Brief Title
Determine the Incidence of Long QT Amongst a Large Cohort of Subjects Diagnosed With Unilateral or Bilateral Sensorineural Hearing Loss.
Official Title
Long QT & Hearing Loss Prospective Study Registry
Brief Summary
The purpose of this study is to determine the true incidence of long QT (LQT) amongst a large
cohort of subjects diagnosed with unilateral (right/left) or bilateral sensorineural hearing
loss.
Detailed Description
The purpose of this study is to determine the true incidence of long QT (LQT) amongst a large
cohort of subjects diagnosed with unilateral (right/left) or bilateral sensorineural hearing
loss.
The goal of this study is to answer the following questions:
1. What is the incidence of an abnormal ECG (QTc > 450 msec) in neonates greater than a
week of age with either unilateral or bilateral Sensorineural hearing loss?
2. What percentage of neonates greater than one week of age with either bilateral or
unilateral sensorineural hearing loss and an abnormal ECG have an identifiable genetic
mutation?
3. What is the incidence of an abnormal genetic mutation consistent with long QT regardless
of the ECG in neonates with bilateral sensorineural hearing loss?
Study Type
Observational
Primary Outcome
The incidence of an abnormal ECG (QTc > 450) in neonates greater than a week of age with either unilateral or bilateral sensorineural hearing loss
Secondary Outcome
In neonates > 1 week of age with either bilateral or unilateral sensorineural hearing loss and an abnormal ECG, percentage have an identifiable genetic mutation
Condition
Sensorineural Hearing Loss
