I have tried ACE inhibitors, Alpha blockers, and beta blockers.. but I need beta blockers for an arrhythmia. I wanted to hear some opinions on using beta blockers on cycle. They reduce the hearts demand for oxygen, so does that mean O2 levels decrease? If heart rate slows after taking a beta blocker, does that mean the body isn’t getting the oxygen it needs? Seems that heart rate increases for a reason (greater oxygen demand). When I’m on cycle I’m always out of breath, but after I take metoprolol I feel fine.
