Heart Rhythm Disorders Q & A

What are heart rhythm disorders?

Heart rhythm disorders or arrhythmias are conditions that cause an irregular heartbeat. A heartbeat results from an electrical pulse that spreads through all the cells of your heart muscle. When you have an irregular rhythm, there is an interruption in the electric signal in the heart.

The heart's electrical system coordinates movement between the atria and ventricles — the top and bottom chambers of the heart. The right side of the heart receives blood from the body and delivers it to the lungs to collect oxygen, and the other receives blood from the lungs and distributes it to the rest of the body. 

An arrhythmia affects the rate or rhythm of the electric pulse, causing it to be too fast, too slow, or irregular. Heart rhythm disorders impact blood flow through the heart, which could cause life-threatening symptoms or no symptoms at all. 

What are the symptoms of a heart rhythm disorder?

If you have an arrhythmia, you may notice a slow or fast heartbeat or a brief, irregular feeling in your chest. You may also have other symptoms, such as: 

  • Chest pain or discomfort
  • Shortness of breath
  • Dizziness or lightheadedness
  • Sweating or blurry vision 
  • Fatigue or general malaise 

Many people have heart rhythm disorders that go undiagnosed until routine physicals, as part of a preventive cardiology workup, or a cardiac event. 

What are some heart rhythm disorders?

The most common heart rhythm disorder is atrial fibrillation (AFib), when the upper chambers of the heart pulse quickly and irregularly. 

Other heart rhythm disorders include: 

  • Ventricular fibrillation (V-fib)
  • Premature atrial or ventricular contractions (PAC or PVC)
  • Sinus tachycardia, fast heartbeat
  • Sinus bradycardia, slow heartbeat
  • Atrial flutter, irregular movement in the atria
  • Supraventricular tachycardia (SVT)
  • Heart block

The Heart One Associates team may recommend an at-home EKG monitor, electrocardiography (EKG/ECG), or electrophysiology studies to diagnose your heart rhythm disorder. 

What are the treatments for heart rhythm disorders? 

The Heart One Associates team develops a personalized plan of care based on advanced testing and diagnostics, including nuclear stress tests, cardiac viability studies, transesophageal echocardiogram (TEE), echocardiogram, a multi-acquisition gated scan (MUGA), or an implantable loop recorder. 

Depending on how your arrhythmia affects circulation, your treatment plan may include: 

  • Medication
  • Ablation 
  • Cardioversion
  • Pacemaker and multi-point pacing
  • Biventricular implantable cardiac defibrillator (BIVICD)
  • Automatic implantable cardioverter defibrillator (AICD)
  • LifeVest ® wearable cardioverter defibrillator (WCD)

They also offer ongoing heart rhythm support and device management, such as pacemaker interrogations, implantable cardiac defibrillator (ICD) interrogations, pacemaker lead extraction, and remote monitoring.
