is an ECG reading with QTc of 469ms normal?

[Andyroo66]

Hi in 2006 I had an ECG done that I have recently found. It shows the QTc interval is 469ms but was reported as "normal". I was under the impression that anything above 440-460ms is prolonged or is it not that simple? Reason I ask is I am looking into making a claim that the ECG should have been interpreted as "warranting further investigation".

Last year I was diagnosed with LQTS following an excercise test but have no symptoms black out etc, suspect an over-zelous Cardiologist. Genetic testing didnt show anything but they might want to test more family members.

Thanks very much

Mine was 470ms when I was on 2 QT lengthening drugs, Flecainide and Sertraline.

I had to stop the Sertraline to shorten it but have not yet had it checked.

My research shows that it becomes worrisome when it gets to 550ms.

It is not known at what point exactly where dangerous arrhythmia occurs as it is after the fact like unexplained cot deaths.

Some suicide patients have survived with QTc of 600 to 700ms.

Let me know what the doctors say please.

Even when I’m having angina attack my ECG shows normal, so did my brothers even tho he was having a HA, also took 3 bloods tests for him to show anything, he had stent fitted 99% blockage,

That is what happened to me ,Chest , back and neck pain , ECG normal, but blood test showed showed a different story, I had a stent fitted 2 days later

Have been told by many nurses that ECG’s are not accurate, I had my last angiogram in 2017 was told stents have blockages and another blockage underneath a stent, my angina is getting g worse keep ringing up but all I get is your on the waiting list about 4 mths for another angiogram, they did this to my dad, he then had 3rd massive heart attack and suffered 5 mths in heart failure before he died bless him
