Mark Kiessling

I specialize in treating heart problems that are caused by the heart’s electrical system. I have always been interested in bringing order out of chaos and the electrical system is sometimes subject to the development of chaotic rhythms.

Some cardiac electrical problems are dramatic. Providing treatment in those cases can be lifesaving. Many cardiac electrical problems impair a patient’s lifestyle. In those cases, effective treatment can mean a much-improved quality of life.

My goal is to use my education, training and experience to determine the most effective treatment for my patients. Working with patients to improve their quality of life so they can get back to doing more of the things that make their lives fulfilling is always rewarding.
