[|Human|] I have. Few electrical issues with my heart . Have been a ablated and things are a little better . My efraction is between 35 and 40. With that said, when I exercise I have a sustained heart rate of between 210 and 230. Am I doing more harm than good?
[|AI|]  Hello! Thank you for asking on Chat Doctor! You need to be very careful and to avoid excessive physical exertion, facing your reduced LV ejection fraction. I would recommend just waking and continuing to be active that way, but no exaggerated strain. If you experience such high heart rates again, that you need to see your attending cardiologist for a comprehensive evaluation, and define a possibility of ICD implantation (if life-threatening arrhythmia results). Hope to have been helpful to you. Greetings!
