Changes in Regional and Global Cardiac Contractility After Stimulation in Scar Zone with the NOGA System

• Status: Recruiting
• Phase: N/A

Summary

Despite a decrease in voltage amplitude in post-infarction scar areas, greater voltage amplitudes are sometimes observed at the time of local extrasystoles mechanically induced by catheters. However, no study has investigated whether these electrical changes are associated with mechanical changes in local contractility. However, the voltage is closely correlated to the local contractile function as evidenced by the use of the NOGA system.

Conditions

• Myocardial Infarction

Interventions

Type	Name	Description
DEVICE	NOGA TM probe	Each subject will be his own witness since the linear local shortening (LLS) will be measured successively in all patients before, then after stimulation of the scar zone (comparison of LLS measured in sinus rhythm then during stimulation in the scar zone for each patient. Each subject being his own witness and the two recordings being made a few minutes apart, during the same procedure.
