Specialties

Dr. James J Ong has the following 3 specialties

  • 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.

  • 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.

Great Doctor, great office staff.

Dr. Ong is extremely busy but takes his time with his patients. His staff (Christina and Jenni) run the office so efficiently that wait time is surprisingly short for such a busy office.
