ECG and detection of arrythmias.

Amami et al. (2022) conducted an observational in Tachyarrhythmias (n=31). Wearable electrode embedded in an undershirt (Plum SENSE) vs. Holter ECG was evaluated on Total heart beats (R = 0.999, p=<0.001). A novel wearable electrode embedded in an undershirt demonstrated excellent concordance with Holter ECG for measuring total heart beats (R = 0.999) and detecting arrhythmias.
