Catheter ablationĪ surgical procedure called catheter ablation is sometimes used to destroy the extra electrical pathway. Some anti-arrhythmic drugs that may be prescribed include beta-blockers, calcium channel blockers, flecainide, or propafenone. Medications may be used to treat abnormal heart rhythms. There are a variety of ways to treat heart arrhythmia caused by circular electrical activity, depending on the severity of the symptoms an individual is experiencing. This is similar to AVNRT, but the pathway connecting the atria and ventricles is not in the AV node.Īs it happens, WPW - which is a possible cause of heart arrhythmia due to circular electrical activity - is a specific type of AVRT. For example, AVNRT refers to a reentry circuit within or next to the AV node.Īnother possible cause is AV reentrant tachycardia (AVRT). There are several different ways extra electrical pathways can form and an individual may be diagnosed with a specific medical condition depending on how and why the electrical activity is trapped in a circular pattern. It can create a shortcut for the electrical impulses causing the heart to beat too quickly or at the wrong time. In some hearts, an extra electrical pathway can interfere with this normal pattern. Ventricular contraction is what causes blood to be pumped out of the heart. This is where the contraction starts.Īnother node called the atrioventricular (AV) node sends the impulse to the lower heart chambers called the ventricles. From there, the impulses travel to the atria, or upper heart chambers. In a typical heart, electrical impulses begin in the sinus node in the upper right section of the heart muscle.
