Your Apple Watch Can Now Be Paired With an FDA-Approved EKG Monitor

In addition to being able to tell time and message friends, the Apple Watch serves as a wearable health and fitness tracker: It can offer workout suggestions, monitor your heart rate, and even help detect sleep apnea in sufferers.

Now, when paired with a third-party band dubbed the AliveCor KardiaBand, it can offer something new to the Apple line: functionality as part of an FDA-approved medical device for EKG monitoring.

To be clear, the Apple Watch itself wasn’t subject to FDA approval: The company doesn’t want to slow down its development schedule by seeking the stamp of a government review process. The approval was granted to the KardiaBand wrist strap accessory, which delivers EKG monitoring that can detect signs of atrial fibrillation (heart arrhythmia) or abnormal heart rhythm by having wearers place a thumb on the band sensor and wait 30 seconds. Unusual readings can then be passed along to your doctor. (The device can differentiate between a high heart rate due to exertion and one outside the boundaries of a body at rest.)

EKG, or electrocardiography, is typically performed only in hospitals, where the heart’s electrical activity can be continuously monitored via skin-placed electrodes. Having the ability to perform the same function at home could provide early warning signs of serious complications stemming from atrial fibrillation, like a heart attack or stroke.

The KardiaBand is available now for $199. While not required, a subscription to AliveCor’s monitoring software adds cloud storage and monthly physician reports and costs $99 annually.

Why Do Some Vaccines Hurt More Than Others?

Whether you experience pain with a vaccine shot may depend on what type you're getting.

Whether you’re planning a trip abroad, have poked yourself with a dirty thorn, or want to prepare for flu season, sitting down for a vaccine shot is not usually a big deal. Barring any fear or apprehension about needles, it’s one quick alcohol swab, a jab into your deltoid, and a bandage.

Some people, however, report that some vaccine shots feel more like a harpoon, with pain upon injection and residual soreness. Does the level of discomfort have anything to do with the vaccine being administered, the patient, or the health care provider?

According to Nancy Messonnier, director of the National Center for Immunization and Respiratory Diseases at the Centers for Disease Control and Prevention, injection pain is a normal consequence of a shot designed to provoke an immune system response. Dr. Messonnier told The Wall Street Journal that inflammation around the injection site is an indication the vaccine is working.

When a vaccine is injected, antigens are introduced into the body. These proteins allow white blood cells to battle against viruses. When they’re jabbed into your arm, your body mounts a defense at the injection site, leading to inflammation.

Some vaccines tend to hurt a little more than others, like ones targeting hepatitis A and B and DTaP (for diphtheria, tetanus, and pertussis). It’s not totally clear why, but it’s possible that additives designed to strengthen the immune system, like aluminum salts or monophosphoryl lipid A, are the culprit. “These are safe ingredients added to the vaccine specifically to create a stronger immune response,” Messonnier told the paper, adding that some people might be more sensitive to them than others.

These additives aren’t the only reason vaccines can sting. The pH level of the solution (which can be acidic), the volume, and the temperature can also affect whether there’s discomfort.

If you or your child are needle-averse, you can try distraction techniques like music, request a numbing cream, or take an over-the-counter pain reliever to combat any post-injection soreness.

Incidentally, the shot probably won’t hurt any more or less if it’s delivered into your buttocks, as was the practice at one time. While some vaccines work well in fatty tissue, like MMR (measles, mumps, and rubella, which gets directed to the fat near your triceps), many do not. And because flu vaccines are often administered in public places like pharmacies, it’s probably best that they stick to your upper extremities.
