Palpitations: It is unclear if what you are describing is normal or not. It depends on what your heart rhythm (electrical pattern on ekg) looks like at the fast heart rate, if you have symptoms and what your exercise capacity is. A cardiologist and a heart monitor can help sort this out. Hope that helps!
