If you have a heart rhythm disorder, you need a team with expertise to get your heart beating as it should. Our Electrophysiology Program offers specialized diagnosis and up-to-date treatments for common and complex arrhythmias. Our skilled team coordinates your care, so you can focus on recovery and getting back to the activities you enjoy.

Conditions we treat

At Dignity Health, our electrophysiologists treat all types of conditions affecting the heart’s electrical system. We have experience in arrhythmias caused by underlying heart conditions such as coronary artery disease, valvular heart disease, adult congenital heart disease and cardiomyopathy.
