Stay fit: I'm simply glad he's exercising & hope he keeps it up. Many people have a left bundle branch block for no reason -- i think it's a minor developmental variant. I'm also going to assume that these are common palpitations and there's no reason to think it's a channelopathy or v-tach. Trusting he's not overdoing caffeine. I'm betting no cause will be found and that these will not be a problem.
