title: Pre-ejection period by radial artery tonometry supplements echo doppler findings during biventricular pacemaker optimization
abstract: An acute shortening of PEP by radial artery tonometry occurs post Biv pacemaker optimization and correlates with improvement in hemodynamics by echo Doppler and may provide a cost-efficient approach to assist with Biv pacemaker echo optimization.
