NCT02241252 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 29

No results posted yet for this study

Summary

This study will validate the recording accuracy of a specific electrical interval of the heart, the QT interval, between an iPhone rhythm strip recording and a traditional 12-lead electrocardiogram (ECG). These measurements will occur in hospitalized patients that are starting either sotalol or dofetilide, since both of these medications can prolong the QT interval.
