Abstract:
1. A non-transitory computer-readable storage medium storing a set of instructions capable of being executed by a smartphone having an accelerometer, that, when executed by the smartphone, causes the smartphone to record a seismocardiogram (SCG) from the smartphone's accelerometer by detecting vibrations on a patient's chest corresponding to heart motion for a first time period, further wherein the set of instructions, when executed by the smartphone, cause the smartphone to do at least one of: analyze the SCG to determine an index of cardiac function, display the SCG, transmit the SCG, or store the SCG, wherein the set of instructions, when executed by the smartphone, causes the smartphone to analyze the SCG to determine the index of cardiac function by taking a ratio of the sum of isovolumetric contraction time (ICT) and isovolumetric relaxation time (IRT) divided by the left ventricle ejection time (ET).
