This answer was rated:

I had some very strong palpitations last night (which woke me up), and throughout the day I had some discomfort in mynchest (no pain), also had some milder ones. (History: I was several years ago I was told I get ectopic beats - for no apparent reason, but shouldn't worry.)
Further to advice from one of the JustAnswer doctors today it was decided it was most likely due to an expired bottle of Fluoxetine although I had only been taking it since Friday 1ml/day (20mg/5ml solution). I was also advised to have an ECG. As I am abroad now I was hoping for an explanation of what I have been told.
The ECG was in sinus rythm, no ectopic beats or other abnormalities, however the QT was at 113%. What does this mean, why could this be, is this something to worry about and what can I do about it - or do I need to do anything about it?
Hello. I'm Dr. Phil, licensed and practicing internist. Excellent service is my goal.
do you know the exact QT interval?
Customer: replied 3 years ago.

No unfortunately I was only told 113%.

I doubt it was from fluoxetine
if anything when it is expired it will be less active.
I would get a holter monitor. This is a 24 hour wearable EKG
this will track your heart rhythm and detect any abnormals
Customer: replied 3 years ago.

I had a holter and also an ultrasound on my heart a few years back and all was good (apart from the ectopic beats) so I think the doctor may be reluctant. Anyway, what does it mean and what could cause it? And is it dangerous?

what does the QT mean? is that what you are asking?
do you take any other meds?
Customer: replied 3 years ago.

Yes, and why could it be higher.

And no, no other regular medication.

women generally have a higher QT interval to begin with.
It could be a normal variation
it also could be because of dehydration or an electrolyte disturbance
I would get some blood work as well to make sure potassium is normal
