Wearable/Wireless | 3D Seismocardiography
Researchers have been investigating the use of a promising, yet not entirely understood technique known as seismocardiography. This method takes advantage of natural vibrations produced by the cardiovascular system by recording with accelerometers, and using obtained data to make inferences about the state of health of the subject. Its use has shown promise as a noninvasive technique to measure heart health in both clinical and ambulatory environments. Researchers Paukkunen et al. have recently studied the three-dimensional vibration patterns of the cardiovascular system in an attempt to quantify them and make connections to the health of their subjects. To supplement their data, the researchers used a BIOPAC ECG amplifier and wireless respiration transducer to gain insight into the cardiovascular health of participants. Data was collected and analyzed from both a group of healthy subjects as well as a group of those affected by atrial flutter. The accelerometer and ECG/Respiration data was analyzed with AcqKnowledge, in an effort to understand more about the 3D vibration patterns and their use as indicators for disease. What the researchers found was that the data did differ significantly between the healthy subjects and those with heart flutter. How the data differed was in the relative location of these vibration events occurring in different parts of the cardiovascular system. By comparing to consistent cardiology data, the researchers were able to produce results that suggested that spatial distribution of seismocardiographic events. BIOPAC Systems offers these solutions and others for cardiology, with products designed for reliable, consistent data acquisition and analysis for wireless and wearable use in a variety of environments. This research sets the stage for further investigation into the potential use of seismocardiography to catch signs of heart disease easily and affordably, providing a new weapon for our long-lasting battle for cardiovascular health.
