VSH101 1-Lead ECG Holter


VSH101 is an exceptional chest-pad type 1-lead ECG (Electrocardiogram) device designed to revolutionize patient monitoring. Unlike traditional handheld or watch-type ECGs, this innovative device offers unparalleled convenience and accuracy. Let’s delve into some of its outstanding features:

  1. Hands-free Monitoring: The chest-pad design eliminates the need for hands or fingers to be placed on sensors, making it extremely user-friendly and comfortable for patients during long-term monitoring.

  2. Extended Monitoring: ECG checks often require hours or even days of continuous monitoring. The VSH101’s built-in rechargeable battery ensures an active time of more than 2 days, providing uninterrupted monitoring capabilities.

  3. Superior Sensing: The VSH101 boasts the best performance in the market with its 24 bits resolution and 500 Hz frame rate. This high-quality sensing translates into precise and reliable ECG data.

  4. Customizable Data Output: Users have the flexibility to choose between raw data or filtered data, enabling them to tailor the output according to their specific requirements.

  5. Exceptional CMRR: The device features a Common Mode Rejection Ratio (CMRR) of 70 dB, with a typical 100 dB performance, ensuring accurate measurements even in the presence of common-mode interference.

  6. Motion Artifact Removal: Equipped with a G-Sensor, the VSH101 offers pose detection and motion-artifact removal capabilities, enhancing the accuracy of ECG readings.

  7. Open Protocol and Source Code: For tech-savvy users and developers, the VSH101 provides an open protocol and open-source sample code. This feature empowers users to create their own telemedicine services or applications, expanding the device’s capabilities to suit their unique needs.

  8. Comprehensive Data Retrieval: All the raw data can be easily fetched in CSV file format, simplifying data management and analysis.

  9. Key Parameters: The open protocol offers access to various essential parameters such as G-Sensor data, Heart Rate Variability (HRV), heart rate, and peak detection, providing comprehensive insights into the patient’s cardiac health.

  10. Waterproof and Certified: With an IP42 waterproof rating, the VSH101 is protected against dust and water ingress, making it durable and suitable for various environmental conditions. Additionally, it has passed major ECG device regulations required for certification, ensuring its reliability and safety.

  11. Long-term Monitoring: The device’s large pad and lightweight design make it highly suitable for long-term monitoring applications, ensuring patient comfort throughout extended periods of use.

In conclusion, the VSH101 is a game-changing chest-pad type 1-lead ECG device that combines advanced technology with user-friendly features. Its superior sensing capabilities, hands-free design, extended monitoring duration, and open-source compatibility make it an ideal choice for healthcare professionals and telemedicine service providers seeking the best-in-class ECG monitoring solution.
