| R-R interval | The time elapsing between two consecutive R waves in the electrocardiogram. (05 Mar 2000) |
|---|---|
| P-J interval | The time elapsing from the beginning of the P wave to the end of the QRS complex (J for junction between QRS and S-T segment) in the electrocardiogram. (05 Mar 2000) |
| coupling interval | The interval, usually expressed in hundredths of a second, between a normal sinus beat and the ensuing premature beat. (05 Mar 2000) |
| P-P interval | The distance between consecutive P waves in the electrocardiogram. (05 Mar 2000) |
| P-Q interval | In the electrocardiogram, the time elapsing between the beginning of the P wave and the beginning of the next QRS complex; it corresponds to the a-c interval of the venous pulse and is normally 0.12-0.20 sec. Synonym: P-Q interval. (05 Mar 2000) |
| P-R interval | In the electrocardiogram, the time elapsing between the beginning of the P wave and the beginning of the next QRS complex; it corresponds to the a-c interval of the venous pulse and is normally 0.12-0.20 sec. Synonym: P-Q interval. (05 Mar 2000) |
| H-V interval | The time from the initial deflection of the His bundle (H) potential and the onset of ventricular activity (normally 35-45 msec). (05 Mar 2000) |
| sphygmic interval | The period in the cardiac cycle when the semilunar valves are open and blood is being ejected from the ventricles into the arterial system. Synonym: ejection period. (05 Mar 2000) |
| Sturm's interval | The distance between the anterior and posterior focal lines in a spherocylindrical lens combination. (05 Mar 2000) |
| Q-RB interval | The time between the onset of the Q wave of the QRS complex and the right bundle-branch potential (normally 15-20 msec). (05 Mar 2000) |
| Q-R interval | The time elapsing from the onset of the QRS complex to the peak of the R wave; measures the time of onset of the intrinsicoid deflection if determined in an appropriate unipolar lead tracing. (05 Mar 2000) |
| QRS interval | The duration of the QRS complex in the electrocardiogram. (05 Mar 2000) |
| Q-S2 interval | electromechanical systole |
| Q-T interval | Time from electrocardiogram Q wave to the end of the T wave corresponding to electrical systole. (05 Mar 2000) |
| interectopic interval | The distance between consecutive ectopic complexes in the electrocardiogram. (05 Mar 2000) |
