Japanese researchers have come up with a way to measure heartbeats remotely, in real time, and under controlled conditions with as much accuracy as electrocardiographs. The technology utilizes spread-spectrum radar to catch signals from the body and an algorithm that distinguishes heartbeats from other signals.

January 26, 2016 — Heartbeats can now be measured without placing sensors on the body, thanks to a new technology developed in Japan. Researchers at the Kyoto University Center of Innovation, together with Panasonic Corp., have come up with a way to measure heartbeats remotely, in real time, and under controlled conditions with as much accuracy as electrocardiographs.

The researchers say this will allow for the development of "casual sensing" — taking measurements as people go about their daily activities, for instance, when they are going to bed or getting ready to start the day.

"Taking measurements with sensors on the body can be stressful and troublesome, because you have to stop what you're doing," said Hiroyuki Sakai, a researcher at Panasonic. "What we tried to make was something that would offer people a way to monitor their body in a casual and relaxed environment."

The added convenience of remote sensing, the team believes, will be an incentive for people to monitor their health status for their own benefit.

The remote sensing system combines millimeter-wave spread-spectrum radar technology and a unique signal analysis algorithm that identify signals from the body.

"Heartbeats aren't the only signals the radar catches. The body sends out all sorts of signals at once, including breathing and body movement. It's a chaotic soup of information," said Toru Sato, professor of communications and computer engineering at Kyoto University. "Our algorithm differentiates all of that. It extracts waves characteristic of heart beats from the radar signal and calculates their intervals."

The team hopes the remote sensing system, with further experimentation, will be put to practical use in the near future.

"Now that we know that remote sensing is possible, we'll need to make the measurement ability more robust so that the system can monitor subjects in various age ranges and in many different contexts," Sato concluded.

The Mesuron Inc. Avalon-H90 uses magnetometers to detect myocarditis in patients without any physical contact. It uses ventricular repolarization dynamics analysis software to look for abnormalities. The vendor said it is more specific than using ECG. It detects the multidimensional dynamics of the electrical activity caused by differences in functions of electrical action potential of normal heart tissues and abnormal ones with hypoxia.

With the advent and optimization of nuclear scintigraphy protocols using bone-avid radiotracers, cardiac amyloidosis caused by transthyretin protein (ATTR) can now be diagnosed noninvasively without a tissue biopsy. The radiotracer 99mTc-pyrophosphate (99mTc-PYP) binds to deposited ATTR amyloid fibrils in the myocardium and can be visualized using planar and SPECT imaging. This is Figure 2, showing how SPECT imaging allows the reader to distinguish between blood pool activity (ventricular cavity, etc) and myocardial activity and identify regional myocardial differences in radiotracer uptake.
