A T-wave is a component of an ECG test. It signifies the repolarization of the heart ventricles after a contraction. In the adjacent image, the T-wave is the hump on the right. Every time your heart beats, the muscle is depolarized by an electrical current that originates in the sinoatrial node of the heart.
The term long QT refers to an abnormal pattern seen on an EKG (electrocardiogram). An EKG is a test that detects and records the heart's electrical activity. With each heartbeat, an electrical signal spreads from the top of your heart to the bottom.
