Irregular heartbeat care in Portsmouth

Electrophysiology is the cardiac specialty of the heart's electrical system. Portsmouth Regional Hospital's electrophysiologists diagnose and treat abnormal heart rhythms (arrhythmias), which can occur when the heartbeat is too fast, too slow or irregular.

When your heart's electrical system doesn't function properly, it could increase your risk for other heart problems.

Electrophysiology (EP) studies

When an electrocardiogram (EKG) is not able to provide a complete diagnosis for a person with an abnormal heart rhythm, an EP study may be needed. During this procedure, EKG signals are recorded as narrow catheters are inserted through the veins into the heart. The electrophysiologist may stimulate the heart to trigger an abnormal rhythm and record the signals to assist in diagnosing and treating the abnormality.

Symptoms of cardiac arrhythmia

Arrhythmias may cause a variety of symptoms, including:

  • Chest palpitations
  • Lack of energy
  • Dizziness
  • Chest discomfort
  • Shortness of breath
  • Fainting spells

Even if your symptoms are mild, discuss them with your cardiologist. Untreated, arrhythmias greatly increase the risk of having a cerebrovascular accident (stroke) or developing heart disease.

Heart arrhythmia treatment

In addition to ongoing investments in new technology, Portsmouth Regional Hospital collaborates with the area’s leading heart doctors to offer advanced EP services to people throughout the Seacoast Region.

The board-certified electrophysiologists at our hospital’s Heart & Vascular Institute have decades of experience and training in the latest diagnostic and treatment approaches.

We take a variety of approaches to diagnose and treat heart arrhythmias, choosing the least invasive options first. Medications may be effective in slowing rapid heart rates, and cardioversion may be used to restore normal heart rhythm with an electric shock if medications aren’t effective.

Other heart arrhythmia treatments performed at Portsmouth Regional Hospital include:

  • Radiofrequency ablation
  • Pacemaker implantation
  • Implantable cardioverter defibrillator implantation
  • Cryoablation

Cryoablation

Cryoablation is a procedure that uses extremely cold temperatures to destroy damaged tissue. For heart arrhythmias, cryoablation is performed in an attempt to disable heart cells that create an irregular heartbeat. Although most cryoablation procedures are performed by putting a needle through the skin and targeting the desired area, cryoablation can also be performed as open surgery.
