Super-High Resolution Electrocardiograph

Super-High Resolution Electrocardiograph SHR-ECG. SHR-ECG, Electrocardiograph (EKG)

EDR’s 8-channel processor is able to detect the faint signals from the body’s surface at least down to 6×107 Vp-p. nearly 100% percent of the faint heart beats are measured. 

EDR has developed a more advanced 8-channel Super-Sensitive Neural-Cell Processor (SSNCP). The long-term objective is to exploit the processor’s super-high sensitivity for manufacturing a new breed of diagnostic equipment capable of recording extremely low-level signals from the body surface on a beat-by-beat basis.

There are quite a few additional applications for detection of various small signals that have been developed now that the technology is recognized and financial backing is available. A super-sensitive device on the market provides needed support to researchers worldwide in their desire to test non-invasively or more accurately processes that occur inside of the body. Specifically, inclusion of surface His bundle recordings in the clinical electrocardiogram will provide the opportunity for large population surveys of sufficient magnitude to reveal the early natural history of rhythm and conduction problems we have not yet clinically characterized effectively. There is also potential for using the signal enhancement capabilities of the SSNCP in computerized arrhythmia detection systems.

Invention of a neural-cell in 1977 provided the basis to build the first-of-a-kind 4-channel processor in 1979. Though published results (1-4) were significant and outstanding compared to other investigators work. The P1 continued to work to improve the concept and a more advanced 5-channel processor was devised and built in 1980.From about one hundred consecutive beats, in 76 the His bundle signals were identified. It was noticed that during patients inhaling, the signal of interest in most cases disappears. It is possible that the Surface His bundle (SHB) signal gets smaller when the lung is full of air. Some investigators reported the SHB signal varies on the body surface from l x 10-6 V p-p to 15×10-6 V p-p from one individual to another. The second generation processor, a 5-channel device was able to detect a signal down to 6×10-6 V p-p level that helped to achieve a 76% detection of the SHB signal.

The first device, with 4-channels had a sensitivity of only about 9×10-6 volt p-p. EDR’s 8-channel processor is able to detect a signal at least down to 6×107 Vp-p. nearly100% percent of the beats will be measured.

There are four additional products that have emerged along with the development of the SSNCP processor. A super-low noise preamplifier, a time-variable high-pass filter, a 60Hz digital-comb-reject filter and the new processor or the “brain”. In order to perform an auto and cross-correlation and data relationship analysis in real time they are being produced and offered to bio-medical investigators.
