Assessment of Fetal Autonomic Nervous System Activity by Fetal Magnetocardiography

Clinical Medicine Insights: Cardiology, 2008
Aim To clarify the significance of heart rate variability for the evaluation of an autonomic nervous system (ANS) in the normal fetus using fetal magnetocardiography (FMCG). Methods Subjects consisted of normal pregnancy (n = 35) at 28-39 weeks gestation.

Magnetocardiography Combined With the SYNTAX Score for Exploratory Modeling of Clinician-Selected Revascularization Category in Three-Vessel Coronary Artery Disease: A Single-Center Pilot Study. [PDF]

Cardiol Res Pract
Background Three‐vessel coronary artery disease (3V‐CAD) often requires revascularization with either percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). The SYNTAX score is widely used for anatomical risk stratification, but whether magnetocardiography (MCG) provides incremental information beyond anatomical assessment ...

Magnetocardiography in the Evaluation of Sudden Cardiac Death Risk: A Systematic Review

Annals of Noninvasive Electrocardiology, Volume 29, Issue 6, November 2024.
Sudden cardiac death is responsible for 15%–20% of deaths globally/year, predominantly due to VA caused by vulnerable cardiac substrate. Current risk predictors of SCD based on ECG and LV function parameters have significant limitations. Magnetocardiography offers hope for better risk‐prediction, and we evaluated the evidence base for this technology ...

Development of an optically pumped atomic magnetometer using a K-Rb hybrid cell and its application to magnetocardiography [PDF]

AIP Advances, 2012
We have developed an optically pumped atomic magnetometer using a hybrid cell of K and Rb. The hybrid optical pumping technique can apply dense alkali-metal vapor to the sensor head and leads to high signal intensity.

Real-Time Magnetocardiography with Passive Miniaturized Coil Array in Earth Ambient Field

Sensors, 2023
We demonstrate a magnetocardiography (MCG) sensor that operates in non-shielded environments, in real-time, and without the need for an accompanying device to identify the cardiac cycles for averaging.
