Diagnosis of Arrhythmia

Not everyone is affected the same way by irregular heart rhythms. You may be exhausted and unable to walk up a flight of stairs, you may notice a flutter or strange sensation in your chest, or some people experience almost no symptoms at all. Don’t ignore your symptoms — getting quick treatment for your arrhythmia can help you avoid more difficult treatment, heart damage, heart attack and even stroke.

The most common signs and symptoms of arrhythmias include:

  • A feeling that your heart is skipping a beat
  • A feeling your heart is “fluttering”
  • A heartbeat that is too fast or too slow
  • Pauses between heartbeats

More serious symptoms include:

  • Anxiety
  • Chest pain
  • Dizziness
  • Fainting or near-fainting
  • Severe heart palpitations
  • Shortness of breath
  • Sweating

At the Electrophysiology and Arrhythmia Center at the Orlando Health Heart & Vascular Institute, our experts have decades of experience in electrophysiology (assessing your heart’s electrical system). Whether you have atrial fibrillation (AFib) or premature ventricular contractions (early heartbeats), a precise diagnosis will allow us to create the most personalized treatment plan for you so you can get back to enjoying life again.

We offer the following diagnostic tests:

  • Cardiac testing
  • Event monitoring
  • Holter monitor
  • Implantable cardiac rhythm monitor
  • Stress testing
  • Tilt table testing
  • Transthoracic (TTE) and transesophageal echocardiogram (TEE) 

Arrhythmia Conditions We Treat

Whether your arrhythmia is fairly common or is complex and difficult to diagnose, we work together to make sure you get the best possible care for your condition. Our experts have experience treating the following arrhythmias:

  • Tachycardia. A fast heart rhythm with a rate of more than 100 beats per minute.
  • Bradycardia. A slow heart rhythm with a rate below 60 beats per minute.
  • Supraventricular arrhythmias. Irregular heartbeats that begin in the upper chambers of the heart, including:
    • Bypass tract tachycardia
    • Atrial fibrillation (AFib)
    • Atrial flutter
    • AV node re-entrant tachycardia (AVNRAT)
    • Atrial tachycardia
    • Inappropriate sinus tachycardia (IST)
    • Paroxysmal supraventricular tachycardia (PSVT)
    • Premature atrial contractions (PACs)
  • Ventricular arrhythmias. Irregular heartbeats that begin in the lower chambers of the heart, including:
    • Premature ventricular contractions (PVCs)
    • Ventricular tachycardia (V-tach)
    • Ventricular fibrillation (V-fib)
  • Bradyarrhythmias. Slow heart rhythms that may be caused by disease in the heart’s conduction system, including:
    • Atrioventricular (AV) node
    • Sinoatrial (SA) node
    • HIS-Purkinje network
