Heart Attack/Mitral valve failure
blockage in the coronary artery due to plaque build up.
60 y/o woman w/ history of obesity and DM 2
relationship
respiration rate
respiratory sinus arrythmia (RSA)
inhale: incr. HR
exhale: decr. HR
blood pressure
circulation through the blood vessels
vital role in pumping the
blood throughout the body completely.
blood pressure goes down when heart relaxes
pulmonary circulation
increased blood pressure on the L. Atrium and veins coming from the lungs
fluid build up in lungs
urinary system
risk of kidney damage
frequent urination; incontinence.
low RBC
mitral regurgitation
high blood pressure (pulmonary hypertension)
inadequate blood flow to extremities
nervous
inadequate blood flow to brain
dysautonomia; failure of the autonomic nervous system.
concepts
cardiac output
stroke volume X heart rate = cardiac output (4.7 L)
mean arterial pressure load
average blood pressure during one cardiac cycle
stroke volume
amount of blood pumped in one sitting
preload
ventricular filling
heart rate
pulse
60-100 BPM
peripheral resistance
resistance of arteries to blood flow
afterload
the force the heart has to eject blood against
Heart sounds
Dubb;closure of aortic and pulmonary artery at the end of systole
Lubb; closure of bicuspid and tricuspid valve at the start of systole
anatomy
R/L atria and R/L ventricles
valves
Atroventricular Valve and Semilunar valve
blood vessels
arteries, veins, and capillaries
blood pathway
Right Atrium
tricuspid AV valve
Right ventricle
pulmonary SL valve
pulmmonary arteries
lungs
pulmonary veins
Left Atrium
