Magnetocardiography (MCG) is a technique used to measure the magnetic fields produced by electrical activity in the heart.
Historically, the difficulties associated with implementing an MCG system have severely limited the number of applications in use today. CardioFlux has overcome these barriers of the past, and is poised to be easily integrated into clinical workflows.
Although both MCG and ECG measure the electrical activity in the heart, MCG demonstrates major advantages over ECG.
MCG has been known to detect vortex currents that give no ECG signal, creating a better, more holistic view of the electrical activity in the heart.
MCG requires no physical contact with the skin, so any problems arising from skin-electrode contact can be avoided.
MCGs have the potential to give extra information over and above ECGs since they can detect the magnetic field produced by currents in heart tissue.
Magnetocardiography can detect the onset of cardiovascular disease in a very early stage with high accuracy for both acute and asymptomatic patients. Here are three areas where MCG has been and continues to be studied:
Direct diagnosis of heart function after myocardial infarction (MI) and surgery of heart transplantation.²
On-going monitoring of patients with heart surgical intervention: Patients with a stent or who underwent a balloon dilatation; post bypass patients; post heart transplantation patients.³
Detect the cardiac signal of an unborn child starting from the 16th week of pregnancy.⁴
