What initiates the p wave?
cardiac cycle
Which lunar phase precedes a full moon in the lunar cycle?
The 'waxing gibbous' phase does.
Which is the phase of cardiac cycle in whitch the auricles contract?
Systole is the correct answer
What is the phase of the cardiac cycle that is caused by the sliding of actin and myosin?
Systole
What is the graphic of heart sounds produced during the cardiac cycle?
Phonocardiogram
The stage of the cardiac cycle that directly follows the resting period?
Diastole
What is the relaxing phase of the cardiac cycle?
The resting phace of the cardiac cycle is known as the refractory period
What is the period of time called between the beginning of one heartbeat and the start of the next?
Cardiac cycle
What does the term systole mean?
Systole is the period of heart contraction within the cardiac cycle.
The period of time during a cardiac cycle when contraction occurs and blood pressure rises?
systole
What portion of the cardiac cycle is shortened by this more rapid heart rate?
The ventricular relaxation period.
What is one complete heartbeat called?
The cardiac cycle.
What is the importance of cardiac cycle?
The importance of cardiac cycle is to sustain human life.
What happens in the cardiac cycle immediately before P wave?
The P wave on an ECG occurs when the sinoatrial node which is the hearts natural pacemaker fires causing the atria to contract. The period just before this when there is no electrical activity is the hearts 'resting' period between beats when the muscles are relaxed giving the atria a chance to refill with blood.
What happens immediately after the QRS wave of the cardiac cycle?
There are a number of things that may happen during the QRS wave. There will be ventricular depolarization and right after absolute refractory period for ventricles will occur.
What is a complete cycle of a heart contraction and relaxation called?
Cardiac cycle, which is made up of atrial and ventricular systole and diastole.
When do the AV valve close during the cardiac cycle?
AV valves close during the systole phase of the cardiac cycle.
