This technology enables real-time arrhythmia detection using a wearable ECG patch, solving a key problem with current devices that must transmit large amounts of raw heart data, which quickly drains battery life. By sending only compact, encoded features instead of full waveforms, it drastically reduces data volume and power use, supporting long-term continuous monitoring on small, battery-powered devices.
Background: Continuous arrhythmia monitoring with wearable ECG sensors is limited by the large data volumes required to transmit raw or compressed waveforms, which consume significant power and shorten device lifespan. Battery-powered wearables struggle to support long-term operation because frequent recharging interrupts monitoring, reduces compliance, and burdens users. Existing compression techniques still demand substantial computation or sacrifice diagnostic detail, making it difficult to achieve reliable real-time detection under tight energy and bandwidth constraints.
Technology Overview: The invention uses a Smart ECG Patch that acquires ECG signals, detects R-peaks, removes artifacts, and encodes each cardiac cycle into 14 integer parameters representing QRS morphology and instantaneous heart rate. This compact representation is transmitted via low-power Bluetooth to a host device, where a BiLSTM-based classifier performs real-time arrhythmia detection across seven categories. The system incorporates adaptive power management and secure transmission using ECC cryptography and AES-128 encryption, enabling efficient, continuous monitoring.
