Dr. Karl P Undesser has the following 3 specialties

  • Internal Medicine

    An internist is a physician who focuses on the diagnosis and treatment of conditions that affect the adult population—both acute and chronic.
    These doctors are often who adults see as their primary physicians because they treat a broad range of illnesses that do not require surgical or specialist interventions. They also work to help a patient maintain optimal health in order to prevent the onset of disease.
    In addition to treating the common cold and flu, internists also treat chronic diseases like diabetes and heart disease.

  • Cardiovascular Disease
  • Clinical Cardiac Electrophysiology

    While cardiologists diagnose and treat all types of heart disease, electrophysiologists have extended education in rhythmic disorders, also known as cardiac arrhythmia or an irregular heartbeat. An electrophysiologist typically works closely with a cardiologist and together they can treat arrhythmia, help you prevent blood clots, or restore and control a normal heart rate.
    They can also provide information on medications and devices — such as a pacemaker or an implantable defibrillator — used to control an abnormal heart rate. When it come to treating arrhythmias, there are both invasive and non-invasive treatment options and an electrophysiologist can help you decide which is right for you.

A God Send

A coworker recommended him to me. I was at wits end after a little over a year of cardiologists, tests, meds, etc. to no avail and only worsening while they kept telling me they couldn't really find anything wrong and that it was probably just anxiety or panic attacks. He knew within less than half an hour of detailed history taking exactly what the problem was, had the necessary tests done within an hour, and I was scheduled for procedure to be done in the cath lab three days later. I've been totally symptom free for almost a decade now since the procedure.
