What is valvuloplasty?
Valvuloplasty is similar to a cardiac angioplasty procedure in that it involves the placement of a balloon-tipped catheter into the heart.
Rapid potassium infusion causes diastolic or systolic cardiac arrest?
Rapid potassium infusion causes diastolic and not systolic cardiac arrest.
Phase of the cardiac cycle that shortens most in response to tachycardia?
diastolic
What are two cardiac catheterization procedures?
Balloon atrial septostomy and balloon valvuloplasty are cardiac catheterization procedures.
Coronary blood flow is greatest during what phase of the cardiac cycle?
diastolic
What part of blood pressure denotes the force exerted on the arterial walls during cardiac contraction?
The force exerted on the arterial walls during cardiac contraction is systolic blood pressure. In contrast, diastolic blood pressure is the force exerted during cardiac relaxation.
Why is there fat around the heart?
It provides protection against trauma but also lubricates the organ for its systolic (pumped) cardiac movement and for its diastolic cardiac relaxation.
Does the length of cardiac cycle decrease with more rapid heart rate?
The diastolic phase
What is the proper placement of EKG electrodes during cardiac angiography?
please display a diagram of lead placement
Coronary perfusion pressure?
the difference between aortic diastolic and right atrial diastolic pressure; a determinant of the blood flow to cardiac muscle.
What two mechanisms influence the force of cardiac contraction?
End diastolic volume and sympathetic nervous system stimulation
What is the apporiate V Code for Status post cardiac pacemaker placement?
V45.01
