Abstract:
 Abstract: Electrocardiogram is an important modality for diagnosis of heart disease, but it may fail to timely and accurately diagnose coronary heart disease and other cardiac conditions. As a non-contact and non-invasive technique, magnetocardiography provides an alternative for predicting and diagnosing heart diseases and allows rapid detection of ischemic cardiovascular disease. So far the measurement of heart magnetic field depends mainly on superconducting quantum interference device (SQUID), which needs to work in liquid helium condition (-269 °C) with high manufacturing and maintenance costs. Herein, we report a pulse pump Rb atomic magnetometer based on optical rotation effect with a sensitivity of 1 pT/Hz1/2. This magnetometer can quickly respond to changes in external magnetic fields. Using this magnetometer, we successfully measured the magnetic signals from the human heart at room temperature, which represents the first successful attempt of measuring cardiac magnetic field using atomic magnetometer in China. This success will promote the advance of research and clinical application of magnetic field measurement.
