heart rate

I'll be honest. Vague phrases like "inner balance," "emotional resilience," and "coherence zone," all of which HeartMath uses to describe its new heart rate monitor and corresponding app, aggravate me a bit. After test-driving the product this week, however, I can overlook the language.

Think of the system as a mobile meditation guide. Available as of yesterday on iTunes, HeartMath's free Inner Balance app works exclusively with its Inner Balance earlobe sensor for iOS ($99), which is available at the company's online store or through many major retailers. It uses emWave technology to show the user's heart rhythm pattern (HRV) and trains the user to change that pattern to a healthier, "coherent" state.

The system is easy to set up and, more importantly, use regularly. After installing the app, simply clip the sensor to your earlobe, plug it into your iPhone or iPad using a standard 30-pin connector (you'll need a Lightning-to-30-pin adapter for iPhone 5), and tap the screen to start.… Read more

Cardio med tech company Biotronik today announced Food and Drug Administration approval of the world's first implantable cardiac defibrillator that uses just one lead to sense atrial arrhythmias.

Say what?

For those unfamiliar with the mechanics of the heart, let's back up. Atrial fibrillation (AF), the most common heat arrhythmia, occurs when the electrical signals in the atria (the heart's two upper chambers) fire fast and frenetically, causing the atria to essentially quiver instead of pulse regularly, which can result in blood pooling or clotting and thus greatly increase the risk of stroke and congestive heart failure.… Read more

Researchers at Boston Children's Hospital had the bright idea that, since kids with anger-control problems tend to resist psychotherapy but enjoy video games, the researchers should develop a game that sneakily helps kids practice emotion-control skills -- and in the process perhaps reduces the need for medication.

The game, called RAGE Control (short for Regulate and Gain Emotional Control), employs a finger heart rate monitor; users with elevated heart rates actually lose the ability to shoot enemy spaceships. Researchers say the idea is to teach kids to better control their emotional responses -- and specifically to reduce outbursts of … Read more

Your smartphone could soon become a combination personal trainer and DJ.

Thanks to headphones that can measure your heart rate and acceleration, and a smartphone app that can identify which songs on your phone will help you reach your target heart rate, you won't have to guess which playlist best suits your next jog.… Read more

If you're not afraid to swallow your technology, you may want to check out new tech cleared by the Food and Drug Administration this week that lets you ingest a digital sensor powered by stomach acid that alerts your doctors about your health and your treatment habits.

The technology consists of a tiny, silicon-based sensor that, at 1mm wide (roughly the size of a grain of sand), can be consumed via pills and pharmaceuticals and pass through the body much like high-fiber food.

According to the developer, Proteus Digital Health, once the sensor is swallowed, stomach fluids that come into contact with it provide enough power to relay a signal that documents exactly when it was taken. This data is transmitted to a battery-powered patch worn on the skin that detects the signal and records the exact time the sensor was swallowed.… Read more

Perfect for outdoors enthusiasts, Google's My Tracks app records your path, speed, distance, and even elevation while you walk, run, bike, or do anything else that a GPS signal can follow. And for those who are a bit more serious about their training, the app even lets you hook up with a few third-party Bluetooth biometric sensors, including Zephyr HxM, Polar WearLink, and ANT+ monitors.

To get started, just open up My Tracks and hit the record button at the top of the screen. From there, so long as you have a strong GPS signal, My Tracks will plot … Read more

Workers cut off from office e-mail for five days exhibited more natural, variable heart rates and toggled between screens less frequently than those with e-mail access, according to new research out of the University of California, Irvine, and the Army's Natick Soldier Systems Center near Boston.

The "A pace not dictated by electrons" study of 13 civilian employees at the Army center is undoubtedly small, and the results, presented this week at a meeting of the Association for Computing Machinery in Austin, Texas, are only preliminary. Still, researchers say the findings were surprisingly consistent in favor of … Read more

Being obese can bring on a wide range of health complications, some less obvious than others.

So when a physician in Houston asked bioengineering students at Rice University to help relieve his obese patients' burden of breathing during surgery, the idea "sounded a little weird," said senior Norman Truong, according to a press release. But his team, calling themselves R-Aides, took on the challenge.

The resulting device literally lifts the burden obese patients carry on their abdomens during surgery by using a simple suspension device that consists of suction cups attached to a horizontal beam and tied in … Read more

Scientists and engineers have built a monitor that tracks heart rate, respiration, and movement--without requiring direct contact with skin.

The "life and activity" monitor, developed at Oregon State University, is wearable and non-invasive. The team worked with researchers at the University of California at San Diego to develop a noncontact sensor that is essentially an electric field sensor for tracking the heart rate through materials such as clothing.

The sensor also includes a 5-axis inertial measurement unit that allows for ongoing and simultaneous monitoring of movement, heart rate, and respiration. Imagine adhering such a device to your pants … Read more
