### input:
Hi I am a 22 yr old female, with family history of heart problems and epilepsy . Two days ago whilst drinking a fizzy drink I had chest pains and passed out for a few minutes, my mum said that I had turned blue and stopped breathing. After I had come round we went to A&E where I was given an ECG which showed an abnormality, the doctors didn t really explain and just sent me home. My mum wasn t happy with me just being at home with no explanation so we went to our local GP who did another ECG, this time the machine showed abnormal repolarization and possible ischaemia. I don t really know what all of this means and I am really worried now! I had looked on the internet the night before GP appt and had really convinced myself that I had suffered from Swallow Syncope as my symptoms exactly matched. Now I don t know what to think so some advice would be greatly appreciated.

Hi, I see you've already suffer with a heart disease and epilepsy, it would have been better if you had specified what kind of heart disease you suffer with. In the background of both the clinical history, the episode is more likely to be a syncope/arrhythmia. If there was any history of tongue bite or urine incontinence, a seizure also needs to be considered. It was good that an ECG was documented during the event. Examining the ECG as a whole can give us clue if you've had a serious problem. In other terms, the machine interpretation of early repolarization has no much significance as they are subjected to many biases.  I would instead suggest you to discuss with your doctor/submit the ECG to an online medical advising site such as yours for better interpretation of the ECG and whether those can explain the symptoms you had recently. Hope this answers your query. Regards
