Fastest action potential in the heart is through these fibers.
These cells set the heart rate at 25-40 beats/min if the AV node fails
The ST interval reads zero in EKG because all the cells are ___________.
What type of Calcium channel is open in the upstroke of Pacemaker action potential?
Calcium ATPase is the _______active transporter of Calcium out of the cell.
Increase in the amount of these channels increases the rate of depolarization.
This organ extracts the most oxygen.
What channel is open in the upstroke of action potential of conducting and contracting cells?
Autonomic control that decreases heart rate and conduction.
The only way for a signal to get from atrium to ventricles is through this.
These valves shut at the beginning of Diastole. S2.
Systole or Diastole: Isovolumic contraction, Ventricular Ejection
Autonomic control that increases heart rate, conduction, and contractility.
What interval is the time between atrial depolarization and ventricular depolarization.
This channel in the pacemaker action potential opens when the membrane becomes more negative and does not inactivate.
There is a decrease in __________ in heart failure.
An increase in _________ is a compensation for heart failure where the systolic function curve shifts back to the left.
This organ gets the most flow per gram tissue because it is a filtration system.
In neurons, the first cell to depolarize is the ______ cell to repolarize.
This node sets the heart rate at 40-55 beats/min if the SA node fails.
This organ has blood flow that is in series with all other organs.
Preload or Afterload: Pressure that the ventricles need to have in order to eject blood.
Name an electrical event that is not detected on an EKG.
Aortic ______ is when the aorta narrows and ventricles have to generate pressure that is larger than normal.
Change in Pressure = Flow * _________
xxxx
These organs have capillary beds that are in series.
This neurotransmitter is released by PNS and increases the number of K+ channels.
a, c or v wave: atria contracting and pushing blood into the ventricles.
The long action potential in cardiac muscle prevents the summation of twitches called ___________.
This type of muscle has a plug on SR that is taken out when Calcium binds to the T-tubule membrane.
Bundle of His, Bundle Branches, and Purkinje System are _________ cells.
a, c or v wave: ventricles contract and push back on the AV valve.
The right and left side of the heart are two pumps in ___________.
________ Recoil prevents aortic pressure from falling.
What type of Calcium channel is open in the slow depolarization of the Pacemaker action potential?
Slowest action potential in the heart is through these modified cardiac myocytes.
What interval is the time between ventricular depolarization and ventricular repolarization?
These valves shut at the beginning of Systole. S1.
Autonomic control that acts on nodal cells, ventricular muscles, and smooth muscles surrounding blood vessels.
Amount of blood ejected by the ventricles.
Systole or Diastole: Isovolumic relaxation, Filling of Ventricles, Atrial Contraction
This node sets the heart rate at 60-100 beats per minute.
Velocity of Blood Flow = Flow / ______
In heart cells, the last cell to depolarize is the ______ cell to repolarize.
Autonomic control that innervates only nodal cells and only controls heart rate. It does it through acetylcholine binding to muscarinic receptors.
Aortic ______ is when the valve does not shut properly and the pressure drop is faster and more significant.
An increase in _________ is a compensation for heart failure where sympathetic stimulation of veins push more blood back to the heart.
Counting the boxes between R waves, multiplying by 0.04s, taking an inverse, and multiplying by 60 is way to calculate ______ from an EKG.
a, c or v wave: passive filling of atria because the AV valve is closed.
An increase in Reynolds number results in increased chance of ________ flow.
