Does anyone know if a cpet is accurate if you are paced. I'm mostly curious because they did not change my settings for the test so I went into pacemaker weinkebach before I hit anerobic threshold. I am pretty sure they use you max heart rate to calculate you VO2max, and mine would show an artificially low heart rate due to the wienkiebach(I am sure I prob misspelled that twice). I had to show it to the nurse post test and explain because during the test she exclaims "wow your heart rate went way down now, your doing great". I had already explained upper rate limit with her prior to test and she had already forgotten. Or course my atria were going twice as fast likely putting that rate between 200-220bpm if it was true 2:1.
