I had an echo that looked good other then that not to many other test
Are you fully passing out? If so then a pacemaker may be called for but if not, if you are tolerating the episodes and the nsvt is stopping within a very short time and your heart is structurally healthy then you may not need to worry but do follow up with the cardiologist on your next steps. You should at least have your heart fully evaluated. Take care and keep us posted.
Oh yea I got 5 PVCs in a row.
