Cardiac Electrophysiology

At Butler Health System, we take cardiac electrophysiology to heart, providing expert and individualized treatment for all types of arrhythmias. A member of our cardiovascular care team, our resident cardiac electrophysiologist Dr. David Schwartzman specializes in the "electricity" of the heart to address abnormal heart rhythms and the cause of the irregularities. Our team of specialists use top-flight technology to diagnose and treat heart rhythm disorders—in order to help our patients live their best lives.

Diagnosis & Treatment Options

As a cardiac electrophysiologist—or heart electrician—Dr. Schwartzman works to diagnose and treat each patient with a passion and commitment to return them to a life of normalcy.

The main types of arrhythmia include:

  • Premature (extra) beats
  • Supraventricular arrhythmias, including atrial fibrillation (AFib) and supraventricular tachycardia (SVT)
  • Ventricular arrhythmias, such as ventricular fibrillation or tachycardia
  • Bradyarrhythmias (heartbeat too slow)

Arrhythmias may be treated through:

  • Ablation
    The use of heat, cold or radio waves to close off electrical pathways that are causing abnormal heart rhythms
  • Devices
    The implant of cardiac devices to manage abnormal heart rhythms
  • Medications
    The use of medicine to manage abnormal heart rhythms

    What is atrial fibrillation?

    Atrial fibrillation is a disorganized and irregular heart beat originating in the top chambers of the heart.

    What is an ablation procedure?

    An ablation is a minimally invasive way to find and eradicate the cause of irregular or rapid heartbeats and stop these disruptions from occurring.

    Why did I pass out?

    Passing out, or syncope, can occur for many reasons, but the cause should always be investigated.
