I'm new to this website and thought I would post a question on here. I've recently started feeling palpitations in the center of my chest that sometimes make me cough. I went to my doctor and she had me wear a 24 hour heart monitor. When the results were read, she immediately sent me to a cardiologist. He does see where the results were not normal and did an Echo test which showed I had good structure to my heart. Today I went for a Nuclear Stress Test and everything came out fine.......there are no blockages. The last test he wants me to take is an MRI, but I'm waiting for the hospital to call me to set up an appointment. I have never smoked, my EKG's are fine, I do not have high cholesterol and thyroid and various bloodwork came out fine. I don't drink coffee or really any caffeine to speak of....I'm a HUGE water drinker. I'm happy things are looking good so far, but I'm wondering if anyone else has had symptoms like this. The palpitations and coughing can definately interrupt my day to day life.......and I have admit they do scare me because they happen quite frequently. Does this sound familiar to anyone on here? Thanks so much for your help.
