Atrioventricular (AV) nodal reentrant tachycardia (AVNRT) is an irregular heart rhythm that can cause excessively fast heart rates. Though not usually serious, early diagnosis can help prevent severe ...

Having an accelerated junctional rhythm occurs when the atrioventricular node in your heart beats too quickly. It happens as a result of damage to your heart’s primary natural pacemaker. There’s no ...

When high doses of AV blocking drugs are not successful to lower ventricular rates in the setting of atrial fibrillation, AV node ablation can be utilized. Remember that all atrial action potentials ...

Your heart's job is to keep your pulse steady to pump blood throughout your body. Sometimes your heart rate is slower when you're relaxing, and sometimes it's faster when you're exercising or stressed ...

What Is the Heart Conduction System? The heart conduction system is made up of cells, nodes, and signals that help your heart to beat. In fact, the cardiac conduction system is responsible for our ...

Atrioventricular reentrant tachycardia (AVRT) is a rhythm problem in your heart that makes it beat too fast. It results from an extra connection between your upper and lower chambers. You might hear ...

In order for the heart to do its work of pumping oxygen-rich blood to the body, it needs a trigger or electrical impulse to generate a heartbeat. This electrical impulse originates from the sinus node ...

Supraventricular tachycardia (SVT) is a heart rhythm disorder that originates in the heart’s upper chambers, called the atria. The primary symptom of SVT is a rapid heartbeat. There are several types ...
