Evaluation of Electrocardiographic Measurements by High Density Electrode ECG
University Hospital, Bordeaux
1,800 participants
Apr 6, 2021
INTERVENTIONAL
Summary
Cardiac electrical activity is detected on the body surface with conventional electrocardiography involving 12 leads (ECG 12). A limitation of the current ECG technique is that recordings are obtained from only 6 independent precordial leads pairs ; which may miss cardiac potentials from spatially limited regions. More extensive sampling of the body surface may contribute to additional clinical information. The present study investigates the additional sensitivity of ECG using 128 body surface leads (High Density (HD) ECG) in measuring global or regional cardiac activity.
Eligibility
Inclusion Criteria3

- Patients managed for prophylactic ventricular defibrillator implantation, according to international recommendations: Heart disease with ejection fraction < 35%, heart disease with sustained ventricular tachycardia, cardiomyopathies with high rhythmic risk,
- Women of childbearing age with effective contraception.
Exclusion Criteria2
- patients under 14 years old,
- pregnant or nursing woman.

Interventions
This experimental procedure is a passive, non-invasive, high-density surface ECG recording using 128 skin electrodes.The electrodes are positioned on strips of 10 electrodes to be prepared with adhesive tape and coated with conductive gel before installation on the patient. The total duration of the acquisition is 10 to 30 minutes.
This standard 12-lead ECG is defined on the HD ECG, from electrodes F13, G3, G14, H5, H15, H25 corresponding to the precordial electrodes. 4 limb electrodes will be added for the frontal leads. Thus, the HD and 12-lead ECGs will be obtained simultaneously.
