@gift440 yes NSVT is different from SVT! I am glad that you are having what seems to be good care.

One of my kids may have Ehlers Danlos and nearly faints a lot, often in the heat. Their atria are enlarged and they are just being evaluated. In their teens their resting heart rate was 140, discovered in a physical education class. (I have afib, the common cold of cardiology! My high heart rate is SVT though.)

ps very wise to avoid too much tracking due to the anxiety it can cause!!

Would you feel reassured with a pacemaker and defibrillator? Are you thinking of going ahead with that?
