Pacer and VO2 max
I have been running (jogging) and am trying to increase my endurance and pace so that I can complete a 10k. I have found running late in life, after I got my CRT-P about 18 months ago due to a heart rate of 30. I was in atrial flutter, had an ablation which resulted in a Wenkebach. I have lost 40 pounds and run/jog 3-4 a week. My EP refuses to increase my maximum HR above 140, based solely on my age.I have had a stress test and show no signs of ischemia. I use a Garmin watch to time my pace and heart rate. I cannot seem to increase my pace without becoming short of breath, and my VO2 max has topped out at 33. Any advice on how to advocate for an increased rate to hopefully allow me to run faster?
