yes, they are long. Furtunately the one we did yesterday took less then 2 hours. With the trans-septal (right-left peircing with a needle through the right ventricle-left venticle) they do give you general anesthea because it is vital that you DON'T MOVE as the find the PFO (the hole in your heart that closes when you were born... this is where they peirce the needle through... if the miss... it's too the OR in a hurry). Our patient yesterday took only 1 sec of burning to arrest his A-fib/Aflutter. However he comes back again today for a pacemaker upgrade
oh well job security for me
I sedate about 30% of the EP studies and pacemakers. We don't use anestheasia unless they are very sick (ASA class 4).
The PVC's can be treated with a Beta-blocker later like LOPRESSOR if they are to many.
