Does a 9-lead wireless electrocardiographic transmission device provide comparable electrocardiographic parameters to a conventional 12-lead ECG in young competitive athletes?
A novel 9-lead wireless ECG device demonstrated significant correlation with conventional 12-lead ECG for key parameters used in sudden cardiac death screening among athletes, potentially offering a more cost-effective screening method.
Effect estimate: correlation coefficient 0.878
p-value: p=0.01
BACKGROUND: The 12-lead electrocardiographic screening for the prevention of sudden cardiac death in young competitive athletes is not cost-effective and thus not routinely recommended. We investigate whether a less expensive wireless electrocardiographic transmission device can be used to screen for the prevention of sudden cardiac death in this population. METHODS: During pre-participation screening, twenty college football players underwent two electrocardiograms: a conventional 12-lead electrocardiogram and a wireless 9-lead electrocardiogram. We compared several electrocardiographic parameters (QRS duration, left ventricular hypertrophy using the Cornell voltage criteria and the Sokolow-Lyon criteria, ST deviation and corrected QT interval) to determine the correlation. RESULTS: The QRS duration, left ventricular hypertrophy using the Cornell voltage criteria and the Sokolow-Lyon criteria and corrected QT interval exhibited significant correlation between the two types of electrocardiograms (correlation coefficient 0.878, 0.630, 0.770 and 0.847, respectively with P values of 0.01, 0.003, 0.01 and 0.01, respectively). ST deviation in V1 was weakly correlated between the two types of electrocardiograms without statistical significance (correlation coefficient 0.360 with a P value of 0.119). CONCLUSIONS: Our newly developed wireless 9-lead electrocardiogram demonstrated significant correlations with a conventional 12-lead electrocardiogram in terms of QRS duration, left ventricular hypertrophy and corrected QT interval.
Cho et al. (Mon,) conducted a cross-sectional in Pre-participation screening for sudden cardiac death (n=20). Wireless 9-lead electrocardiogram vs. Conventional 12-lead electrocardiogram was evaluated on Correlation of QRS duration between 9-lead and 12-lead ECGs (correlation coefficient 0.878, p=0.01). A newly developed wireless 9-lead electrocardiogram demonstrated significant correlations with a conventional 12-lead electrocardiogram for QRS duration (r=0.878), LVH, and corrected QT interval.
