Seizures
A seizure is an uncontrolled, sudden electrical disturbance in your brain. When you have long QT syndrome, your heart would beat erratically in abnormal patterns. As a result, the brain would eventually do not get sufficient oxygen to operate, which might trigger seizures. In some cases, this condition would cause some changes in your feelings, consciousness, movements, or behavior. When you experience recurrent seizures, then you might be at risks of epilepsy. This is often considered a serious symptom that can lead to many further complications. Thus, make sure to seek immediate medical attention. [2]
