Disturbances In Your Heart: Ventricular Tachycardia

While most serious issues related to heart rhythm disturbances occur in the heart’s upper chambers, or atria, sometimes they do occur in the lower chambers, the ventricles, which are the main pumping chambers. This can cause a very rapid heartbeat called ventricular tachycardia. It’s usually caused by scarring from a heart attack or other issues … Read More

The most common ones that we hear about are atrial fibrillation and its cousin, atrial flutter. When this occurs, the heart’s electrical system misfires, causing the rapid firing of too many different impulses … Read More

Do You Have a Slow or Racing Heartbeat?

During our lives, we have a one in three chance of developing a heart rhythm abnormality. In cardiology, the field of electrophysiology focuses on heart rhythm disturbances—or heart arrhythmias as they are called.
