Conduction disturbances:Electrical conduction disturbances may make the heartbeat too quickly (tachycardia) or too slowly (bradycardia), and either of these situations may result in an inadequate blood supply to the brain, causing dizziness or lightheadedness. ...
it does not mean that the heart fails to pump - it does mean a failure in an aspect of the heart's ability to complete an otherwise normal function. The symptoms and signs are almost identical to those seen with cardiomyopathy. Most cases of heart failure are chronic, long-term heart fai...

A-fib may come and go, or it may be a long-term condition. A-fib can cause life-threatening blood clots, stroke, or heart failure. It is important to treat and manage A-fib to help prevent these problems.What increases my risk for A-fib?
If the heart rate is closer to 150 bpm or higher, it is a condition known as supraventricular tachycardia (SVT). In SVT, the electrical system that controls heart rate becomes dysfunctional. This generally requires medical attention. Additional resources ...
