Atrial fibrillation is often asymptomatic and intermittent making its detection challenging. A
photoplethysmography (PPG) provides a promising option for atrial fibrillation detection …

More than a century has passed since Einthoven laid the foundation of modern
electrocardiography and in recent years, driven by the advance of wearable and low budget …

Many of the existing electrocardiogram (ECG) toolboxes focus on the derivation of heart rate
variability features from RR-intervals. By doing so, they assume correct detection of the QRS …

Traditional methods to evaluate the human motivation in companies include surveys,
statistical techniques and psychological analysis. However, generating the required …

This paper describes a robust method for heart beat detection from noisy electrocardiogram
(ECG) signals. Generally, the QRS-complex of heart beat is extracted from the ECG using a …

Instantaneous heartbeat detection is necessary for an optimal patient monitoring in
healthcare centers. Whereas electrocardiogram (ECG) and ballistocardiogram (BCG), for …

Background Detecting asymptomatic and undiagnosed atrial fibrillation (AF) is increasingly
important. Recently, we developed a wristwatch‐based pulse wave monitor (PWM; Seiko …

Obstructive sleep apnea is a common sleep disorder with a high prevalence and often
accompanied by significant snoring activity. To diagnose this condition, polysomnography is …

This paper introduces a noise robust real time heart rate detection system from
electrocardiogram (ECG) data. An online data acquisition system is developed to collect …

A ferroelectric-based (FE-based) non-volatile flip-flop (NWF) is proposed for low-power LSI.
Since leakage current in a logic circuit can be cut off by non-volatile storage capability of …
