Rapid and dangerously uncoordinated ventricular contractions are called?
Rapid and dangerously uncoordinated ventricular contractions is called ventricular fibrillation, or v-fib. During v-fib, the ventricle is not pumping blood to the body, and thus v-fib is known as a lethal dysrhythmia.
The peak blood pressure measured during ventricular systole is called?
Systolic Pressure
What is the lowest pressure that remains in the arterial system during ventricular relaxation?
this is called the diastolic pressure meaning when the heart is in diastole. The diastolic number is the bottom number in common blood pressure. i.e. in a pressure 120/80 the lowest measured pressure is 80mmHg during ventricular relaxation
The maximum pressure achieved during ventricular contraction is called what?
systolic pressure
Does ventricular pressure increase the fastest during ventricular filling?
yes
During ventricular systole are AV valves closed?
yes during ventricular systole AV valves are closed.
Which two valves are open during ventricular systole and closed during ventricular diastole?
The semi-lunar valves
During ventricular systole is ventricular pressure increasing or decreasing?
increasing! :D
The greatest force of the blood against the walls of the arteries during ventricular contraction is called?
That is the Systolic Pressure.
Why does tachycardia greater than 200 beats per minutes results in decreased coronary perfusion?
The heart does not have enough time between contractions to fill with enough blood to maintain adequate cardiac output. This is especially a concern because the heart itself is perfused during diastole (the period between ventricular contractions).
What AV and semilunar valve positions during ventricular diastole?
The AV valve is open and the semilunar valve is closed during ventricular diastole.
What do the two number in the blood pressure mean?
Blood pressure is pressure exerted by blood on the walls of blood vessels. The two numbers represent the systolic and diastolic pressure. Systolic pressure is the pressure exerted during ventricular contraction(also called systole) and diastolic pressure is the pressure exerted during ventricular relaxation(also called diastole). The units of blood pressure are millimeters of Mercury (mmHg) because it represents how far up a tube the pressure can push a column of mercury, which was how pressure used to be measured.
