Had an EKG done and the doc says she has a high QT. Also, she has high blood pressure.
What does QT mean? What is the outcome?
On a graph showing the output of the EKG there are sharp, pointed spikes for each heartbeat. The beginning is labeled "Q", top "R", end "S" and a short line that can be elevated, depressed or level labeled "T". QT is a measurement from Q to T. An abnormal QT can be left atrial enlargement and QTc is left ventricular enlargement.
The outcome or possible diagnosis and worse scenario could be heart failure that would indicate heart muscle damage or the heart is in the compensation stage and the enlargement is compensating for the high resistance as indicated by high blood pressure...the heart is working harder and an enlargement helps the heart pumping power to meet the resistance of narrowed arteries and also smoking may interfere with the system getting oxygen rich blood from the lungs.
An echo test may be warranted to test for chamber sizes and pumping efficiency.
