[|Human|] Yes I just had an electrical type sensation in my chest I reached for my cell phone in my pocket but it was not there or even in the room it instantly woke me up iv not felt good today my heart was beating hard at the time  and numbness was in my hands what could this be?
[|AI|]  Hello. Thank you for your question and welcome to Chat Doctor. I carefully read your query. It could easily be a simple intercostal muscle twitching, that resembles like coming from the heart. It tends to happen after exercise and/or any physical activity that includes heavy breathing and/or after episodes of Chat Doctor.  However, I would recommend you to do an EKG, and depending on that and your sensation, a 24-hour rhythm monitor, to exclude any possible bout of any kind of arrhythmia. Also, your blood calcium levels should be measured. As for the other part, heart beats very hard in stressful situations, both psychological and physiological. My opinion is that this came as a very worrisome phenomenon to you, and the stress and anxiety from it happening again, produced the other symptoms. Please, run the tests I recommended above and discuss the results further with a general practitioner. I hope I was helpful. Take care. Kind regards,
