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) |
