A new clinical study shows that PulseAI’s deep learning AI demonstrates superiority over the Apple Watch ECG in the detection of atrial fibrillation. Results have been accepted for presentation at the Heart Rhythm Conference, which is set to be held May 19 to 21, 2023.

PulseAI said the study was conducted by a clinical team from Beacon Hospital in Dublin, Ireland.

The primary objective of the study was to assess the accuracy of AF detection using the Apple Watch companion application (ECG App 2.0) when compared to PulseAI's proprietary AI algorithm. The team sought to determine if the Apple ECG Algorithm was failing to detect important cases of Afib.

The results of the study clearly demonstrated that the PulseAI Algorithm significantly outperformed the Apple Watch ECG algorithm by increasing the sensitivity for AF detection by an impressive 18%. Moreover, PulseAI was able to provide a conclusive diagnosis for more patients by reducing the number of unclassified readings from 10% to less than 1%.

"We are thrilled to announce that our AI algorithm has proven to be far more accurate in detecting atrial fibrillation than even the latest Apple Watch ECG algorithm," said PulseAI CEO and Founder Alan Kennedy. "Smartwatches with built-in ECG sensors have become increasingly popular, but accurate interpretation of the data from these devices remains a significant challenge. Our breakthrough AI-ECG technology promises to provide numerous benefits for both patients and physicians by enabling the accurate interpretation of smartwatch ECG readings at scale, helping pave the way for accurate and efficient remote patient monitoring".

Apple won FDA clearance for its ECG app in for the Apple Watch Series 4 in 2018. The big tech company has since been embroiled in an ECG patent spat with AliveCor. In December, the USPTO’s Patent Trial and Appeal Board ruled the built-in ECG technology within some Apple Watches infringed on some of the Mountain View, CA-based company’s technology.

The big tech giant was also involved in a trade secret fight with Masimo over smartwatch technology. Irvine, CA-based Masimo accused Apple of “poaching employees and stealing trade secrets for the Apple Watch,” according to a report from macrumors.com.

Earlier this month, the suit in a mistrial – when a jury was unable to reach a verdict.
