TM-12. The TM-12 PC Based Resting ECG / EKG Machine was Designed to Simplify the ECG / EKG Testing Process for Cardiologists, Physicians, Hospitals, Home Health Care, and Urgent Care Facilities

The TM-12 PC Based ECG /EKG Machine is a wireless 12-Lead ECG system and consists of Windows based CardioVu software with interpretation and a "Holter-size" ECG / EKG acquisition device. The TM-12 device wirelessly streams ECG data from the patient to a remote computer such as a PC, laptop or Windows tablet. The process is simple:

  • Perform the electrode placement and lead hookup on the patient in an exam room
  • Visualize and verify ECG lead quality via the LCD of the TM-12 at the bedside
  • Input patient demographic data into the TM-12 CardioVu software
  • Generate the study
  • ECG data is wirelessly streamed to the computer for analysis, interpretation and automatic storage into a database

The entire test can be performed in minutes!

World Renowned Glasgow 12-Lead ECG Algorithm

Telemed Solutions uses the University of Glasgow 12-Lead ECG Analysis Program as the main engine in the TM-12 to output fully Interpretive ECG statements. Reports include Global Measurements, Individual Lead Measurements and Diagnostic Interpretation. The Glasgow Analysis Program was designed with an emphasis toward high specificity and high sensitivity of ECG abnormalities, resulting in report interpretations you can trust.

Among the Glasgow 12-Lead ECG Analysis Program’s many features are: (1) its unique approach to using age, race, and gender, as analysis criteria; (2) its use of neural networks in the diagnosis of myocardial infarction; (3) and a thirteen year development process that improved the pediatric aspect of the program.

It is estimated that over 20 million ECG tests per year are reported worldwide using the University of Glasgow ECG Analysis Program which has been in development over thirty years and continues to be enhanced. The Glasgow algorithm provides automatic centralized Minnesota coding (the internationally agreed standard for epidemiological studies and clinical trials). The algorithm has been involved in numerous clinical studies, and is generally regarded as one of the premiere ECG interpretation algorithms within the cardiology community worldwide.

PC-Based ECG / EKG Instead of dedicated ECG Cart

Most 12-Lead ECG systems are big, bulky carts that contain an ECG screen, keypad, and thermal printer embedded into one dedicated ECG machine. Quality interpretive ECG systems typically come at a higher purchase price and increased operating costs with use of special ECG paper.

Telemed Solutions has developed a way to save physicians money by incorporating computers they already own as part of the TM-12 system. The TM-12 CardioVu software can be installed on any Windows 7 or Windows 8 computer. The TM-12 acquisition device can be attached to a remote patient up to 100 feet away and streams the ECG via Bluetooth to the computer with installed TM-12 CardioVu software. Any Windows 7 or Windows 8 computer in your office can be instantly transformed into a 12-Lead ECG system with a cost that’s about half the price of a traditional interpretive 12-Lead ECG machine.

Light and Compact

The TM-12 ECG acquisition device is the size of a small Holter recorder and weighs less than 4 ounces yet outperforms full-size ECG machines. Its compact design saves space which is a precious commodity in most physician offices and its light weight provides for greater patient comfort and ease of application.

Wireless and Battery Powered

The battery operated TM-12 ECG device is hooked up to a patient and ECG data is wirelessly streamed from the patient to the computer running the interpretation software. The TM-12 is truly portable and designed to use battery power for use in any location, or any room. Two AA batteries will last about one month.

  • Sample 12-lead strips are included to aid technicians in ECG recognition
  • Oversamples each channel at 6000 sps for better Pacer detection (12-lead or any reduced lead hookup)
  • Glasgow 12-lead Analysis at 500 SPS
  • 3 channel mode supports XYZ VCG or reduced lead hookup (Lead I, II, V1)
  • 3-channel mode (I, II, V1) transforms to 7 leads in real-time (I, II, III, aVL, aVR, aVF, V1)
  • 3-channel XYZ mode performs real-time transform to 12-lead (using Dower transform)
