Health Condition Terms and Facts

You may be asked to wear a monitor if you have fast, slow or irregular heartbeats. Irregular heartbeat needs to be detected and diagnosed to ensure it’s properly managed and treated. This can be challenging when abnormal heart rhythms and cardiac symptoms may come and go and may not be predictable. That’s why your doctor may want to evaluate your heartbeat over time while you go about your normal activities.

Heart monitors vary in terms of how long they can be used and what information is captured. Preventice offers discreet, patient-friendly monitors that can record irregular heartbeats to give your doctor the data necessary to get answers—and give you peace of mind.

You can be confident that your sensor is monitoring you around the clock. Learn more about your heart monitor here.



The heart has four chambers, two on the right and two on the left:

  • Two upper chambers are called atria (one is an atrium).
  • Two lower chambers are called ventricles.
  • The heart also has four valves that open and close to let blood flow in only one direction when the heart contracts (beats).
  • Normally, your heart contracts and relaxes to a regular beat. Certain cells in your heart make electric signals that cause the heart to contract and pump blood.

What are Cardiac Arrhythmias?

Sometimes, you may feel like your heart skipped a beat, added a beat "fluttering," or is beating too fast (which doctors call tachycardia) or too slow (called bradycardia). Or, you might not notice anything, since some arrhythmias are “silent”. This is known as a cardiac arrhythmia (abnormal heart rhythm), which is among the most common heart disorders.

Heart palpitations are a relatively common and usually harmless condition that the heart feels. While concerning, palpitations usually are harmless. However, in some cases they may indicate a more serious heart condition, like a heart rhythm disorder, which requires treatment. Heart palpitations account for 16 percent of symptoms that cause patients to go to their primary care doctor, second only to chest pain as the reason patients seek cardiology evaluation.1-3

What Is Atrial fibrillation?

Atrial fibrillation (also referred to as AF or AFib) is a common condition of arrhythmia in which the upper chambers of the heart, or atria, quiver faster than the rest of the heart. This means that they beat very fast and irregularly so the heart can’t pump blood effectively to the rest of the body.

AF is a serious medical condition that can significantly increase the risk of stroke over time, could lead to heart failure. Not only can AF negatively impact your quality of life, but those who have AF are five to seven times more likely to form blood clots and suffer a stroke. Fortunately, AF may be treated with medication, cardioversion (a surgical procedure), or a catheter ablation procedure.

What is an ECG?

Our monitors capture the heart's electrical signals through electrodes or patches that are attached to your chest and connected to our device. The resulting captured electrical signals show up on an electrocardiogram, ECG or EKG, recording. It is a painless, non-invasive procedure that records the heart’s electrical activity and can help diagnose arrhythmias. For more information please visit the American Heart Association or The Heart Rhythm Society.

Clinical ECG or EKG, reports are made available to your doctor. In some cases, your doctor may reach out to you to discuss these reports while you’re still wearing the monitor. Other times, your doctor may wish to wait until the end of the prescription to discuss results.
