This ECG strip shows an 'Accelerated Idioventricular Rhythm'. 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. AIVR is often a clue to certain underlying conditions, like myocardial ischemia-reperfusion, digoxin toxicity, and cardiomyopathies. Accelerated idioventricular rhythm (AIVR) is a relatively benign form of ventricular tachycardia. It often occurs during reperfusion after a myocardial infarction. It has a frequency of 60-120 bpm, mostly 80-100. AIVR is considered to be a good sign, as it makes clear that reperfusion was succeeded (especially after thrombolysis). |

That is right, this is Accellerated idioventricular rhythm An accelerated idioventicular is sometimes referred to as "slow ventricular tachycardia" since it meets all criteria for ventricular tachycardia (VT), but the rate is not greater than 100, thus it is not tachicardic In Junctional rhythm the rate is 40 to 60 / min, QRS duration is normal (<0.10 sec), p waves depend on the speed of conduction :- a) Negative P waves before the QRS b) P wave after the QRS c) P wave hidden in the QRS  Junctional rhythm |
