Powerful Features

Transforming ECG for Better Care

  • Faster

    No more placing 10 separate electrodes at specific locations on the body. Proven to save up to 70% of time during setup.

  • Simpler

    Our pre-positioned electrode strip simplifies the setup and placement procedure, enabling everyone to perform a full 12-lead ECG. Detailed data view on the tablet with an on-screen virtual caliper allows for fast lookup of interval and duration for doctors.

  • Better

    Even well trained, experienced technicians make mistakes-- 2% of ECG tests have lead-placement errors that can lead to misdiagnoses. QT ECG eliminates the risk of such errors.

  • Compact and Portable

    This compact and portable ECG device allows doctors or patients to use it anytime, anywhere.

  • Wireless

    Long, disorganized cables are replaced by a simple, one-time-use electrode strip. We have eliminated the risk of errors from connecting the cables, and decreased the risk of infection or contamination.

  • Consistent Test Accuracy

    Eliminates confusion between test result shifts caused by different lead placements versus actual clinical changes. QT ECG increases medical quality.

Now you can get hospital-quality ECG anywhere,
anytime, in the comfort of your home.

Integration and Development


Heart disease is the leading cause of death in US. It is also on of the most preventable. There is an urgent unmet medical need for better cardiac care.
Focusing on innovations in ECG technology, we continue to invest in research and development of products. QT Medical provides complete ECG solution for variety of applications.



At QT Medical, there are many safeguards put in place to ensure the quality and safety of our QT ECG system. Our PCA 500 undergoes diligent and uncompromising testing and evaluation to demonstrate its compatibility and accessibility according to federal and international regulations. We regularly test and update support for new smartphones and tablets. The level of compatibility that allows various units to work together is possible due to standardization. However, certain overtime devices may no longer be supported by Our PCA 500 for various reasons. For a list of compatible devices, please refer to Compatibility List.


Use of QT ECG PCA 500 requires the QT ECG App, and it is available on the App Store and Google Play.

About Us

QT Medical, Inc. is a medical device startup incorporated in 2013. With innovative technologies, we aim to make high quality 12-lead electrocardiogram (ECG) available to everyone. QT ECG, the first product of QT Medical, is the world's most compact 12-lead ECG system. With its simplicity, ease of use, familiar interface by mobile technology, QT ECG is bringing hospital-quality 12-lead ECG to homes. It is optimized for high risk patients who just had coronary artery bypass graft (CABG) surgery, or percutaneous coronary intervention (PCI, i.e. coronary stent). It is also designed for home use by patients with chronic heart failure and arrhythmias.

QT ECG is digital, wireless, and mobile friendly. It is smaller than a deck of cards, fits in the shirt pocket, and works with iOS and Android phones and tablets. More importantly, our patented, proprietary electrodes can save up to 70% time in ECG procedures and greatly reduce errors related to electrode misplacement of and cable connections. In a clinical trial, we found that over 95% of patients with no training, and no experience with ECG, could do a full 12-lead ECG test after reading simple instructions. This revolutionary system will enable patients with heart disease to do timely, high quality 12-lead ECG tests at the convenience and comfort of their homes.

Focusing on innovations in the field of telemedicine and home care, we continue to invest in research and development of products that will bring better cardiac care to patients. Our mission is to improve heart health for everyone through superior technology, and we will not stop working until we reach the goal.
