Atrial tachycardia is a type of heart rhythm problem in which the hearts electrical impulse comes from an ectopic pacemaker (that is, an abnormally located cardiac pacemaker) in the upper chambers (atria) of the heart, rather than from the sinoatrial node, the normal origin of the hearts electrical activity. As with any other form of tachycardia (rapid heart beat), the underlying mechanism can be either the rapid discharge of an abnormal focus, the presence of a ring of cardiac tissue that gives rise to a circle movement (reentry), or a triggered rapid rhythm due to other pathological circumstances (as would be the case with some drug toxicities, such as digoxin toxicity). Classification
Forms of atrial tachycardia (ATach) include multifocal atrial tachycardia (MAT), focal atrial tachycardia and atrial flutter. Paroxysmal atrial tachycardia (PAT) is an episode of arrhythmia that begins and ends abruptly. Etiology
Atrial tachycardia tends to occur in individuals with structural heart disease, with or without heart failure, and ischemic coronary artery disease. However, focal atrial tachycardia often occurs in healthy individuals without structural heart disease. Other possible etiologies are listed below:
Hypoxia
Pulmonary disease
Ischemic heart disease
Stimulants: cocaine, caffeine, chocolate, ephedra
Alcohol
Metabolic disturbances
Digoxin toxicity
Heightened sympathetic toneA study noted 10 to 15% of patients presenting for supraventricular tachycardia ablation had atrial tachycardia.
