Assessment of the QT Interval Using a Smartphone ECG Device during Antiarrhythmic Drug Initiation

Overview

About this study

Obtain AliveCor ECG Recordings from subjects at the time of clinically indicated ECGs over the course their anti-arrhythmic drug loading hospital admission.
Create and refine an AliveCor algorithm to accurately measure a patient’s QT interval and heart rate corrected QTc value and validate/compare the results against the 12- lead ECGs on record.
Obtain AliveCor ECG recordings at the time of daily clinically indicated electrolyte panels to further develop and refine a Potassium screening algorithm.
