Measuring r wave amplitude
WebThe amplitude of a wave is its maximum disturbance from its undisturbed position. It is important to note that the amplitude is not the distance between the top and bottom of a wave.... WebThe speed of propagation vw is the distance the wave travels in a given time, which is one wavelength in a time of one period. In equation form, it is written as. v w = f λ. From this relationship, we see that in a medium where vw is constant, the higher the frequency, the smaller the wavelength. See Figure 13.8.

Comparing normalized R-wave distributions between the recommended ICM implant group (Group 1, n = 19) and the remaining patients (Group 2, n = 7), the proportion of ICM R-wave counts of amplitude 0. ...
WebThe R wave amplitude tends to be larger in leads V1 and V 2 at superior and leftward locations. As the site of origin shifts to the right or inferiorly, there is a trend toward lower right precordial R wave amplitude and a shift in the precordial transition zone to the left. Furthermore, R wave amplitude in lead V2 or “r” wave amplitude in ... WebThe normal U Wave: (the most neglected of the ECG waveforms) U wave amplitude is usually < 1/3 T wave amplitude in same lead.

Normal Q waves, when present, represent depolarization of the interventricular septum. For this reason, they are referred to as septal Q waves and can be appreciated in the lateral leads I, aVL, V5 and V6. Pathologic Q waves occur when the electrical signal passes through stunned or scarred heart muscle; as such, they are usually markers of previous myocardial …
