Diagnostic accuracy of a single‐lead portable ECG device for measuring QTc prolongation

Sumario: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.
