magnetokardiografiaa

Magnetokardiografiaa is a non-invasive medical imaging technique that measures the magnetic fields produced by electrical activity in the heart. This technique, also known as MEG or MCG, relies on the principle that electrical currents generate magnetic fields, and the heart's electrical signals are strong enough to produce measurable magnetic fields outside the body. Sensitive magnetometers, often superconducting quantum interference devices (SQUIDs), are used to detect these minute magnetic fluctuations.

The magnetic field patterns recorded by magnetokardiografiaa provide information about the heart's electrical activity, including the timing and location of depolarization and repolarization waves. This can help in diagnosing and monitoring various cardiac conditions, such as arrhythmias, myocardial ischemia, and conduction abnormalities. Unlike electrocardiography (ECG), which measures electrical potential differences on the skin, magnetokardiografiaa is less affected by electrical noise from surrounding tissues, potentially offering clearer and more localized information.

The instrumentation for magnetokardiografiaa is complex and typically requires a magnetically shielded room to minimize interference. Despite its potential, magnetokardiografiaa is not as widely used clinically as ECG due to the cost and technical requirements of the equipment. However, ongoing research continues to explore its diagnostic capabilities and refine the technology for broader clinical application.
