[|Human|] Hello. My friend last night experienced two episodes of sudden bloodrush to the head, felt very warm and his heart pounded like crazy. It made us both nervous. The first time I thought it could be because he had accidently inhaled fumes from massageoiles, but the second time he was just lying on the couch relaxing. It went 5-6 hours between these two episodes. What can it be? He is good health normally, 22 years old.
[|AI|]  Hi, Thank you for posting your query. Based on the symptoms, we should exclude a diagnosis of cardiac arrhythmia (abnormal heart rate or rhythm). This can be done by tests such as ECG and Holder monitoring. Please consult a cardiac electrophysiologist or a cardiologist for evaluation. As of now, there is no need to worry. Please get back if you require any additional information. Best wishes, Chat Doctor. Ly/
