<s>[INST] For the last 9 days I have been experiencing a "spacey" feeling, sometimes bad enough that I have to lay down, in conjunction with me heart. My heart beats fine, normal, a bit weak ( it feels) then it feels like it stops for 2 seconds. When it stops I feel sort of pressure like I have to burp in my throat and it makes me gasp along with a fluttery feeling in my chest. I am a  28 year old female [/INST] Hello! Welcome and thank you for asking on Chat Doctor! Your symptoms could be related to low blood pressure or panic attacks. Orthostatic hypotension can not be excluded either. For this reason, I would recommend you to closely monitor your blood pressure values and refer them to your doctor. It is also necessary consulting with your doctor and performing some tests: - a resting ECG-complete blood count for anemia-blood electrolytes- a Head Up Tilt test for orthostatic hypotension- an ambulatory 24-48 hours ECG monitoring to investigate for possible cardiac arrhythmia-thyroid hormone levels for thyroid dysfunction. Hope you will find this answer helpful! Wishing good health,  </s>
