The abnormal and delayed repolarization that occurs in hypokalemia is best expressed as QU, rather than QT, prolongation, since at times it can be difficult to differentiate between notching of the T wave and T- and U- wave fusion. As the serum potassium falls, the ST-segment becomes progres...
U Wave. “U” waves are small positive deflections that may be seen following the T wave. There is no clear consensus on what they represent; however, delayed repolarization of the tissue known as papillary muscle or Purkinje fibers is often seen when present. J Wave. Osborn waves or “J...
-wide S wave in leads I and V6 -less serious than LBBB AV conduction blocks occur when electrical impulses are delayed/blocked at the ___ node AV characteristics of first degree AV block -prolonged PR interval >.2sec -all P waves are followed by QRS complexes -...

Term when would you see P on T phenomenon? Definition tachycardia moves P and T waves closer together, sometimes the T wave is superimposed on the P wave. in sinus tachy, can still distinguish P, QRS, TTerm if we have abnormal beats but theyre the same width as the other normal QRS ...
Electrical impulse is delayed traveling through the AV Node and Bundle of His QRS; depolarization or repolarization of the ventricles? Depolarization QRS; what is the configuration? negative, positive, negative QRS; time interval for a normal QRS Complex 0.06-0.11 seconds Wide QRS complex indicates ...
What is the U wave? - Focus on its presence - If present usually follows the T-wave - Almost always positively deflected and <2 mm height - Generally, represents repolarization of a small segment of the ventricle or with delayed repolarization ...
-isoelectric line from the end of the P wave to the beginning of the QRS complex-represents when the electrical impulse is traveling through the AV (atrioventricular) node, where it is delayed Premature complex An early complex that occurs when a cardiac cell or cell group other than the sino...
