Kinetic™ AF ECG Algorithm

AF ECG Algorithm

The Kinetic™ AF ECG Algorithm is designed to be embedded into a device or software suite to provide identification of Atrial Fibrillation/Flutter. The unique design of Kinetic™ AF allows it to be used in ambulatory devices using very small microcontrollers, but still have unparalleled performance to correctly identify AF, with a minimum of false positives.

Atrial Fibrillation is one of the most common arrhythmias, but is often difficult to accurately characterize with an automatic algorithm due to the changing waveform morphology, system or muscle noise. The algorithm addresses the limitations of software size in an ambulatory monitor. Because Kinetic™ AF recognizes the QRS by its intrinsic properties, the code size can be minimized, allowing it to be used in very small devices.

Kinetic™ AF uses a proprietary method for AF detection, and also identifies bradycardia, tachycardia, and pause. The ability to identify all of these rhythms in a small microcontroller makes the Kinetic™ AF ECG Algorithm ideal for embedded ambulatory applications.

Kinetic AF is designed for applications where clinical and technical performance are critical. It can run on any brand of microprocessor using at least 200s/s. It requires only 5 KB RAM for the program, data, and library. As an example, on a commonly used microprocessor with 20 MHz clock set, 8 KB RAM, and 16-bit resolution, it processes each 1 second of ECG data in 10 ms. The processing time is linear to the clock set, so if the clock was set to 40 MHz, the processing time would be 5 ms.

In a recent study using a dataset of 250 records taken from an ambulatory monitoring device and interpreted by 3 Electrophysiologists, Kinetic™ AF provided excellent clinical results.
