Why is the R wave taller than the P wave on the ECG graph cycle?
Wiki User
∙ 12y ago
The QRS complex is normally larger than the P Wave because depolarization of the larger muscle mass of the ventricles generates more voltage than does depolarization of the smaller muscle mass of the atria

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 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.
The R wave of the ECG is most closely associated with which phase of the cardiac contraction cycle?
Ventricular contraction.
What is the scientific definition of a cycle?
The scientific definition of a cycle is where a series of events occurs that affects each other event, and goes in a "cycle" and repeats. A cycle is a recurring series of successive operations or states, as in the working of an internal combustion engine, or in the alternation of an electric current or a wave.
What wave is a little shorter than bacteria?
infrared waves
How do you illustrate graph of a simple pendulum?
A sine-wave graph
A graph of frequency against the reciprocal of the wave length?
The graph is a straight line, passing through the origin, with a slope equal to the speed of the wave.
What type of wave is represented by density distance graph?

How long is a cycle in a sound wave?
A cycle in a sound wave is the time taken for one complete vibration.
Does cosine create a line on a graph?
yes cos(x) makes a wave that starts on 0,1 you will have to graph it
Is a pendulum a wave?
A pendulum moves in simple harmonic motion. If a graph of the pendulum's motion is drawn with respect with respect to time, the graph will be a sine wave. Pure tones are experienced when the eardrum moves in simple harmonic motion. In these cases "wave" refers not to the thing moving, but to the graph representing the movement.
What is follicular wave?
during the menstrual cycle, follicular wave is where the time it starts as a tertiary stage follicles to ovulation. the follicular wave consists of each cycle a women (female) goes through the menstrual cycle.
What is wave amplitude?
Wave amplitude is the displacement of the wave from equilibrium. Normally it's the distance on the graph from the crest/trough of the to y=0
What sets of data would best be shown as a bar graph?
Lets say how many people like the water slide than the wave pool. if 10 people like the wave pool and 30 people like the water slide then thats what you would put down on the bar graph.
Why cant you observe the effects of wave motion for a baseball?
Becuz a wave motion graph is 4 lamos
The length of time between a point in one cycle and the same point in the next cycle of an ac wave is the?
this is called time period of the wave. it is also the inverse of frequency of wave.
Which two wave properties can be determined from a time graph of a continuous wave as it propagrates?
period and frequency (Adaptive Curriculum)
