Exploring the Application Value of Magnetocardiography in Detecting Pulmonary Hypertension: A Noninvasive and Visual Approach. [PDF]

Clin Cardiol
MCG may serve as a noninvasive, visualized tool for detecting PH. ABSTRACT Background Exploring accurate and noninvasive methods for detecting pulmonary hypertension (PH) has always been a focal point of research. Owing to its exceptional spatiotemporal resolution, magnetocardiography (MCG) has demonstrated potential value in cardiovascular diseases ...

Case report: Magnetocardiography as a potential method of therapy monitoring in amyloidosis

Frontiers in Cardiovascular Medicine, 2023
Amyloidosis is characterized by a disorder of protein conformation and metabolism, resulting in deposits of insoluble fibrils in various organs causing functional disturbances. Amyloidosis can also affect the heart.

Magnetocardiography Current Source Estimation using Multiple Spatial Filters

, 2021
In this study, cardiac current source localization was simulated using the spatial filter method. We estimated current sources using data from two measurement surfaces, i.e., the front and back of the subject, to reduce the large spatial extension in the

Case report: Recurrence of inflammatory cardiomyopathy detected by magnetocardiography

Frontiers in Cardiovascular Medicine, 2023
BackgroundThe diagnosis of inflammatory cardiomyopathies remains challenging. Life-threatening conditions such as acute coronary syndrome (ACS) always have to be considered as differential diagnoses due to similarities in presentation. Diagnostic methods

Magnetocardiography for fetal arrhythmias [PDF]

Heart Rhythm, 2008
The failing adult heart is known to revert to fetal patterns of contractile protein expression during pathologic remodeling, yet very little is known about the electrophysiology or electromechanics of the living human fetal heart during normal prenatal development or during stress.

Hope in Miniature: The First Case of Implantation of a "Tiny Pacemaker" in Italy as a Successful Treatment for Congenital Atrioventricular Block in a Low Birth Weight Child. [PDF]

Case Rep Cardiol
Congenital complete atrioventricular block (CAVB) is a rare cardiac condition occurring in approximately one in 15,000 to one in 22,000 live births. Maternal autoimmune diseases, with anti‐ssA (Ro) and anti‐ssB (La) antibodies implicated in 56%–90% of cases, are primary causes.

Fe-Based Nanocrystalline Magnetic Shielding Cylinder with Subfemtotesla-Level Magnetic Noise. [PDF]

Adv Sci (Weinh)
Shields with low magnetic noise are achieved by integrating Fe‐based nanocrystalline magnetic shielding cylinders into shielding systems based on μ‐metal. Benefiting from high permeability and low loss factor, Fe‐based nanocrystalline magnetic shielding cylinders effectively suppress magnetic noise. Notably, the magnetic shielding cylinder with the ten‐

A method for noninvasive beat‐by‐beat visualization of His bundle signals

Annals of Noninvasive Electrocardiology, 2023
Background Invasive recording of His bundle signals (HBS) in electrophysiological study (EPS) is important in determining HV interval, the time taken to activate the ventricles from the His bundle. Noninvasive surface measurements of HBS are attempted by
