Creation of an ECG Database in 3T MRI With Healthy Heart and Several Kind of Cardiac Disease.

Central Hospital, Nancy, France19 enrolled

Overview

The aim is to create a database including recordings of ECG data recorded in an MRI acquisition

ECG monitoring is an essential tool during MRI, especially for cardiac MRI (CMR). Indeed, the system needs to synchronize the acquisitions on the cardiac cycles. To identify the cycle, the system is based on the ECG. Furthermore, patients having a CMR can be at risk of presenting cardiac rhythm troubles, and must be monitored with a trustable system. The problem is that in MRI, a lot of artefacts occur, leading to dramatic disturbances of the signal. A lot of tools are used to try to remove the artefacts. The aim of this study is to create a database that can be used to test the different tools to remove the artefacts. The investigators intend to include all types of ECG patterns that can exist, to allow to test the tools in all situations.
