would be concerned. it sounds like the doctor may be lying to you. in the situation you could have an irregular heart arrythmia that spurs these panic attacks. this could mean you are in need of a long drawn out procedure that often times requires heart surgery. hope this helps. good luck!
doctor could you help? . months ago i went to er with high anxiety and my heart racing. i was listened with stethoscope and told to be fine. i wanted ecg so they did it for a min. and reassured me. but i saw the automatic interpretation saying abnormal ecg. did they miss it or is this normal when having panic attack.
