279 – ECG and EDA Recording in 7-Tesla fMRI

This application note addresses EDA and ECG measurements performed in a Siemens 7T fMRI.

BIOPAC MRI Smart Amplifiers were used to record ECG LEADII and EDA from the fingertips. Standard BIOPAC MECMRI cable sets were used to connect the subject leads, through the MRI patch panel and MRI-RFIF filters, to the equipment control room. The ECG100C-MRI and EDA100C-MRI amplifier, along with MP160 System were situated in the control room.

Associated Applications

• Psychophysiology - Record and analyze BP, ECG, HRV, EDA, EMG, EEG, EOG, RSP, etc. Interface to stimulus presentation programs...use automated analysis routines to easily score and analyze data.
• ECG: Cardiology - Connect up to 16 ECG input leads with MP160 system. Use automated analysis features for HRV, RSA, to classify heartbeats, identify arrhythmias, and perform ECG averaging.
• Magnetic Resonance Imaging with BIOPAC Equipment - Electrodes, electrode leads, transducers, and stimulus options for safe data acquisition in the MRI. Record biopotentials, temperature, respiration, EDA, dynamometry, blood pressure, etc.
• EDA: Electrodermal Activity -
