Using an iPhone ECG to Monitor the QT Interval on Dofetilide and Sotalol Patients

간략 요약

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.
