Good news my cardiac doctor sees no evidence of heart failure and reduced my stuff to 1 from 3. I did this with stuff, exercise, eating clean and prayer. The stuff I am on is eliquis it limits how fast my heart will beat. The problem is I want to do HIIT. The fastest HR I can get is 117 BPM. Can I get a proper HIIT at 117 BPM? If not what other forms of cardio should I look at?
