Using the developed algorithm, the team identified an electrocardiographic signature during normal sinus rhythm that could predict with excellent accuracy an AF diagnosis (with area under the curve of 0.84, sensitivity 76.1%, specificity 76.4% and overall accuracy of 76.4%).Ībout 20% of patients with a stroke from AF were unaware of AF prior to the stroke diagnosis. The team used a cohort of 77,428 Mayo Clinic patients to develop and test the AI algorithm. Kapa's team is currently exploring the application of AI algorithms to the ECG in sinus rhythm to screen for occult atrial fibrillation (AF).

Mayo Clinic cardiology's use of AI to detect asymptomatic left ventricular dysfunction from the surface electrocardiogram (ECG) was discussed in Mayo Clinic Cardiovascular Update in 2019, based on the team's research published in Nature Medicine in 2019.ĭr. The Cardiovascular Innovation Laboratory is fully immersing itself in AI and applying AI to the many different facets of its current practice. AI has already shown tremendous promise, with the Food and Drug Administration approving three AI medical devices last year. Artificial intelligenceĪrtificial intelligence (AI) has the ability to detect and recognize patterns that elude humans, providing unique opportunities to further understand disease pathophysiology, diagnoses and treatments. Future additions to this lab will include tactile and haptic feedback, which will bring realistic touch, force feedback and precise motion tracking. In addition, VR techniques are proving to be a valuable tool in the training of residents and fellows. It has also been successfully applied to help with pre-procedural planning in patients with implanted cardiac devices undergoing extraction. In patients with complex congenital heart disease undergoing cardiac ablation or device procedures, this technology re-creates patient regional anatomy in a 3D space, appreciating subtle patient anatomical variations as well as relationships to collateral structures. This technique provides a remarkably different perspective to both planned procedures and patient care. Kapa and his colleagues use Digital Imaging and Communications in Medicine (DICOM) images from computerized tomography or magnetic resonance imaging to create a virtual 3D space, which provides an immersive and engaging new way to visualize patient images. Gurman’s report suggests that Apple only expects to sell around one headset per store each day.VR clip from patient defibrillation system with cardiac structures stripped awayĬlip from projected VR of patient cardiac device shows combined epicardial-endocardial pacing-defibrillation system with cardiac structures stripped away and projected in 3D space.ĭr. The initial headset is expected to be expensive – even for Apple’s standards – so it will be targeted at high-end creators and developers. In comparison, an iPhone requires up to 3 optical modules running simultaneously and does not require continuous computing.”īack in January, Bloomberg’s Mark Gurman reported that Apple plans to launch a VR headset as a niche “precursor” to mainstream AR glasses. “Apple’s AR headset requires a separate processor as the computing power of the sensor is significantly higher than that of the iPhone.įor example, the AR headset requires at least 6-8 optical modules to simultaneously provide continuous video see-through AR services to users. These displays will require the grunt of the M1 to power. Kuo says the headset will use a pair of 4K Micro OLED displays from Sony for its VR capabilities. However, Kuo’s report suggests Apple’s headset will support both VR and AR. The other rumoured device was more like smart glasses with AR capabilities. One of the reported devices was said to be a standalone VR headset along the lines of the Oculus Quest. Rumours of Apple’s entry into the AR/VR space have been circulating for several years with many reports suggesting that Apple would debut two devices. This chip will handle the device’s more demanding tasks.Ī second, lower-end processor will be used to handle sensor data. One processor is said to be similar to Apple’s debut in-house silicon, the M1. Renowned analyst Ming-Chi Kuo claims Apple’s long-rumoured AR/VR headset will debut next year with “Mac-level” power.Ī research note from Kuo seen by MacRumours suggests the device will feature two processors to support its capabilities.
