What is IVR rhythm?

Accelerated idioventricular rhythm is a ventricular rhythm with a rate of between 40 and 120 beats per minute. Idioventricular means “relating to or affecting the cardiac ventricle alone” and refers to any ectopic ventricular arrhythmia.

Accordingly, what’s Idioventricular rhythm?

Definition and Causes. I. Idioventricular rhythm is characterized by a ventricular rate that is slow or comparable to a normal sinus rate (60 to 150 bpm in the dog, >100 bpm in cats).

One may also ask, is AIVR dangerous? AIVR is generally a transient rhythm, rarely causing hemodynamic instability and rarely requiring treatment. However, misdiagnosis of AIVR as slow ventricular tachycardia or complete heart block can lead to inappropriate therapies with potential complications.

Hereof, how do you treat Idioventricular rhythm?

Under these situations, atropine can be used to increase the underlying sinus rate to inhibit AIVR. Other treatments for AIVR, which include isoproterenol, verapamil, antiarrhythmic drugs such as lidocaine and amiodarone, and atrial overdriving pacing are only occasionally used today.

What does AIVR stand for?

Accelerated Idioventricular Rhythm (AIVR) is a ventricular rhythm consisting of three or more consecutive monomorphic beats, with gradual onset and gradual termination. It can rarely manifest in patients with completely normal hearts or with structural heart disease.
