In an EKG reading: | the P wave corresponds to the AV node firing. the QRS complex corresponds to a time when ventricular pressure is greater than atrial pressure. When in sympathetic mode, the AV Bundle will be receiving impulses at a faster rate then when in parasympathetic mode. | The T wave represents the time when the SA node first fires. The P-R interval represents the delay that occurs when the AV Bundle transmits signals to the Purkinje fibers.
