Terms Related to Ectopic Atrial Tachycardia

• AV Nodal Reentrant Tachycardia

  A tachycardia characterized by rates between 150 and 250 beats per minute and a QRS complex of supraventricular origin.

• SA Nodal Reentrant Tachycardia

  A tachycardia arising from the sinus node region and characterized by rates between 115 and 140 beats per minute. It is paroxysmal rather than constant.

• Junctional Ectopic Tachycardia

  A tachycardia arising in the conduction tissues surrounding the atrioventricular node. It usually occurs during myocardial infarction, after heart surgery, or in digitalis intoxication. The ...

• Atrial Ectopic Beat

  Premature contractions of the heart arising from an ectopic atrial focus. With ventricular premature complexes, they represent one of the most common causes of irregular ...

• Torsades de Pointe

  A ventricular tachycardia characterized by periodic twisting of the points of the QRS complexes and rates between 200 and 250 beats per minute. It may ...

• Atrial Extrasystole

  Premature contractions of the heart arising from an ectopic atrial focus. With ventricular premature complexes, they represent one of the most common causes of irregular ...

• Atrial Fibrillation
