In brief: Arrythmia
The different waves on the ekg represent the electrical impulses reaching different parts of the heart as it beats.
Long qt syndrome is a condition where the electrical signals take longer than normal to pass through the heart. It may be caused by medication or may be congenital. Long qt may progress to life-threatening arrhythmias, so it is important to be monitored by your doctor frequently.

In brief: See below
T-waves and qt intervals are among the measurements performed on ECG tracings that provide a window into the health of the muscle and the electrical system of the heart.
Long qt is a potentially severe abnormality in the way the heart's electrical system resets itself after a heart beat. Some cardiac and electrical abnormalities can be unmasked at faster heart rates and thefore the stress test.
