Rhythm of Your Heart: Bridge Out Ahead

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, cardiologist Patrick J. Tchou, MD, 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.
