Why is it important to look at the time intervals of the different waveforms on a electrocardiogram?

The shape of the waveform as well as the time intervals are both important when analyzing an ECG. In essence, you are looking at what the heart is doing and how fast it is doing it. Besides the "QRS" complex, which is ventricular contractions, you normally do not need to worry about the time interval of the waveforms. What's more important is the time interval between waveforms.
By looking at the time interval between heartbeats, you can determine how fast the heart is beating. Also, the distance between certain waveforms may mean that the electrical conductivity is being slowed down or even blocked.
Keep in mind that there are multiple factors to take into account when interpreting an ECG.

When was Hello Waveforms created?
Hello Waveforms was created on 2006-02-20.
What type waveforms are produced by multivibrator?
A multivibrator produces square or rectangular waveforms.
Can you compare neurological Auditory Brainstem Response ABR waveforms recorded at different intensities for right and left ears?
Yes
What are the different signal waveforms?
The three basic waveforms are Sine, Triangle and Square waves. For transmitting, the only one that matters is the Sine wave because it has no harmonics of its own. A "harmonic" is an unwanted emanation running at an exact multiple of the frequency you're trying to use.
Why sinusoidal alternating current is chosen for electricity why not square or triangle etc?
Because this is the shape of the waveform naturally generated by a conductor that is cut by a rotating magnetic field. It would be extremely difficult, as well as unnecessary, to generate any other shaped waveforms. You should also understand that square and triangular waveforms are normally made up of sinusoidal waveforms of different amplitudes and frequencies (check out 'Fourier analysis').
What happens when magnitude of Vcc and Vee of op-amp are different?
When the magnitude of Vcc and Vee of op-amp are different the op-amp produces waveforms equal in the size of each rail.
What electronic devices produce complex wave forms Also what are the particular characteristics of the device responsible for producing the complex waveforms?
transformers and these complex waveforms produced sinusoidal signals........
Examples of timing diagram?
A timing diagram is a graph of digital waveforms showing the actual time relationship of two or more waveforms and how each waveform changes in relation to the others
