My husband was diagnosed with AFib about 2 years ago. His main complaint was, and still is, shortness of breath. He doesn't experience feeling any fluttering although it shows up during testing. Lately he is experiencing extreme shortness of breath after midnight which wakes him up. He states he feels restricted in taking a deep breath. All testing on his heart shows no blockage and a healthy heart otherwise. Anyone else experience this? He has an appt Monday with his cardio. We are guessing he is probably in extreme AFib during these episodes.
