We got propably lqt syndrome 1 or 2 in our family. We undergo genetic tests these days. It was discovered incidentally on my routine ECG, than confirmed on another. I´m now 25, I had only 2 presyncopes/no collapse up to now.I have been played strenous sport all my life including soccer, basketball, snowboarding, I played ice hockey for 10 years. Almost every time I was even the most active player on the pitch. Plus I had experienced stuff like fights, big stresses and big parties with lot of alcohol or marijuana, always without problems.
My qtc is around 460-470, my cardio said it´s not that dangerous unless it´s under 500 ms. I´m not takin beta blockers so far, but he recommended me to restrict sport activities.
I know, you can give me only informative advices, which I must consult with doc personally. I just wonder what do you think about all of it? Do you think I still could be in danger despite my age and all things above? But mainly, which treshold for the heart rate during exercise you could recommend me?
Your QTc is too long and you are at risk. By the way, it is more dangerous when your QTc is >500! The best way to go forward is to check your heart rate etc. with a stress ECHO. As far as management is concerned, it depends on the results.
