| atrioventricular nodal extrasystole | A premature beat arising from the A-V junction and leading to a simultaneous or almost simultaneous contraction of atria and ventricles. (05 Mar 2000) |
|---|---|
| auricular extrasystole | A premature contraction of the heart arising from an ectopic atrial focus. Synonym: auricular extrasystole. (05 Mar 2000) |
| A-V extrasystole | An extrasystole arising from the "junctional" tissues, either the A-V node or A-V bundle. Synonym: junctional extrasystole. (05 Mar 2000) |
| ventricular extrasystole | A premature contraction of the ventricle. Synonym: infranodal extrasystole. (05 Mar 2000) |
| return extrasystole | A form of reciprocal rhythm in which the impulse having arisen in the ventricle ascends toward the atria, but before reaching the atria is reflected back to the ventricles to produce a second ventricular contraction. (05 Mar 2000) |
| midnodal extrasystole | An obsolete term for a nodal extrasystole supposed to arise from the midportion of the A-V node and recognised in the electrocardiogram by absence of the P wave that is lost within the normal QRS complex. (05 Mar 2000) |
| supraventricular extrasystole | An extrasystole arising from a centre above the ventricle, i.e., arising from the atrium or A-V junction. (05 Mar 2000) |
| infranodal extrasystole | A premature contraction of the ventricle. Synonym: infranodal extrasystole. (05 Mar 2000) |
| interpolated extrasystole | A ventricular extrasystole which, instead of being followed by a compensatory pause, is sandwiched between two consecutive sinus cycles. (05 Mar 2000) |
| extrasystole | A premature contraction of the heart that is independent of the normal rhythm and arises in response to an impulse in some part of the heart other than the sinoatrial node. Synonym: premature beat. (18 Nov 1997) |
| upper nodal extrasystole | An obsolete term for a nodal extrasystole supposed to arise from the upper part of the A-V node; recognised in the electrocardiogram by a retrograde P wave preceding the QRS complex by an abnormally short P-R interval. (05 Mar 2000) |
| lower nodal extrasystole | An obsolete term for a nodal extrasystole supposed to arise from the lower part of the A-V node, recognised in the electrocardiogram by the retrograde P wave that follows the QRS complex. (05 Mar 2000) |
