Clinical validation of a low-power and wearable ECG patch for long term full-disclosure monitoring.

Background: Detection of intermittent atrial fibrillation (AF) is done using a 24-h Holter. Holter recordings are powerful but lack the comfort and have limited recording times resulting in under diagnosing of intermittent AF.

Objective: Within this work we evaluated and compared a novel miniaturized three-channel ECG monitoring patch versus a 24-h Holter system.

An optimized DSP implementation of adaptive filtering and ICA for motion artifact reduction in ambulatory ECG monitoring.

Noise from motion artifacts is currently one of the main challenges in the field of ambulatory ECG recording. To address this problem, we propose the use of two different approaches. First, an adaptive filter with electrode-skin impedance as a reference signal is described.
