CArdiac REhabilitation for Building Exertional heArt Rate for Chronotropic Incompetence in Long COVID-19

Exercise prescriptions will be based on the heart rate performance during the baseline CPET. The intensity of the exercise prescription and level of monitoring will be tailored to the individual participant's performance on their baseline CPET according to guidelines. Exercise will be prescribed by a Cardiac Exercise Physiologist in accordance with standard cardiac rehabilitation protocols with special attention to post-exertional malaise. Resistance exercise activities will also be incorporated. Recumbent exercise will be utilized based on assessment by exercise physiologist and patient. Dietary counseling, smoking cessation counseling for smokers, and medication counseling will be incorporated according to standard cardiac rehabilitation protocols. Most participants will participate in a hybrid approach (12-16 sessions in person), but participants will be allowed to select a fully in-person approach (36 sessions).
