A member asked:
What conditions, in general, might cause the qtc interval on an ecg to become prolonged as the heart rate increases?
A doctor has provided 1 answer
causes of prolonged QT interval are genetic, drugs (of which there are many)low potassium, low calcium and heart failure . These causes result in the disturbance of the conduction system in the heart
