Abnormal Heart Rhythm

What are abnormal heart rhythms?

Heart & Rhythm treats patients with abnormal heart rhythms. An abnormal heartbeat is known as arrhythmia and can have many causes and symptoms, some of which are completely normal. Causes range from a normal, healthy heart to coronary heart disease. The treatments we offer may include medication, implanted devices, medical procedures, and monitoring.

Typical causes:

  • Coronary artery disease
  • Electrolyte imbalances in your blood
  • Changes in your heart muscle
  • Injury from a heart attack
  • Healing process after heart surgery
  • Irregular heart rhythms can also occur in “normal, healthy” hearts

 

Symptoms of an abnormal heart rhythm:

  • Palpitations (thumping or fluttering in your chest)
  • Racing heartbeat (tachycardia)
  • Slow heartbeat (bradycardia)
  • Chest pain
  • Shortness or loss of breath
  • Lightheadedness or dizziness
  • Sweating
  • Fainting (syncope) or near fainting
  • Palpitations (a thumping or fluttering sensation in your chest)
  • Feeling tired

 

Treatments performed at Heart and Rhythm:

  • Medications, from supplements to anti-arrhythmic drugs
  • Medical procedure
    • Cardioversion: Cardioversion restores the heart to a normal rhythm using external electric shocks. You may recognize the term, “defibrillation’, which is cardioversion done in an emergency to prevent death from sudden cardiac arrest.
    • Radiofrequency ablation: This procedure is used to reduce pain. Pain signals are decreased in small areas of nerve tissue, which are heated up using an electrical current produced by a radio wave.
  • Devices: Implantable devices, such as the pacemaker and the implantable cardioverter defibrillator (ICD), are used to control the heart’s rhythm.
  • Supportive care: Heart rhythms can be monitored using an electronic device.

 

There are four primary types of arrhythmia:

  • Premature (Extra) Beats: These are extra, abnormal heartbeats and begin in one of the heart’s two lower chambers.
  • Supraventricular Arrhythmias is caused by the disruption of normal electrical pulses in the heart which results in rapid heartbeat.
  • Ventricular Arrhythmias, a condition in which the lower chambers of the heart (ventricles) beat very quickly.
  • Bradyarrhythmias: This is due the cardiac conduction system having a dysfunction, causing the heart to have a ventricular rate of less than 60 beats per minute (bpm).
