ClinConnect Summary

This clinical trial is exploring a new way to find out where certain heart rhythm issues, known as tachyarrhythmias, start in the heart. These issues can include conditions like atrial flutter and atrial fibrillation, which may cause the heart to beat too quickly or unevenly. The researchers are using a technique called Magnetocardiography (MCG), which is a non-invasive test that measures the magnetic fields produced by the heart, to help doctors better diagnose these conditions and plan effective treatments, especially for a procedure called radiofrequency ablation that helps correct these irregular heartbeats.

To participate in this trial, you need to be between 18 and 79 years old and have been diagnosed with one of the specified heart rhythm conditions. It's important that your condition is stable and that you can undergo MCG testing. However, certain health issues, like severe heart disease or other serious medical conditions, may prevent you from joining. If you decide to participate, you will undergo the MCG test, which is painless and does not involve any needles or incisions. This research aims to improve how we understand and treat these heart rhythm problems, which could lead to better outcomes for patients in the future.
