Abstract

Hemodynamic studies during steady states of sitting and walking on a treadmill have shown a fall in mean arterial pressure in 10 of 16 cardiac patients. This was associated with a greater increase in peripheral resistance during sitting, and a failure to increase stroke index during walking. Cardiac index during exercise increased somewhat, largely because of greater acceleration of heart rate.
