Cardiac monitoring of dogs via smartphone mechanocardiography: a feasibility study [PDF]
BioMedical Engineering OnLine, 2019 Background In the context of monitoring dogs, usually, accelerometers have been used to measure the dog’s movement activity. Here, we study another application of the accelerometers (and gyroscopes)—seismocardiography (SCG) and gyrocardiography (GCG)—to ...

Multiclass Classifier based Cardiovascular Condition Detection Using Smartphone Mechanocardiography [PDF]
Scientific Reports, 2018 AbstractCardiac translational and rotational vibrations induced by left ventricular motions are measurable using joint seismocardiography (SCG) and gyrocardiography (GCG) techniques. Multi-dimensional non-invasive monitoring of the heart reveals relative information of cardiac wall motion.

Heartbeat Detection in Gyrocardiography Signals without Concurrent ECG Tracings [PDF]
Sensors, 2023 A heartbeat generates tiny mechanical vibrations, mainly due to the opening and closing of heart valves. These vibrations can be recorded by accelerometers and gyroscopes applied on a subject’s chest.
