Also, an electrophysiologist IS a cardiologist, with an additional couple years of specialization. Ablations are still considered invasive surgery and they do carry some risks.
Now if you told me PVCs are not scary, I'd probably agree. I get 5K-30K of them every day, depending on some factors. Definitely not up there with Afib.
It's clearly possible, as is the risk of death from pulmonary embolism after flying on a plane - but that doesn't mean that we should screen all flyers for pulmonary embolism.
This site has a useful risk calculator for risk of complications of a-fib: http://www.zunis.org/FHS%20Afib%20Risk%20Calculator.htm
Could you expand on that? Radio-frequency ablation is not something that is done the same day.
That said, I would not have the same casual attitude of parent. Poking holes in your heart, no matter how small, is not without risk. And it is my understanding that most people stay overnight after an ablation.
