hi, my name is Lena. I have two leaking heart valves. The one to my lung is +1 and the one to my heart is +2. My cardiologist checks me every 3 months for an enlarged heart. This morning at Bible study, I began shaking (I have tremors, vertigo, and lupus) even after tremor meds, I began to sweat. A woman there is an ICU nurse. She checked my pulse and said it was extremely fast and irregular. I had very minor chest pain. I took another low dose aspirin, I had taken one 3 hours earlier as prescribed, and another klaunapin, which is for my tremors. I still feel a slight pain above my left breast. I have a cardio apt next Monday. Is this the sign of an enlarged heart or is something else wrong here.
