| cardiac pacing, artificial | Regulation of the rate of contraction of the heart muscles by an artificial pacemaker. (12 Dec 1998) |
|---|---|
| pacing catheter | A cardiac catheter with one or more electrodes at its tip which can be used to artificially pace the heart. (05 Mar 2000) |
| underdrive pacing | Electrical stimulation of the heart at a rate lower than that of an existing tachycardia; designed to capture the heart between beats, i.e., to interrupt a reentry pathway in order to terminate the tachycardia. (05 Mar 2000) |
| arrhythmias, atrial | Abnormal heart rhythm due to electrical disturbances in the atria (the upper chambers of the heart) or the AV node relay station , leading to fast heart beats. Examples of atrial arrhythmias includes atrial fibrillation, atrial flutter, and paroxysmal atrial tachycardia (PAT). (12 Dec 1998) |
| atrial | <anatomy> Pertaining to an atrium. (16 Dec 1997) |
| atrial appendage | The small projection from each atrium hanging over like a small ear, more marked on the left, with a small cavity of its own. (05 Mar 2000) |
| atrial arrhythmias | See Arrhythmias, atrial. (12 Dec 1998) |
| atrial arteries | Branches of the right and left coronary arteries distributed to the muscle of the atria. Synonym: arteriae atriales. (05 Mar 2000) |
| atrial auricle | The auricle of atrium. See: left atrium, right atrium. (05 Mar 2000) |
| atrial auricula | A small conical ("ear-shaped") pouch projecting from the upper anterior portion of each atrium of the heart, increasing slightly the atrial volume. See: auricle of left atrium, auricle of right atrium. Synonym: auricula atrialis, atrial auricle, atrial auricula, auricle, auricula, auricular appendage, auricular appendix, skin tag. (05 Mar 2000) |
| atrial bigeminy | Pairing of atrial beats, as when an atrial extrasystole is coupled to each sinus beat. (05 Mar 2000) |
| atrial branches | The atrial branches, the branches of the right coronary artery and the circumflex branch of the left coronary artery distributed to the right and left atrium, respectively. Synonym: rami atriales. (05 Mar 2000) |
| atrial capture beat | The cardiac cycle resulting when, after a period of A-V dissociation, the atria regain control of the ventricles; atrial depolarisation due to retrograde transmission from a ventricular ectopic beat or an electronically paced ventricular impulse. (05 Mar 2000) |
| atrial chaotic tachycardia | Multifocal origin of tachycardia within the atrium; often confused with atrial fibrillation during physical examination. (05 Mar 2000) |
| atrial complex | P wave in the electrocardiogram. Synonym: auricular complex. (05 Mar 2000) |
| atrial pacing |
regulation of the rate of the heartbeat by means of an intracardiac electrode inserted in the atrium or by temporary placement of an esophageal electrode.

| atrial pacing stress t. |
a stress test in which temporary immediately reversible atrial pacing is used to stress coronary reserve; used for patients incapable of exercise or in whom an exercise stress test is contraindicated.
