What is an ECG? 

ECG, or electrocardiogram, is the graphical representation of the electrical activity of the heart. 

With each heartbeat, an electrical wave travels through your heart. This wave causes your heart to contract and pump blood.

In a doctor’s office, a standard 12-lead ECG is usually taken. This 12-lead ECG records electrical signals from different angles in the heart to produce twelve different waveforms. The deviceBeamO measures a waveform similar to one of those twelve waveforms. This configuration is known as single-lead ECG.

The BeamO's 1-lead ECG is able to provide information about heart rate and heart rhythm and enables classification of Atrial Fibrillation (AFib) (EU only). However, a single-lead ECG cannot be used to identify some other conditions, like heart attacks. Single-lead ECGs are often prescribed by doctors for people to wear at home or within the hospital so that the doctor can get a better look at the underlying rate and rhythm of the heart.

ECG classifications (EU Only): 

After an ECG recording, you will see one of the following classifications for the recording in the Withings App (cf. left picture of the figure below) and on the BeamO screen (cf. right picture of the figure below):

• Low Heart Rate (heart rate < 50 bpm): A Low Heart Rate result means your heart is beating less than 50 beats per minute (bpm). This recording cannot be classified by the device. A low heart rate can happen if electrical signals are not properly conducted through the heart. Some medicines can also cause a low heart rate. Talk to your doctor if you have questions about your ECG recording.

   

• High Heart Rate (heart rate > 150 bpm): A High Heart Rate result means your heart is beating above 150 beats per minute (bpm). This recording cannot be classified by the device. Many different things can cause a high heart rate. A heart rate may be high because of exercise, stress, dehydration, infection, AFib, another arrhythmia or another cause. Talk to your doctor if you have questions about your ECG recording.

• Sinus Rhythm (heart rate between 50-99 bpm): A Sinus Rhythm result means your heart rate is between 50 and 99 beats per minute (bpm) and is beating regularly.

• High Heart Rate (No signs of Afib - between 100-150 bpm): A High Heart Rate (No signs of AFib) result means the heart rate is beating between 100 and 150 beats per minute (bpm) and does not show any signs of Atrial Fibrillation. Many different things can cause a high heart rate. A heart rate may be high because of exercise, stress, dehydration, infection, an arrhythmia, or another cause. Talk to your doctor if you have questions about your ECG recording.

   

• Atrial Fibrillation (heart rate between 50-99 bpm): An Atrial Fibrillation result means the heart rate is between 50 and 99 beats per minute (bpm) and is beating irregularly. If you have not been diagnosed with AFib before, you should talk to your doctor.

• Atrial Fibrillation - High Heart Rate (heart rate between 100-150 bpm): An Atrial Fibrillation — High HR result means your heart rate is beating between 100 and 150 beats per minute and is beating with an irregular pattern. If you have not been diagnosed with AFib before, you should talk to your doctor.

• Inconclusive: An Inconclusive result means that the signal cannot be classified as Sinus Rhythm or Atrial Fibrillation, although the quality of the recording is good. This may be due to various conditions, including but not limited to other arrhythmias or other heart conditions. Talk to your doctor if you have questions about your ECG recording.

• Poor Recording: A poor recording result means the recording quality is low and the ECG cannot be classified. Some things that can cause this type of result are excessive movement that cause a signal of poor quality; or proximity to an electrical device that generates strong electromagnetic fields; OR not following best practices for the gestures to be adopted; A small percentage of people may have certain physiological conditions that prevent them from creating enough signal to produce a quality recording. You may try to re-record your ECG. You can review how to take an ECG during setup or by tapping Take a Recording in the ECG section of the Withings app on your smartphone. If you think you may be having a heart attack (myocardial infarction) or are facing a medical emergency, call the emergency services.

 NOTES: 

• The classification of the ECG recording is for informational use only. It is meant to supplement, but not replace, traditional diagnosis methods. If you are experiencing any symptoms or have concerns, contact your physician. If you believe you are experiencing a medical emergency, contact emergency services.
• The heart rate output is the median [AVERAGE] value of the beat-by-beat heart rates over the 30 seconds of the recording.
