Diffusely increased arterial compliance with a marked reduction in pulse wave velocity and decreased systemic vascular resistance.

Marked resting tachycardia caused by enhanced myocardial sensitivity and upregulation of beta-adrenergic receptors. Significant acceleration of early diastolic left ventricular filling (E wave elevation) accompanied by atrial fibrillation in over 80% of healthy octogenarians.
