I was with a friend & she smokes. She smoked in a closed room i was in. It was only one cigarette. Will second hand smoke harm my heart? I have svt.

In brief: Smoking

One time inhalation of cigarette smoke is unlikely to cause a problem. Chronic bystander smoke exposure is a different matter. With respect to svt there is a small possibility of a problem with a one time inhalation.
It is always good to avoid smoke, first or second hand.
