ABSTRACT
This descriptive pilot study examined if manual corrected QT (QTc)
interval measures obtained from a standard 12-lead electrocardiogram (ECG)
correlated with automated 24-hour ambulatory Holter QTc measures in 30
overweight and obese youth aged 12-17 years. In addition, we sought to
determine if a significant difference existed between the means of manual
12-lead ECG versus automated 24-hour ambulatory Holter measures. Spearman’s
rho correlation coefficient revealed there was little if any correlation
between manual 12-lead ECG and automated 24-hour ambulatory Holter QTc
measures (r = .179, p = .345). In addition, a significant difference
existed between QTc measures obtained from the manual 12-lead ECG in
comparison to the automated 24-hour ambulatory Holter measures (p = .01).
The manual 12-lead ECG and automated 24-hour ambulatory Holter analysis
methods should not be used for comparison of QTc measures in overweight and
obese youth.
