Why is my HR 110 at rest and 70 on exertion ? I have HF many years and have a CRTD.
I notice that my BP is low when my pulse is high which makes it difficult to take beta blockers. Tried Ivabradine which didn't work. Awaiting Holter & Echo. Only noticed this particular problem last few weeks. CRTD settings not been changed. 10 min walk reduced HR by 40bpm but only lasts about 45 mins then it's back up to 110. Seems odd. Maybe a simple explanation ?
