[|Human|] Hey, my friend is dying and I just would like to knowwhats wrong with him. He hs to take medicine, because his hart rate is too fast and if he stps he could have a heart attack, yet the medicine maes him throw up blood and he constantly has a nose bleed. Either way its killing him.
[|AI|]  Hello, Tachycardia (Increased heart rate) can have many reasons, and it could be idiopathic too (Means no cause is there). The most common among them is an infection (Septicemia), cardiogenic shock, Ischemic heart disease. Overall it is the emergency and true underlying cause can be found out there, if this is the bleeding symptoms then it could be valvular heart disease. Hope I have answered your query. Let me know if I can assist you further.
