Arrhythmia treatments in Virginia

For more than a decade, HCA Virginia's physicians and hospital teams have worked tirelessly to build the region’s premier cardiac care centers. We take care of your valves, veins and arteries to ensure your heart health. As part of that care, our electrophysiologists diagnose and treat arrhythmias (abnormal heart rhythms), using advanced technology to resolve your irregular heartbeat.

Types of cardiac arrhythmias

Electrical signals to the heart coordinate your heartbeats. When your heart's electrical system does not function properly, your heart rhythm becomes too fast (tachycardia), too slow (bradycardia) or irregular. This can lead to dizziness, fatigue, shortness of breath and even a heart attack or cerebrovascular accident (stroke). It may also signal underlying heart disease.

Types of arrhythmias include:

  • Atrial fibrillation (AFib)
  • Atrial flutter
  • Premature atrial contractions
  • Premature ventricular complex (PVC)
  • Supraventricular arrhythmias
  • Supraventricular tachycardia (SVT) or paroxysmal SVT
  • Sick sinus syndrome
  • Ventricular tachycardia
  • Ventricular fibrillation


AFib is the most common heart arrhythmia. It may be caused by environmental, behavioral or genetic factors. It is often found in patients with atherosclerosis, angina (chest pain), hypertension and lung problems.

AFib is also commonly associated with conditions such as heart failure. If left untreated, it can become permanent over time, increasing your odds of more serious, life-threatening issues. This is, in part, because AFib can cause blood to pool and form clots in the heart's left atrial appendage, significantly increasing the risk of having a stroke. As a result, patients experiencing this heart condition may need to take warfarin (blood thinning medication) long-term.

Stroke risk assessment

Symptoms of AFib

Patients with AFib typically experience symptoms, including:

  • Difficulty exercising
  • Dizziness, lightheadedness or fainting
  • Fatigue or weakness
  • Irregular or rapid pulse or heart beat
  • Pain or pressure in the chest
  • Palpitations or a pounding feeling in the chest
  • Racing feeling in the chest
  • Shortness of breath
  • Sweating

Diagnosing heart arrhythmias

Electrophysiology (EP) is the cardiac specialty that studies the heart's electrical system. The skilled electrophysiologists in our EP labs conduct imaging exams and diagnostic tests to determine the source of the arrhythmia. They can then determine the right approach and procedures to help steady the rhythm of your heartbeat.

Treatments for heart rhythm disorders

Depending on the type of irregular heartbeat you have, our cardiac specialists may suggest:

  • Implantable cardioverter defibrillator (ICD) implantation
  • Pacemaker implantation
  • Radiofrequency ablation

Convergent (or hybrid) maze

The maze procedure is named after the maze-like set of incisions made on the left and right atria. It is a minimally invasive endoscopic procedure that creates scar lines (lesions) on the epicardium (the outside of the heart). However, it does not compromise the pericardium (the membrane sac enclosing the heart and other major surrounding vessels). The lesions work to divert the abnormal electrical impulses in the heart, isolating them and allowing the heart to return to its normal beating pattern.

Treatments for AFib

In addition to helping you find the right combination of medication and lifestyle changes, our hospitals offer innovative treatments for AFib, such as:

  • Cardiac ablation
  • Cardioversion
  • Implantable defibrillators
  • Pacemakers

Left atrial appendage closure (LAAC) for non-valvular AFib

The LAAC implant is a treatment alternative for non-valvular AFib. It closes off the left atrial appendage (believed to be the primary source of stroke-causing clots in patients with this condition). This keeps harmful blood clots from entering the bloodstream. For this reason, LAAC may enable you to discontinue warfarin and considerably reduce your AFib-related stroke risk.
