There are a variety of reasons that the heart can become structurally abnormal, such as if you've had a heart attack in the past, if you have some sort of genetic abnormality that you might have inherited from your mother or your father. Now, in some patients, however, they can have an abnormal heart for other reasons. In rare cases, if the heart is structurally normal, this can actually result in a dangerous rhythm, though again that's relatively rare if there's not some other underlying heart disease that might be contributing. These can appear as occasional extra beats that one might experience as skipped beats, or as a rapid array of beats that are occurring all in a row, termed ventricular tachycardia. What we mean by this is that there are some patients out there who really have no other underlying heart disease except some abnormality in their electrical system of the bottom chambers of their heart, or the ventricles, that can cause the heart to go out of rhythm.
Ventricular arrhythmias can occur in both structurally normal and structurally abnormal hearts. But I'm going to try and clarify things for you a little bit, both about what this might be and how we might go about treating it. Now, if you go on the internet and you look up ventricular tachycardia, you might find yourself concerned because people tell you, oh, this is associated with sudden death, or, oh, you might have to seek urgent medical attention. Today, I'm going to talk about the condition known as ventricular tachycardia. Suraj Kapa, a Mayo Clinic cardiologist specializing in heart rhythm disorders.
