25yo female. healthy, fit, no chronic conditions. 57 126lbs. Resting HR has always been high at 80bpm, BP between 110-115 systolic. have had 4-6 incidences over last 3 years of palpitations, lightheadedness (not dizzy), hand tremors, general weakness, sweats and hot flashes lasting 3-15mins. Im not diabetic but when my blood sugar runs low the symptoms come on slower so thats not it. I also used to get this sharp chest pain that would hurt more then pop away with deep inspiration. this is accompanied by the sweats and palpitations as well. my doctor said it was a knot in my intercoastals... any thoughts? i got scared i was going to pass out yesterday during one of these spells
Thanks for your question on Chat Doctor. I can understand your concern. By your history and description, possibility of stress and anxiety related symptoms is more. But since you are having palpitations, sweating, dizziness etc., we should first rule out heart diseases like arrhythmia. So get done ECG, 2d echo and Holder monitoring (24 hours continuous recording of ECG). If all these are normal then no need to worry about arrhythmia or other heart diseases. Sometimes uncontrolled stress and tension can cause similar kind of symptoms. So consult psychiatrist and get done counselling sessions. Try to identify stressor in your life and start working on its solution. You may need anxiolytic Chat Doctor.  Don't worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
