DOI: 10.1161/circ.152.suppl_3.4364631
Abstract: Background: Adjusting left ventricular assist devices (LVAD) pump speed during exercise may enhance hemodynamics and improve functional capacity in patients with advanced heart failure. While intuitively promising, it remains unclear whether speed modulation during exercise… read more here.
