The Seismofit® System
Estimate VO₂max with our revolutionary Seismofit® System, which combines advanced seismocardiography technology with an AI algorithm. This groundbreaking solution delivers VO₂max estimates that match the accuracy of the gold standard, but at a fraction of the cost and time, making it accessible to everyone. The seamless integration of the sensor, app, patch, and algorithm makes this possible, providing a highly effective and affordable way to assess cardiovascular fitness with precision and reliability.
Seismofit® sensor
The Seismofit® sensor captures seismocardiographic vibrations, finely tuned to each heartbeat. These vibrations, transmitted through the chest, carry a distinct signature that elucidates the dynamics of valve movements and heart chamber contractions.
Seismofit® patch
Complementing the sensor, the Seismofit® Patch ensures precise fixation at the distal sternum. Crafted with hypoallergenic adhesive and equipped with release liners, the patch provides secure attachment while prioritising user comfort during seismocardiography sessions.
Seismofit® app
Seamlessly integrated with mobile devices, the Seismofit® App serves as the control centre for seismocardiography recordings. Available on app stores, the Seismofit® App guides users securely through the recording process, utilising instructive images for an intuitive experience, and ultimately displaying the user’s VO₂max score.
Seismofit® algorithm
Driving the analysis on the VentriJect server, the Seismofit® algorithm transforms recorded vibrations into a meaningful equivalent—the VO₂max score. Leveraging AI and key heart features such as timing, morphology, amplitude, peak-to-peak ratios, and heart rate variability, this algorithm ensures precise and reliable results.
“SCG based estimation of V̇O2max is novel, low cost, easy to use and accurate estimation method of CRF with a high level of reproducibility. It can potentially facilitate cardiorespiratory fitness becoming an integrated part of modern health assessment.”

Data security and compliance with GDPR
At VentriJect, safeguarding your personal data is our top priority. We strictly adhere to the General Data Protection Regulation (GDPR) and comply with ISO27001 standards. Our data processing activities are transparent, ensuring your privacy. We collect only essential data points—weight, age, height, and VO₂max score—keeping all tested individuals anonymous.
The key to linking the VO₂max value with your personal data lies exclusively with the person conducting the measurement. VentriJect has no way of accessing this key, ensuring complete data privacy.
We do not share or sell your personal data with any third parties. For any inquiries or to exercise your rights, please contact us at contact@ventriject.com or through our website. We ensure timely responses within one month, with the possibility of extension up to two months if required due to complexity or volume.
Seismofit®: The Better Alternative to Conventional VO₂Max Testing
No physical exhaustion required
Seismofit® offers a VO₂Max measurement method that eliminates the need for intense physical exertion. Traditional methods often require participants to push themselves to exhausting levels, which can be challenging for those not accustomed to strenuous exercise or physically unable to complete the required tasks for various reasons. With Seismofit®, users can measure their VO₂Max comfortably while lying down, making the process more accessible and less physically demanding for everyone.
Precise and Reliable
Seismofit® addresses common imprecision issues found in traditional methods, such as instrument variability, environmental conditions, and individual respiratory patterns. These factors often contribute to variances in VO₂Max estimations, making consistent and reliable results challenging to achieve. By offering a more controlled and less variable testing environment, Seismofit® ensures greater accuracy and dependability in VO₂Max measurements.
No calibration needed
Traditional VO₂Max testing methods require routine calibration to maintain measurement accuracy, demanding meticulous practices to minimize potential errors. Seismofit® simplifies this process by eliminating the need for routine calibration, ensuring consistent and accurate measurements with minimal effort.
Simple to use
Traditional VO₂Max testing methods require highly trained staff to perform the tests and interpret the measurements. The Seismofit® sensor and app are simple to use, ensuring reliable and accurate results without the need for specialized training or constant calibration. This makes the process more accessible while maintaining high standards of precision.
