Many years ago when I ran in college it was much the same. But the
college doc was used to athletes and just told us it was normal for
highly trained athletes to have irregular heartbeats. My resting pulse
at the time was in the low 40s, about three beats on then a delayed
beat. Your physical sounds great.
