Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, your fast heart rate is mostly due to stress and anxiety. You must have attempted suicide by taking overdose of muscle relaxant Chat Doctor.  This means you are going through a lot of stress, anxiety and depression. All these can cause fast heart beats. So better to consult psychiatrist and get done counselling sessions. Try to identify stressor in your life and start working on its solution. You may need anxiolytic and antidepressants
