Tachycardia is an abnormally rapid heartbeat, greater than 100 beats per minute at rest.

The UPMC Heart and Vascular Institute's Cardiac Electrophysiology Program treats arrhythmias like tachycardia, and other heart disorders associated with a high risk of sudden death.

What Is Tachycardia?

A normal heart rate in adults is usually between 60 and 100 beats per minute. Doctors define tachycardia as an abnormally rapid heart rate at rest, or where the heart beats over 100 times a minute.

Tachycardia types, causes, and complications

Although some types of tachycardia are mild, ventricular tachycardia can be life-threatening and requires immediate medical attention.

Sinus tachycardia

  • Rapid firing of the sinoatrial node — the natural pacemaker of the heart — when the body needs extra oxygen
  • Occurs normally in response to:
    • Exercise
    • Excitement or fear
    • Pain
    • Fever
    • Excessive thyroid hormone secretions
    • Stimulants (such as caffeine, alcohol, cold medicines, methamphetamine, cocaine)

Paroxysmal supraventricular tachycardia (Psvt)

  • Bouts of rapid, regular heart beating that originate in the atrium (the upper chambers of the heart)
  • Typically not life-threatening
  • Causes symptoms of:
    • Palpitations
    • Chest discomfort
    • Shortness of breath
    • Dizziness
    • Fainting

Ventricular tachycardia (V-Tach)

  • Rapid heart beat originating in the ventricles
  • Less blood to be pumped through the body
  • Most often caused by other heart or vascular problems, such as:

Tachycardia Symptoms and Diagnosis

Tachycardia symptoms

If you have tachycardia, your heart can beat very fast — over 100 times a minute at rest.

Tachycardia symptoms may include:

  • Dizziness
  • Light-headedness
  • Fluttering in the chest
  • Fainting

Diagnosing tachycardia

During your physical exam, your doctor at the UPMC Heart and Vascular Institute's Cardiac Electrophysiology Program will:

  • Ask about your symptoms and when they started.
  • Discuss your medical history.
  • Listen to your heart with a stethoscope.

To confirm a diagnosis of tachycardia, your doctor may order additional tests and procedures such as:

  • An electrocardiogram (EKG)
  • An echocardiogram
  • A Holter monitor
  • An exercise stress test
  • A tilt table test
  • Invasive electrophysiology tests
  • Blood tests

Tachycardia test results

Your doctor or nurse will tell you when to expect your test results and will call you when they're available.

Tachycardia Treatment

Rapid heart rates can originate from either the atria or the ventricles of the heart. The treatment for your tachycardia may vary between medication or surgery depending on the severity of your condition. Rhythms from the ventricle are more often considered life-threatening.

Treatment goals

At the UPMC Heart and Vascular Institute's Cardiac Electrophysiology Program, the goals of tachycardia treatment are to:

  • Minimize stroke risk
  • Control heart rate
  • Restore normal heart rhythm

Your doctor may prescribe medications and order certain procedures to meet these treatment goals.

Medicines for treating tachycardia

Medicines used to slow the heart rate:

  • Digitalis or Digoxin
  • Verapamil
  • Diltiazem (Cardizem®)
  • Metoprolol (Lopressor® or Toprol-XL®)
  • Atenolol

Medicines used to maintain a regular heart rhythm:

  • Sotalol (Betapace AF®)
  • Propafenone (Rhythmol®)
  • Amiodarone (Pacerone® or Cordarone®)

Medicines used to prevent clot formation and help reduce the risk of stroke:

  • Blood thinners such as:
    • Warfarin (Coumadin®)
    • Aspirin
