WebThe QRS complex is abnormally wide (usually 0.12 sec or more), and the T wave and QRS complex usually point in opposite directions. VPBs usually precede a sinus P wave. Occasionally, they appear just after a sinus P wave but before the normal QRS complex (see Fig. 16-7 ). WebThe pulse becomes inverted upon reflecting off the fixed end. That is, a pulse with an upward displacement will reflect off the end and return with a downward displacement. This inversion behavior will always be observed when the end of the medium is fixed.
