Question
Muscle cells are electrically conductive, just like neurons, but do so for the purpose of contraction. Like neurons, muscle cells maintain electrical potentials across their cell membranes, and undergo depolarization when stimulated and repolarization after contraction ends. Correctly label the parts of this diagram of a normal electrocardiogram. TOP: Select letter(s) where atrial repolarization occurs here: 1.0 QRS ST 0.5 atrial repolarization atrial depolarization -0.5 ventricular depolarization 0 200 400 600 ventricular repolarization BOTTOM: place descriptions beneath their letters Miliseconds ResetExplanation / Answer
Top: atrial repolarization occurred at ST which are normally not seen.
Bottom: P wave represents normal atrial depolarization it occurs when both left and right artia are full of blood.
QRS- Q,R and S wave together consider as QRS complex.it is the electrical forces generated by ventricular depolarization.
ST segment: it represents the time for the ventricle to pump the blood to lungs and body.
