Smart, connected implantable measures heartbeat
May 8, 2019
What is claimed to be the world's first smartphone-compatible implantable heart monitor, the Confirm Rx ICM from Illinois-based Abbott Laboratories is said to offer more accurate detection of heart rhythm disorders.
The smart heart monitor for arrhythmia detection is for people at risk from irregular heartbeats. Now with CE Mark in Europe and US FDA clearance, the Confirm Rx insertable cardiac monitor (ICM), a paperclip-sized implantable device, combines smartphone connectivity and continuous, remote monitoring to track unpredictable heart rhythm problems for fast and accurate diagnosis.
An arrhythmia is an abnormal heart rhythm that can lead to symptoms such as the feeling the heart is racing, dizziness, shortness of breath or fainting. Living with an irregular heartbeat can lead to constant questions for people battling symptoms. For the 33.5 million people living with atrial fibrillation (AFib) – the most common arrhythmia – many do not even know they have the condition.
The Confirm Rx ICM is helping advance how physicians remotely monitor arrhythmias in people most at risk. Inserted just under the skin in the chest above the heart during a quick, minimally invasive outpatient procedure, the device is the only ICM on the market that syncs to a smartphone via Bluetooth and transmits information to the physician to help identify irregular heartbeats quickly. Abbott's mobile app eliminates the need for an additional transmitter and is user-friendly health technology translated in nearly 40 languages.
"Through new advances like Abbott's next generation of Confirm Rx ICM, physicians can act more proactively and efficiently in their treatment approach, and patients can stay engaged and connected," said Avi Fischer, medical director of Abbott's cardiac rhythm management therapies.
Wearables used to track cardiac arrhythmias have limitations when it comes to making a clinical diagnosis. Many require recharging at night, which can lead to missing irregular heartbeats that may occur sporadically and infrequently. Others require some level of interaction by the person to record symptoms, which may not be top of mind when feeling light headed, dizzy or experiencing a rapid heart rate.
"The rise in health monitoring has undoubtedly increased awareness of arrhythmias such as AFib, but many of these devices still aren't leading to an improved diagnosis or solving the key clinical challenges for people at risk," said Sean Beinart, a cardiologist with Adventist Healthcare in Rockville, Maryland. "Like a guardian for heart health, Confirm Rx ICM can relay important data about a person's heart rhythm through their smartphone and alert their care team to a potentially dangerous heart event. With Abbott's new technology, I can better identify risk, making it actionable for me and life-changing for my patient."
Unlike other monitoring technology that can lead to gaps in arrhythmia detection, Confirm Rx ICM provides continuous round-the-clock monitoring. The detection technology reduces false detection by 97 per cent and avoids alerting physicians of irregular heartbeats that may not actually signal a cardiac arrhythmia.
The latest version incorporates SharpSense technology, which was designed with physician feedback and insights from the people who have benefited from the Confirm Rx ICM since it was first commercialised in 2017.
Approximately six million Americans are afflicted with irregular heartbeats, including 28-year-old Becca Bartling. Choosing Abbott's Confirm Rx ICM meant she could continue doing yoga, mountain biking and managing a resort on her family's cranberry farm in rural Manitowish Waters, Wisconsin. Bartling said she chose Confirm Rx ICM for its convenience as there was no need for additional monitoring equipment or a recharging station.
There is also no need to rely on the patient to take action, carry a remote or go to sleep next to a separate bedside transmitter. After hearing that her Confirm Rx device would be compatible with an app on her phone, she immediately told her doctor: "I definitely want the Confirm Rx, I want that one. This device is a better option because of my lifestyle."
David Bartling, Becca's husband, recalled a fainting episode during the first week of having the device. "It was the scariest thing that I saw when she would just seem fine and the next thing you know she passed out," he said. "The Confirm Rx helped us feel comfortable with getting answers we were looking for. It's reassuring because it's simple, small and new technology."
Her physician took the data and was able to identify quickly the cause of her fainting: bradycardia, which means her heart was beating too slowly and causing her to pass out. After her accurate diagnosis with the help of Confirm Rx ICM, she received an Abbott pacemaker to manage her condition and allow her to return to harvesting the cranberry farm and leading a fuller life.
