Prolonged SVT Episodes

I was diagnosed with SVT during a nuclear stress test 3 years ago. I was having the test because of chest pain which was actually due to my gall bladder. So the SVT was sort of an accidental discovery. The doctor asked me how often I felt the flutter and at the time it was only a couple times a week for a few seconds. 48 hour monitor confirmed this. Cardiologist and heart rhythm specialist tell me it’s benign. Last year just at the point I entered menopause I started having attacks of longer duration. I was told menopause can cause this. Doctor put me on 50mg Meoprolol which helps. Still once every couple months, I’ll have an attack that lasts 5-6 hours.  I’ve never been monitored during these episodes. Feels like my heart is doing flip flips in my chest. Last night I had one and I think it was triggered by being outside at a party on a very hot evening. I had one beer - I always choose a low ABV beer because alcohol is a trigger. Sometimes the SVT leads to a full blown panic attack but I stayed calm last night. None of the maneuvers I tried were helpful. Eventually I just went to bed, fell asleep on my right side. It was gone when I woke up. I’m just wondering, if I’ve been told this is benign and my heart is healthy, should I go to the ER for a prolonged attack like this? Perhaps take a second metoprolol? Guess I should ask my doctor too! ☺️
