Measure t 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. WebThe ectopic P wave (called P') is often hidden in the ST-T wave of the preceding beat. (Dr. Marriott, master ECG teacher and author, likes to say: "Cherchez le P on let T" which in French means: "Search for the P on the T wave", but it's more sexy in French!) The P'R interval is normal or prolonged because the AV junction is often partially ...

WebYou need to find the J point and then measure the distance between the baseline and the J point. If that distance is more than two little blocks in the precordial leads (in other words, two millimetres) - or more than one little block in the limb leads (in other words, one millimetre) - then we say the ST segment is elevated.
