Insertable Cardiac Monitors

Diagnosing an Irregular Heartbeat

An irregular heartbeat may be highly treatable when properly diagnosed. With an Insertable Cardiac Monitor (ICM), sometimes called a loop recorder, your doctor can learn what treatment will get you on your way to feeling better. 

Common Conditions Related to Irregular Heartbeat

Atrial Fibrillation (AFib)

With AFib, the heart’s upper chambers beat irregularly. This can increase your risk of stroke. Symptoms may include having a hard time being active without feeling tired or winded.

Unexplained Fainting

Fainting, also known as syncope, is another heart-related condition. Symptoms include feeling dizzy, changes in vision, feeling sick (nausea) or having a hard time standing.

Understanding Your Symptoms

If your doctor suspects you may have a cardiac arrhythmia, such as AFib, they may recommend continuous heart monitoring to record your symptoms and episodes as they occur over an extended period of time.

Symptoms of AFib can include:

  • Racing, pounding heart
  • Erratic pulse
  • Feeling worn out, fatigued
  • Shortness of breath
  • Trouble with normal exercise and activities
  • Chest pain or pressure
  • Lightheadedness, dizziness and fainting

Many people who have AFib may not experience these symptoms. It is important for your doctor to accurately diagnose your condition and understand how often and how long it occurs.
