stenosis or incompetence

cells in SA node
 After age 75 < 10% still functional
• Supports normal cardiac function
– Decrease in number of normal pacemaker
cells in AV node and both bundle branches

membrane to be ready for a second stimulus once it returns to its
resting state following excitation

Aging Changes with the Heart
• Autonomic nervous system (is a part of prepheral NS, and affects
heart rate, digestion, respiration rate, salivation, perspiration, diameter of the pupils, micturition
(urination), and sexual arousal
.
– Decreased responsiveness to beta-adrenergic
stimulation
• Baroreceptors less efficient
• Other aging systems that affect cardiovascular function
– Pulmonary
– Renal
–
Baroreceptors (or baroceptors) are sensors located in the blood vessels of several
mammals.` They are a type of mechanoreceptor that detects the pressure of blood flowing
through them, and can send messages to the central nervous system to increase or
decrease total peripheral resistance and cardiac output.

Congestive Heart Failure
• Pathophysiology
– Loss of contractility of the myocardium →
inadequate cardiac output → activity
intolerance
– Frank-Starling Law
 Overstretching → decreased force of contraction
 Starling's law states that the greater the volume of blood entering
the heart during diastole (end-diastolic volume), the greater the
volume of blood ejected during systolic contraction (stroke volume)
and vice-versa.
