I went to the ER the other night due to Fast heart rate and Anxiety. They did chest x-ray and blood test and ekg. All was normal. they said my heart was just fast and not going out of rhythm. Sinus tachycardia is the diagnoses. The past few weeks I have been getting a flutter in my throat and it caused me to start having anxiety again. Now I'm on my heart medication 2 times a day. To help slow down my heart. Is the flutter sensation I'm having in my throat normal or should I make appointment with my primary dr? I notice it get worse of the evening after I have ate or When I'm anxious. Sometimes it just happens and makes me have an anxiety attack.
