My brother complained of stomachache and vomiting last afternoon and after sometime he started getting pain in the chest along with shivering and headache. His body was extremely cold. My parents took him to hospital where ECG, Oxygen levels, Stomach xray came normal, however, there was slight indication of Jaundice. In the night time when he slept his heartrate and pulserate dropped to 35 and after sometime when he again slept his heartbeat dropped to 35. His CT scan results are yet to come but wanted to know as to what could be reason behind all this?
