. I have similar symptoms. I was put on kholter montior for 24hrs and diagnosed as have PAT and PCV.
It is often begnin and in certains cases can be life threatening is you have a heart disease
. Stop the caffeine, tea, chocolate and take magnesium
, potassium and calcium it helps to reduce it. Drink a lot of water and stop stressing! All these helped me to reduce it
