“…First MCG signals were registered in 1963 using a set of two copper coils and no external shielding by Baule et al [45]. In 1967, MCG measurement was performed in a magnetically shielded room to cancel out the effects of external magnetic fields such as the earth's magnetic field and that of urban traffic [46].…”

“…However, these sensors are very expensive and not easily operated. On the other hand, an induction coil 4) and a fluxgate sensor 5) can be operated at room temperature; however, they are comparatively large in scale, making it difficult to integrate them in a sensor array. Highly sensitive magnetic field thin film sensors operating at room temperature are useful for biomedical applications or nondestructive evaluation.…”

“…Nowadays, the method to measure electric potential differences on the body surface originating from the cardiomyocytes of the beating heart, known as electrocardiography (ECG), is the most important tool for the diagnosis of heart diseases in clinical routine. The same bioelectric activity that generates electric potentials also induces biomagnetic fields, which were recorded from the heart for the first time in 1963 by Baule and McFee [2]. The method was termed magnetocardiography (MCG).…”

Stan obecny i przyszłe zastosowania B Bo or ri is s L Le ei it th hä äu us se er r 1 1 , , F Fr ri ie ed dr ri ic ch h J Ju un ng g 2 2 , , J Ja ai i--W Wu un n P Pa ar rk k Special article/Artykuł specjalny A b s t r a c tMagnetocardiography (MCG) is a non-contact, non-invasive technique for the assessment of electromagnetic activity of the human heart. Theoretical considerations and comparative studies indicate different information content between MCG and electrocardiography (ECG). Although many questions about cardiac pathophysiology and electrophysiology can be answered by MCG studies, measurement of biomagnetism is still only marginally recognized as a valuable tool. Although MCG instrumentation (SQUIDs, MSR) and operation (liquid helium) are expensive and not available at the bedside, the gain of information drawn from the cardiac magnetic field is worth the effort. The MCG has superior sensitivity for ischaemic myocardium both at rest and under stress. Therefore, it may change one's ideas of decision making about invasive procedures. Compared to scintigraphy, which is a cumbersome method with the need of radioactivity exposure to the patient, MCG is as easy as bicycle ergometry but with higher sensitivity. In terms of risk stratification for sudden cardiac death, it seems to be possible that MCG in the future will provide additional information as to which patient will not benefit from prophylactic defibrillator implantation. However, appropriate clinical studies are lacking. Most interestingly, MCG appears to be practical and informative in the diagnosis of cardiac arrhythmias, and has sufficient spatial accuracy necessary for clinical purposes. It seems realistic that MCG-based localization of arrhythmogenic spots may guide the operator's ablation catheter, e.g. in patients with relapsing AF after a first successful ablation procedure. There is enough room for fantasy which question in clinical cardiology remains to be answered by MCG. K Ke ey y w wo or rd ds s: : magnetocardiography, coronary heart disease, ischaemia, risk stratification, arrhythmia, atrial fibrillation S t r e s z c z e n i e Magnetokardiografia (ang. magnetocardiography, MCG) jest bezkontaktową, nieinwazyjną metodą pomiaru pola magnetycznego ludzkiego serca. Założenia teoretyczne oraz badania porównawcze wskazują, że MCG i EKG dostarczają odmiennych informacji. Pomiar pola magnetycznego jest nadal w niewielkim stopniu uważany za wartościowe narzędzie, pomimo że badania MCG mogą udzielić odpowiedzi na wiele pytań dotyczących patofizjologii serca i elektrofizjologii. Chociaż oprzyrządowanie konieczne do MCG (SQUIDs, MSR) i jego obsłu-ga (ciekły hel) są drogie i nie są dostępne jako badania przyłóżkowe, to informacja uzyskiwana z badań pola magnetycznego serca jest warta tych wysiłków. Magnetokardiografia charakteryzuje się większą czułością w wykrywaniu niedokrwienia miokardium zarówno w warunkach spoczynkow...
