Cardiac 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. A single inertial measurement unit (IMU) allows capturing cardiac vibrations in sufficient details and enables us to perform patient screening for various heart conditions. We envision smartphone mechanocardiography (MCG) for the use of e-health or telemonitoring, which uses a multi-class classifier to detect various types of cardiovascular diseases (CVD) using only smartphone's built-in internal sensors data. Such smartphone App/solution could be used by either a healthcare professional and/or the patient him/herself to take recordings from their heart. We suggest that smartphone could be used to separate heart conditions such as normal sinus rhythm (SR), atrial fibrillation (AFib), coronary artery disease (CAD), and possibly ST-segment elevated myocardial infarction (STEMI) in multiclass settings. An application could run the disease screening and immediately inform the user about the results. Widespread availability of IMUs within smartphones could enable the screening of patients globally in the future, however, we also discuss the possible challenges raised by the utilization of such self-monitoring systems.
使用联合地震心动描记术（SCG）和心旋描记术（GCG）技术，可测量左心室运动引起的心脏平移和旋转振动。多维无创心脏监测可揭示心脏壁运动的相对信息。单个惯性测量单元（IMU）可以捕获足够详细的心脏振动，并使我们能够对各种心脏状况进行患者筛查。我们设想使用智能手机心动描记术（MCG）进行电子健康或远程监测，该技术使用多类分类器仅使用智能手机内置内部传感器数据来检测各种类型的心血管疾病（CVD）。这种智能手机 App/解决方案可以由医疗保健专业人员和/或患者自己使用，从他们的心脏进行记录。我们建议智能手机可用于分离正常窦性节律（SR）、心房颤动（AFib）、冠状动脉疾病（CAD）和可能的 ST 段抬高型心肌梗死（STEMI）等心脏状况，以实现多类设置。应用程序可以运行疾病筛查，并立即向用户报告结果。智能手机中广泛存在的 IMU 将来可能使全球范围内的患者都能够进行筛查，但我们也讨论了利用这种自我监测系统可能带来的挑战。
