Lbbb
My LBBB does not present any symptoms, so when I exercise, my heart rate increases normally and then drops when I stop. Consequently, I have never been advised to wear a monitor during exercise and only do so during my annual exercise ECG under the supervision of the CAA medics.
What are the physical effects when your heart rate suddenly cuts back to 50? Can you continue the exercise, or are you forced to slow down because your heart cannot supply enough oxygenated blood to sustain the effort?
