I know! Probably i am in the wrong subreddit.. but i am kinda scared, if anyone knows anything, please let me know.
Backstory: One day i was watching TV and my heart suddenly stopped (i felt it in my troath when it stopped) for 5 seconds. I was starting to lose consciousness, but then i stood up, and it restarted.
Scary experience, of course.
I went to the cardiologist to have an EKG done... but most importantly to ask what happened. He told me that what happened to me is called a "Sinus Stop". Weird...

Alright, so that is not SCA? How do I know, next time, if it is sinus stop or cardiac arrest? I mean i have 5 seconds to possibly save my life.
My cardiologist told me to not ask stupid questions like this, so reddit.. please help me.
