What initiates the p wave?
cardiac cycle
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
What is the stage of the cardiac cycle which precedes the resting period?
atrial systole <---- might be wrong
What initiates the p wave?
cardiac cycle
Is the p wave part of the cardiac cycle?
Yes - On an ECG the P wave is the first wave of the cardiac cycle. It represents the Sinoatrial node which is the natural pacemaker of the heart firing and causing the atria to contract in order to fill the ventricles.
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.
How does the P wave the qrs complex and t wave relate to the electrical and mechanical evemts of the cardiac cycle?
its related to the dialysis
The R wave of the ECG is most closely associated with which phase of the cardiac contraction cycle?
Ventricular contraction.
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 after the p wave?
The T wave on an ECG reading is the last wave in the cycle, and it represents the repolarisation of the heart. This means that the ventricles have just contracted sending blood around the body, and the heart is now 'resetting' itself ready for the next cycle.
What is the period of time called between the beginning of one heartbeat and the start of the next?
Cardiac cycle
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.
What is the speed of a wave whose wavelength is 5 cycle and whose frequency is 5Hz?
I've got no idea what a "5 cycle wavelength" is. However, I would just apply this formula: v = fλ, where v is the velocity (speed in m/s) of the wave, f is the frequency (in hertz), and λ is the wavelength (in m).
When do the AV valve close during the cardiac cycle?
AV valves close during the systole phase of the cardiac cycle.
