EKG terms
EKG terms | Answer |
---|---|
P wave | produced when signal from SA node spreads through ATRIA and DEPOLARIZES them. Atria systole begins after P wave in P-Q segment |
QRS complex | marks firing of AV node and onset of VENTRICULAR DEPOLARIZATION |
T-wave | generated by VENTRICULAR REPOLARIZATION immediately before ventricular diastole |
PQ segment | atrial systole |
ST segment | ventricular systole |
What repolarization takes place in QRS? | atrial repolarization |
mechanical event (muscle contraction) | follows electrical event (action potential) |
