I take a beta blocker, metoprolol. I’ve been on it about 4 months. No problems until recently. I’ve been going though a or of stress with a death of a close family member and trying to catch on in school work as I’m in college. My heart skips a beat quite a bit during the day. I also feel like I’m having trouble breathing sometimes. I also feel sad and anxious sometimes. I had a heart echo and they said something about 2 valves opening and closing too early, but it was only mind and not to worry about it. I’m hoping this arrhythmia goes away soon. My heart rate and blood reassure have been good. Even lower than they usually are. Any thoughts?
