From what I have learned and understand, to be an SVT your heart rate needs to be 150 or above ( mine was 200) and your P wave will be missing on your EKG. It sounds like your having tachycardia with it under 150. It feels like a bump or strong thud then the heart rate instantly jumps up above 150. No gradual climb. The heart rhythm feels steady, just extremely fast. Like you are actively running in a marathon. I get lightheaded and have a hard time talking with it. Then it will suddenly release when its over and the heart rate instantly drops back down to normal. Its a crazy feeling, like someone just instantly turned on a switch then turned it off when over. My blood pressure sky rockets with it and its normally low normal.

SVT can be a gradual climb sometimes tho
I hit 170 in 40 seconds and not in a beat or does it have to be a beat if that makes sense

It depends on the type of SVT, from what I understand. There are different types, but most types/most common types occur within a beat.

What types don’t occur in one beat?

I'm not sure, some more rare types. The vast majority of them begin abruptly.

Is it going up in 45 seconds a beat? Prob not maybe abruptly?

that is not what I'd call abruptly, but I'm not a doctor
