If a person has brugada syndrome, will that always appear on a ekg?

ECG for Dx: Brugada syndrome is a potentially life-threatening heart rhythm disorder which is sometimes inherited. A Brugada pattern generally shows up on ECG. Your doctor may also give you medication which helps the Brugada pattern "show up" on the ECG. I suggest you see a cardiologist to be properly evaluated for this condition. I wish you well with your health!
