Signal Quality Assessment of a Novel ECG Electrode for Motion Artifact Reduction

Sensors, 2021
Background: The presence of noise is problematic in the analysis and interpretation of the ECG, especially in ambulatory monitoring. Restricting the analysis to high-quality signal segments only comes with the risk of excluding significant arrhythmia ...

Accuracy of pulse interval timing in ambulatory blood pressure measurement [PDF]

, 2016
Blood pressure (BP) monitors rely on pulse detection. Some blood pressure monitors use pulse timings to analyse pulse interval variability for arrhythmia screening, but this assumes that the pulse interval timings detected from BP cuffs are accurate ...
