Conversation: The conversation between human and AI assistant.
[|Human|] I am a healthy 42 year old woman. I run every day. I recently experienced uncomfortable episodes that sent me to the ER. With no diagnosis. My heart kidneys and electrolyts and thyroid are fine, yet I go into shaking fits where my heart rate rises over 145. It is very uncomfortable and frightening and I cant seem to control it. The first onset symptom is tightening of musclses and hands cramping closed. I have no control of it.
[|AI|]  Hi, First, you should do an ECG and an ECHO on your heart, if they were normal you should do an ECG with effort, besides measuring blood pressure. If you take oral contraceptive pills or a hormonal replacement therapy, you should ask a gynecologist to adjust the dose. If you did not have a cardiac lesion, take the pills, Chat Doctor.  Hope I have answered your query. Let me know if I can assist you further.
