I havent done any thing to my heart rate up. What is this Im feeling?
Thanks for your question on Chat Doctor. In my opinion, we should first rule out arrhythmia in your case. Arrhythmia is rhythm disturbances in heart. It can cause palpitations, chest pressure, tightness etc. It also causes decrease blood supply to brain. And this causes fainting episodes. So better to consult cardiologist and get done 1. Blood pressure monitoring 2. ECG 3. 2d echo. 4. Holder monitoring (24 hours continuous monitoring of ECG). You may need anti arrhythmia Chat Doctor.  Don't worry, you will be alright. First diagnose yourself and then start appropriate treatment. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
