The ER1-LW Holter ECG allows for 24-hour ECG monitoring to detect abnormal heart function.
Standard ECG measurements take several minutes to complete, which may prove insufficient. Cardiovascular diagnostics require longer ECG monitoring to ensure reliable and accurate results.
The ER1 Holter ECG monitor allows for continuous heart monitoring for up to 72 hours (3 x 24 hours). The ECG monitor works intelligently, detecting irregular heartbeats such as arrhythmia, atrial flutter, and atrial fibrillation.

72h Holter ECG with Screen Analysis PC App
The Holter ECG is equipped with a display that allows the user to check the actual ECG waveform.
By monitoring the ECG waveform on the monitor screen, you can confirm that the Holter has started working and check the signal quality.
Additionally, the holter is equipped with into a touch button. By making short or long key presses, you can control the power switch and access basic settings. This allows for continuous monitoring of the recorder, saving power and extending battery life.

The free AI analysis draws from a database of 300,000 patients and 50 million pieces of analytical data.
To obtain detailed test reports, upload the data to a computer software or app. Then, download the report, analyzed by artificial intelligence, along with the ECG waveform.
The AI-ECG analysis system allows you to identify 17 heart abnormalities:
- Sinus Rhythm
- Ectopic Rhythm
- Sinus Tachycardia (Sinus Tachycardia)
- Sinus Bradycardia (Sinus Bradycardia)
- PAC (Premature Supraventricular Contraction)
- PVC (Premature Ventricular Contraction)
- Couplet of PAC
- Couplet of PVC
- PAC Bigeminy (Bigeminia PAC)
- PVC Bigeminy (Bigeminia PVC)
- PAC Trigeminy (Trigeminia PAC)
