Assessing the accuracy of Seismofit® as an estimate of preoperative maximal oxygen consumption in patients with hepato-pancreato-biliary, colorectal, and gastro-oesophageal cancer [PDF]
BJA OpenBackground: Peak oxygen uptake (VO2 peak) measured during cardiopulmonary exercise testing (CPET) is commonly used to objectively assess fitness and inform risk stratification. Preoperative CPET is not always universally available.

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 ...

Identifying Patients With Coronary Artery Disease Using Rest and Exercise Seismocardiography [PDF]
Frontiers in Physiology, 2019 Coronary artery disease (CAD) is the most common cause of death globally. Patients with suspected CAD are usually assessed by exercise electrocardiography (ECG). Subsequent tests, such as coronary angiography and coronary computed tomography angiography (

Challenges in using seismocardiography for blood pressure monitoring [PDF]
Computing in Cardiology Conference (CinC), 2017 The capability of continuously and non-invasive blood pressure (BP) monitoring is valuable in the clinical setting. Pulse transit time (PTT) has shown the promise to track changes in the arterial BP. This study examines the efficacy of seismocardiogram (SCG) and photoplethysmogram (PPG) combination for timing the proximal and distal pulse respectively ...

Seismocardiography Pig Hypovolemia Dataset for Signal Quality Indexing and Validated Cardiac Timings [PDF]
Scientific DataSeismocardiography (SCG), a non-invasive method for capturing cardio-mechanical signals, is often susceptible to noise and motion artifacts. Current approaches primarily use automated algorithms and machine learning techniques for signal quality indexing
