Some forms are called paroxysmal atrial tachycardia (PAT) or paroxysmal supraventricular tachycardia (PSVT). Electrical signals in the heart's upper chambers fire abnormally, which interferes with electrical signals coming from the sinoatrial (SA) node --- the heart's natural pacemaker.
Atrial tachycardia is a type of atrial arrhythmia in which the heart 's electrical impulse comes from ectopic atrial pacemaker, that is to say an abnormal site in the upper chambers of the heart or atria, rather than from the SA node which is the normal site of origin of the heart's electrical activity.trial tachycardia is a type of atrial arrhythmia in which the heart 's electrical impulse comes from ectopic atrial pacemaker, that is to say an abnormal site in the upper chambers of the heart or atria, rather than from the SA node which is the normal site of origin of the heart's electrical activity.
