WebJan 10, 2024 · An R wave is the first positive deflection from baseline. An S wave is a negative deflection that follows an R wave. When a complex is all positive, it is just an R wave; when it is all negative, it is called a QS. Regardless of the shape of the complex, ventricular depolarization waves are called QRS complexes ( Fig. 15-3 ). WebP waves are the first waveform in the complete complex, normally found upright in most leads. They represent the depolarization of both the right and left atria, which occur at the same time.

WebJul 17, 2024 · The first positive deflection is upward and is called as “P.” Then the first downward deflection is termed as “Q.” A second upward deflection is called “R” wave. Many times it is not preceded by “Q.” Any deflection below the baseline following “R” is called as “S” wave. After this any positive or negative deflection is called as “T” wave. WebFeb 11, 2013 · A positive deflection in an EKG tracing represents electrical activity moving toward the active lead (the green lead in this experiment). ...
