Rhythm of Your Heart: Bridge Out Ahead (Video)

The importance of the heart’s ‘electrical bridge’

Sign saying Weak Bridge

The heart is part of the body’s circulatory system, and just like the electrical system in a house has circuits that keep the power running through your home, our hearts have circuits that connect everything together and keep our hearts beating. If a circuit is out in your house, the whole system can be affected — and the heart is no different.

In this white board session, Patrick J. Tchou, MD, Associate Section Head of the Section of Electrophysiology and Cardiac Pacing in the Department of Cardiovascular Medicine, explains how a type of irregular heartbeat called AV node re-entrant tachycardia can occur when there’s an issue with the electrical bridge that connects the upper and lower chambers of the heart. This can cause a normal heart rate of 50 to 70 beats per minute to surge to 120 to 250 beats — which can be a scary situation.
