Period of increased urination may follow chaotic heartbeats
Dear Dr. Roach: I am a woman, 74 years old and in fair health. Eight years ago I had surgery for lung cancer. The first night after, I was told I had atrial fibrillation due to the surgery being so close to the heart. I was started on metoprolol. Every now and then I would feel that my heart skipped a beat. My pulse was usually normal, and my doctors fluffed it off. I had shortness of breath to a mild degree from the surgery, but now it is pronounced on even slight exertion.
