Machine learning, a key aspect of artificial intelligence (AI), may improve the diagnosis of heart disease by analyzing large amounts of data from chest CT scans, echocardiograms, and electrocardiograms. By recognizing patterns, the machine "learns" and becomes more accurate over time. Current projects include diagnosing coronary artery disease with stress echocardiography and detecting multiple heart rhythm disorders from electrocardiograms in different formats and layouts.

A 2022 study suggests that using a smartwatch capable of estimating blood oxygen levels and recording an electrocardiogram could be an effective way to remotely monitor people at home following a minimally invasive heart valve replacement.

With home monitors, smart watches, and other wearable tech, patients are increasingly bringing their own data to physical exams. Learn the benefits and drawbacks of all of this data—and when/if it can help with health recommendations.

Some portable electronic devices—including Apple AirPod charging cases and certain smartphones—contain strong magnets that can interfere with the function of an implantable cardioverter-defibrillator.

Virtual reality (VR) is being studied as a therapy for people with chronic pain. It immerses people in calming three-dimensional environments and uses principles of mindfulness, meditation, guided imagery, or cognitive behavioral therapy. It's believed to help reduce chronic pain by decreasing stress, anxiety, depression, and fear, which all contribute to pain. It could also be that VR and its many stimuli simply distract your brain from receiving pain signals. VR for pain reduction isn't widely available as of 2022.

The FDA recently moved to help make certain that women considering breast implants have a clear picture of what implants involve before moving ahead with surgery. The agency announced a series of changes in October 2021. These include new labeling requirements for breast implant manufacturers, a requirement that facilities provide patients with a checklist outlining potential risks and benefits related to breast implants, and updated screening recommendations to detect leaks in silicone breast implants.

Certain devices that use magnetic chargers may interfere with cardiac devices such as pacemakers. A doctor should advise people on which ones to avoid or to use caution when operating.

When a smart watch alert suggests that person's heart rate is below 40 beats per minute, it could be an error, especially if no symptoms are present. But it could signal a heart problem called bradycardia that has many possible causes.
