In the past decade, there has been a resurgence in the field of unobtrusive
cardiomechanical assessment, through advancing methods for measuring and interpreting …

Cardiovascular disease is a major cause of death worldwide. New diagnostic tools are
needed to provide early detection and intervention to reduce mortality and increase both the …

The electrocardiogram (ECG) has always been an important biomedical test to diagnose
cardiovascular diseases. Current approaches for ECG monitoring are based on body …

The precordial mechanical vibrations generated by cardiac contractions have a rich
frequency spectrum. While the lowest frequencies can be palpated, the higher infrasonic …

Seismocardiogram (SCG) is the measure of the micro-vibrations produced by the heart
contraction and blood ejection into the vascular tree. Over time, a large body of evidence …

Forcecardiography (FCG) is a novel technique that measures the local forces induced on the
chest wall by the mechanical activity of the heart. Specific piezoresistive or piezoelectric …

Gyrocardiography (GCG) is a non-invasive technique of analyzing cardiac vibrations by a
MEMS (microelectromechanical system) gyroscope placed on a chest wall. Although its …

Accurate estimation of seismocardiographic (SCG) signal features can help successful
signal characterization and classification in health and disease. This may lead to new …

This paper presents forcecardiography (FCG), a novel technique to measure local, cardiac-
induced vibrations onto the chest wall. Since the 19th century, several techniques have …

Recently, the ever-growing interest in the continuous monitoring of heart function in out-of-
laboratory settings for an early diagnosis of cardiovascular diseases has led to the …
