Sunnybrook has introduced a new device that uses artificial intelligence (AI) and advanced detection algorithms to enhance the identification and management of irregular heart rhythms.
The BIOTRONIK Biomonitor IV Loop Recorder, recently approved by Health Canada, has already been implanted in five patients at Sunnybrook. The small cardiac monitoring device is used to monitor and record heart rhythms. By enabling timely detection and interpretation of heart rhythm abnormalities, or arrhythmias, implantable cardiac monitors can allow for earlier intervention for arrhythmias and may even prevent severe outcomes including stroke.
“What sets this device apart is its ability to detect “noise”. When a patient moves, has a muscle tremor or there’s a very loud noise, that can fool a traditional device into thinking there’s an abnormal heart rhythm,” explains Dr. Christopher Cheung, cardiologist and cardiac electrophysiologist in Sunnybrook’s Schulich Heart Program. “These ‘smart’ algorithms help our team to filter through the “noise” and exclude it, so we can focus on the really important heart rhythm findings. This is an important step in improving care for patients living with arrhythmias.”
Sunnybrook sees more than 6000 patients a year in its Arrhythmia Device Clinic. Suzette Turner, a nurse practitioner in the clinic, says the intelligent technology is an added boost to the existing benefits of this device.
“Not only do loop monitors provide long term monitoring for up to four years – but they are very small and discreet so patients don’t notice them,” says Suzette, adding the device weighs five grams, and involves a minimally invasive procedure. “Patients benefit as we can quickly pick up on significant arrhythmias enhancing the already substantial capabilities.” This guides decisions about a patient’s medication, other heart devices such as pacemakers or defibrillators, or in deciding if a procedure like a cardiac ablation is necessary.
The Canadian Cardiovascular Society estimates more than 1.5 million Canadians live with heart arrhythmias. With this new technology, Sunnybrook is setting a new standard for detecting and treating heart rhythm disorders across Canada.
