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

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 …

A cutaneous force-frequency relation recording system based on first heart sound amplitude
vibrations has been recently validated. Second heart sound can be simultaneously recorded …

Up-regulation of Ca 2+ entry through Ca 2+ channels by high rates of beating is involved in
the frequency-dependent regulation of contractility: this process is crucial in adaptation to …

Continuous blood pressure (BP) monitoring in daily life is needed to enable early detection
of hypertension and improve its control. Although pulse transit time (PTT)-based BP …

For the early detection of atherosclerosis, it is imperative to explore the capabilities of new,
effective noninvasive diagnosis techniques to significantly reduce the associated treatment …

The modern conceptual revolution in managing patients with stable coronary artery disease
(CAD), based on improvement in preventive and pharmacological therapy, advocates …

BACKGROUND: An important goal of noninvasive stress testing is the identification of
patients with left main coronary artery or three-vessel disease, because coronary artery …

Background/objective: The end-systolic pressure-volume relation (ESPVR) is a useful
method to assess left ventricular contractility during stress providing prognostic information …

Background The degree of pulmonary hypertension is not independently related to the
severity of left ventricular systolic dysfunction but is frequently associated with diastolic filling …
