It's really a good sign that your blood pressure got that high!
It's a sign that your heart works excellent! The danger with arrhythmias is not high blood pressure, it's LOW blood pressure, if your heart rate is too high, the pumping capacity is reduced and you will faint. Unless you have hemodynamic capacity to keep up the blood pressure despite the high heart rate. You do.
It's not easy to say what was going on. PSVT (AVNRT and AVRT) usually starts and stops instantly so this was probably not the case with you. That leaves two possibilities, sinus tachycardia (anxiety attack) or ectopic atrial tachycardia. They can't be differed without an EKG.
Ventricular tachycardia is ruled out, no human being could maintain that blood pressure with a VT that rapid.
If I should guess, I would guess anxiety attack (but you must decide if you were anxious!). But it's impossible for me to say. No, this won't damage your heart unless it happens daily for years :)
As most people told you, see a doctor for this.
go get a full cardiac workup outside an ER just to make sure nothing else is going on and keep track of your episodes in a log or with the Rhythm tracker here so you can see if there's a pattern or any triggers...def ask your dr about when to go to the ER, how long to wait etc
all of that sounds so familiar but I only have had PSvt....that I know that a monitor picked up
Next time it happens, go to the ER and get it caught.
That is EXACTLY what mine did over 20 years ago. I felt a flutter then it shot up to 220. However my blood pressure actually remained in the normal range. They diagnosed it as PAT (SVT) which is not life threatening. But it does drain you and I get shaky and have a headache afterwards as well. This continued to happen 4 times a year. The longest episode was the first time it happened when I had the chance to get to the ER so it was at least 30 minutes long. The rest of them have only lasted up to 5 minutes. They have diminshed each year to the point where I haven't had an episode in 2 years. (I hope I don't jnx that becase they feel horrible)
The only way to know for sure is to catch it on a monitor but if it starts suddenly and stops just as suddenly it is probably some type of svt. And, my doctor told me if I have no other symptoms other than feeling the racing heart (and being scared out of my mind) then not to worry.

Several things it could've been...you do need to see your doctor. If it happens again, I would go to the ER to see if they can catch it on monitor.
I have no idea, but you need to see a cardiologist.
