When supraventricular tachycardia occurs in someone with significant
coronary artery disease, the heart may not receive enough blood to keep up with
the demands of the increased heart rate. If this occurs, the heart may not get
enough oxygen (ischemia), potentially causing a heart attack (myocardial
Supraventricular tachycardia may result in heart failure, especially
in people with diseases of the heart valves (particularly aortic stenosis or
mitral stenosis) or with a weakened heart muscle (cardiomyopathy).
And if supraventricular tachycardia persists for a long period of
time, it may cause a normal heart to weaken and heart failure to develop (known
as a tachycardia-mediated cardiomyopathy), although it is often reversible if
the supraventricular tachycardia is corrected.
It's the news you don't want to hear from your cardiologist: One or more of your coronary arteries -- the blood vessels that supply blood to your heart -- is blocked. You have coronary artery disease, the No. 1 killer of U.S. adults.
So does this mean you're headed for bypass surgery? Maybe not, if your situation isn't an emergency.
You might have other options -- including less drastic procedures to reopen those arteries, medication alone, or even radical lifestyle change.
What's your best option?...
