I wear a loop monitor looking for AFib. I had palpitations BP 113/07 178 bpm. Dr recommends a wire to the rt ventricle to zap a faulty beat. Is ok?

Suppose so. If you have been seeing an electrophysiologist and he says you need ablation he is probably correct. A HR of 178 bpm is pretty fast for your age. You should be asking him for a better explanation of why this should be done.
