  Purpose
To assess the ability of common genetic variants in aggregate to predict drug-induced QT prolongation in patients being loaded with dofetilide or sotalol, and validate the feasibility of using a smartphone device for measuring QT interval.

Condition Intervention
Long QT Syndrome Drug Toxicity Drug: Dofetilide and/or sotalol

Study Type: Observational
Study Design: Observational Model: Case Control
Time Perspective: Prospective
Official Title: Genetics of QT Prolongation With Antiarrhythmics

Further study details as provided by Christopher Newton-Cheh, MD, Massachusetts General Hospital:

Primary Outcome Measures:
  • QT interval [ Time Frame: QT intervals will be measured on each ECG obtained during the index hospitalization ]
    QT interval will be measured on electrocardiograms, and recorded in the case report form


Secondary Outcome Measures:
  • Successful drug initiation [ Time Frame: Patient will be followed for the duration of the hospitalization, which is on average 3 days ]
    This outcome will be recorded in the case report form


Biospecimen Retention:   Samples With DNA
Blood samples for DNA extraction

Estimated Enrollment: 500
Study Start Date: January 2014
Estimated Study Completion Date: January 2019
Estimated Primary Completion Date: January 2019 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Dofetilide patients
Patients admitted for dofetilide initiation
Drug: Dofetilide and/or sotalol
This is an observational study of patients receiving Dofetilide and/or sotalol as part of their routine clinical care. Patients receiving either of these medications will be compared with population controls for genetic analysis.
Other Name: Tikosyn
Sotalol patients
Patients admitted for sotalol initiation
Drug: Dofetilide and/or sotalol
This is an observational study of patients receiving Dofetilide and/or sotalol as part of their routine clinical care. Patients receiving either of these medications will be compared with population controls for genetic analysis.
