How do you treat bundle branch block?
If you have bundle branch block with low heart-pumping function, you may need cardiac resynchronization therapy (biventricular pacing). This treatment is similar to having a pacemaker implanted. But you’ll have a third wire connected to the left side of your heart so the device can keep both sides in proper rhythm.
