Your heart requires precise electrical impulses to function and pump blood throughout your body. If you have a condition that affects the electrical activity of your heart, HCA Midwest Health offers the most current electrophysiology treatment options. The electrophysiology treatments we offer are described below.

In a cardioversion, your doctor corrects a abnormally fast heart rate—known as tachycardia —or cardiac arrhythmia to a normal heart rate using electricity or drug therapy. This procedure may be done either as a scheduled procedure or during an emergency situation.

Loop Monitor

A loop monitor is a type of cardiac monitor that is implanted just under the skin of the chest to record the electrical activity of the heart. The monitor itself is about the size of a pack of gum or a USB memory stick. The data that the loop monitor captures may tell your cardiologist:

  • Whether your medications are working
  • Whether your pacemaker or implantable cardioverter defibrillator (ICD) is working
  • Why you are experiencing chest pain, dizziness, the feeling your heart is racing or skipping a beat or other cardiac symptoms
  • Whether your heart is getting sufficient oxygen to function properly


A cardiac implant is a device that is implanted in your body in order to record the activity of your heart or to help correct conditions related to the heart. The types of implants we offer include:

  • A temporary pacemaker is a device that you may need for a period of time after you have been hospitalized for a cardiac condition or have had a cardiac procedure. The pacemaker is implanted in the chest, has tiny wires attached to the heart and its electrical pulses help keep the heart beating normally.
  • If you have a long-term heart condition, your doctor may determine that you need a permanent pacemaker. This device is implanted in the chest, has tiny wires attached to the heart and its electrical pulses help keep the heart beating normally.
  • A biventricular pacemaker—also known as cardiac resynchronization therapy (CRT)—treats arrhythmia by helping to regulate the heart beat and relieve symptoms associated with having an abnormal heart beat.
  • An automated internal cardioverter defibrillator (AICD) is a battery-powered device that keeps track of your heart rate at all times. If your AICD detects an abnormal heart rhythm, the device sends an electrical current to your heart to restore a normal rhythm.


If you have an abnormal heartbeat caused by an arrhythmia, your doctor may recommend that you undergo cryoablation. In this procedure, extremely cold temperatures are used to destroy the selected heart cells that are causing the arrhythmia.

Radiofrequnecy ablation

Used to treat cardiac arrhythmia and atrial fibrillation, this procedure uses heat to destroy selected heart cells that are causing the irregular heartbeat.
