What are the characteristic of a wave?
in general, a harmonically oscillating, one dimensional wave is described by the following function: f(x,t)=Acos(2phi*t/T -2phi*x/ג) where A is the amplitudes (or wave height), T is the wave's period time and ג is the wave length. these are the three basic characteristics of a wave. other characteristics can be calculated from these: the frequency f=1/T , and the speed of the wave v=גf.
Give an example of the other type of wave.?
The PR wave,QRS wave, and T wave.
What best describes why refraction of a wave occurs when the wave travels from one material into another?
Refraction occurs because the speed of the wave varies in different materials,sin(I)/V(I) = sin(T)/V(T)
How do you measure the frequency of a sound wave?
Capture the sound with a microphone, feed its output into an oscilloscope with a calibrated timebase. Measure the time period T of the wave on the horizontal axis, then convert it into a frequency ( = 1/T)
What is the wavelength of the wave?
The distance from one peak to the next peak
What is r t segment?
The R-T segment is the portion of the EKG tracing from the R wave to the T wave.
What is a T-wave?
The T wave represents the repolarization (or recovery) of the ventricles. The interval from the beginning of the QRS complex to the apex of the T wave is referred to as the absolute refractory period. The last half of the T wave is referred to as the relative refractory period (or vulnerable period). The T wave contains more information then the QT interval. The T wave can be described by its symmetry, skewness, slope of ascending and descending limbs, amplitude and subintervals like the TpeakTend interval. In most leads, the T wave is positive. However, a negative T wave is normal in lead aVR. Lead V1 may have a positive, negative, or biphasic T wave. In addition, it is not uncommon to have an isolated negative T wave in lead 3, aVL, or aVF.

The period during which the ventricles are repolarizing?
the asnwer is t wave
Give an example of the other type of wave.?
The PR wave,QRS wave, and T wave.
What is the portion of the ECG that indicates ventricular repolarization?
The wave indicating atrial repolarization wave is hidden by the QRS complex. Ventricular repolarization is indicated by the T wave.
How do wave frequency and period of a wave relate?
Wave frequency f, and period of wave T are inverses, related by fT=1.
What does abnormal t wave mean?
what causes abnormal t waves
Why is the T wave positive in the ECG?
The T wave is positive in an ECG due to the direction and charge. This positive deflection occurs after each QRS complex.
What happens during the t wave in the heart?
During the T-wave the ventricles are repolarizing, preparing for the next beat.
What does a inverted QRS wave indicate?
In QRS wave, P wave shows atrial contraction or depolarisation whereas, T wave shows ventricular repolarisation.
How does hyperkalemia relate to the ECG?
Hyperkalemia cause tall t wave and wide qrs wave
