Regulation of Heart Rate
Hemodynamics
100
A lack of sufficient (oxgenated) blood flow to a body part due to obstructionor constriction of a blood vessel
What is ischemia
100
The plateu phase of Action Potential that allows cardiac muscle to sustain an increased period of contraction
What is Phase 2
100
Ability of myocardial cells to shorten causing cardiac muscle contraction in response to electrical stimulus
What is Contractility
100
Alternating compression and decompression of veins during inhalaton ahd exhalation
What is the Respiratory Pump
200
Abnormal narrowing of an orifice such as a heart valve
What is Stenosis
200
Is the layer of the heart muscle responsible for the pumping action of the heart
What is Myocardium
200
starts when threashold becomes -70 mV
What is Membrane Potenial
200
Refers to a change in heart rate
What is the chronotropic effect
200
velocity is slowest in the cardiovascular system
What is capillaries
300
Thickening of the myocardium associated with certain heart diseases
What is Hypertrophy
300
Carries blood from the head and upper extremities to the Right Atrium
What is Superior Vena Cava
300
The cell is at Resting Membrane Potiental and K+leaking out of the cell
What is Phase 4
300
The Parasympathetic cholinergic receptors
What is Nicotinic and Muscarinic
300
Normal PCWP measurement
What is 4-12 mmHg
400
A wasting away of muscle size and tone with prolonged disuse
What is atrophy
400
A chamber that recieves oxygenated blood from teh lungs through the pulmonary veins
What is Left Atrium
400
The refractory period when cell will not respond to further stimulation within itself
What is Absolute Refractory Period (ARP)
400
Slows the conduction of through the AV node
What is Negative (cholinergic) Dromotropic
400
Represents the closing of the aortic valve on an arterial line
What is Dicrotic notch
500
Inner layer of the serous pericardium that adhers to the outside of the heart
What is Visceral Pericardium
500
Four veins that carry oxygen rich blood from the lungs to the heart
What is Pulmonary Veins
500
The point in time when a weaker than normal stimulaus can cause cardiac cells to depolarized during this period
What is Supranormal Period
500
Detect change in blood pressure
