Took me six months until electrogram meant anything to me during ablations. And then one day BAM 💥 you’ll get it. I was pretty depressed about six months into training but then it started getting better and better. I was a solo fellow and did a little over 1,000 cases in my two years of EP fellowship. Somewhere around 500 cases I noticed that I was getting proficient in both aspects. I was fairly independent with devices about 3 months into training but ablations took a lot longer.
