Arrhythmia

A rhythm disorder, or arrhythmia, is an abnormality in the regular beat of the heart. The heart may beat either too fast (tachycardia), too slowly (bradycardia) or beat irregularly. Arrhythmias occur when there is a disturbance in the way the heart transmits electrical impulses or as a result of a heart attack. Either the natural pacemaker develops an abnormal rate or rhythm, the normal pathway for a heartbeat is interrupted, or another part of the heart takes over as the pacemaker.

Arrhythmia Diagnostic Services

After you have described your symptoms and your physician has performed a physical examination, any one of several diagnostic tests may be used to diagnose and determine the severity of the coronary artery disease and your current heart health. These diagnostic procedures may include an electrocardiogram, Holter monitoring or an electrophysiology study.

Arrhythmia Treatment

Some arrhythmias are treated successfully with medications that will regulate the heart rate. Mission Hospital heart experts may also recommend a procedure called radiofrequency ablation, which uses radio waves to destroy the abnormal pathways in the heart that are causing rhythm problems.

The Mission Hospital Cardiac Catheterization Lab offers comprehensive medical treatment, including radio frequency ablation.

Pacemakers

Pacemakers and implantable cardioverter defibrillators (ICDs) are devices that are implanted under the skin and attached to the heart muscle with electrodes to regulate the heart's rhythm.

At Mission Hospital Heart Center, electrophysiology studies are conducted in a dedicated electrophysiology lab by highly skilled electrophysiologists. The cardiac catheterization lab is equipped with the most advanced technology to ensure more accurate diagnoses.
