BACKGROUND: To assess the diagnostic accuracy of a single-lead portable ECG device for measuring QTc-intervals in comparison with a standard 12-lead ECG. METHODS: Adult patients visiting the cardiology outpatient clinic for a 12-lead recording were also measured with a portable single-lead ECG recorder (HeartcheckTM). QTc-intervals were determined by two cardiologists. Perfect agreement was defined as a limit of </=10 ms between the two measurement methods. RESULTS: Hundred one ECGs were recorded. QTc-interval mean differences between the two measurement methods was substantially outside our definition of perfect agreement (-31.9 [SD+/-41.3] ms). CONCLUSION: In conclusion, the Heartcheck single-lead ECG device is not accurate for measuring QTc-intervals.
