Electro sync

Project Description:

Each year, over 3 million Americans undergo ambulatory ECG monitoring to detect cardiac arrhythmias, often using bulky and uncomfortable devices like Holter monitors. These 12-lead monitors involve 10 adhesive electrodes and many tangled wires, leading to skin irritation, disrupted daily routines, and low patient compliance. This ultimately poses risks of incomplete data collection and missed/inaccurate diagnoses.

ElectroSync is a novel, lightweight ECG monitoring solution designed to dramatically improve patient comfort and diagnostic efficiency. Our device features a centralized electronics hub with 12 custom-length electrode wires optimized for various body types. This design feature also decreases bulk and tangling since unnecessary slack is minimized. The device captures ECG data from three clinically significant leads (Leads I, II, and V2) using only five electrodes—half the number required by traditional Holter monitors—while making minimal compromises such as arrhythmia localization without affecting diagnostic accuracy or false positive rates for three of the most common arrhythmias (Afib, Flutter, and WPW).

The compact circuitry integrates 3 bioamplifiers, an Arduino Uno, and a 9V power supply within a 3D printed housing compartment. Embedded filters and amplifiers ensure high-fidelity signal acquisition, while skin-sensitive electrodes reduce irritation. Additionally, ElectroSync incorporates a dual-branch convolutional neural network trained on over 77,000 ECG recordings to detect arrhythmias including atrial fibrillation, atrial flutter, and Wolff-Parkinson-White syndrome. This AI model is designed to match or exceed the Holter’s 81% diagnostic accuracy and minimize false positives.

All of the hardware components are integrated into a neoprene belt that ensures a secure, lightweight fit for the patient. There is a built-in pouch for the housing compartment, wires are fed underneath the fabric to minimize tangling, and adjustable loops allow for flexibility for various patient body types.

With improved wearability and smart arrhythmia detection, ElectroSync represents a transformative step forward in ambulatory cardiac care.
