Cardiac Arrhythmia

About Arrhythmias

Arrhythmias are disturbances of the regular heart rhythm. Heartbeats may be:

  • Too fast (tachycardia – more than 100 beats/minute)
  • Too slow (bradycardia - less than 60 beats/minute)
  • Irregular heartbeat – skipped or extra beats

Arrhythmias can occur in a healthy heart and be of little significance or they may point to an underlying heart problem. Types of arrhythmias are:

  • Atrial fibrillation - heartbeat irregular and too fast
  • Paroxysmal atria tachycardia – heartbeat regular but too fast
  • Ectopic – extra heartbeats
  • Ventricular tachycardia – heartbeat very fast and regular. If it lasts more than a few seconds it can be dangerous.
  • Ventricular fibrillation – heartbeat very fast and uneven; heart just quivers, causing cardiac arrest. This is a medical emergency: call 911.
Symptoms & Diagnosis

Symptoms may include:

If arrhythmias occur often or if episodes are prolonged, some or all of the following tests may be performed:

  • Physical exam and medical history
  • EKG
  • Holter monitor/Event monitor
  • Electrophysiologic studies (EPS)
  • Transesophageal echocardiography (TEE)
  • Tilt table test
  • Cardiac catheterization
  • Coronary angiography
  • Blood tests
Treatment Options for Arrhythmias

Treatment will depend on the type and severity of the arrhythmia. If it is mild no treatment may be needed. If treatment is necessary, it may include:

  • Medications – anti-arrhythmics, blood thinners
  • Medical procedures:
    • Pacemakers
    • Implantable cardioverter defibrillator (ICD)
    • Tissue ablation using laser, cryotherapy or radiofrequency
    • Vagal maneuvers – as supervised by your doctor
