2024年10月8日 · AIVR, also known as Accelerated Ventricular Rhythm, results when the rate of an ectopic ventricular pacemaker exceeds that of the sinus node. Often associated with increased vagal tone and decreased sympathetic tone. Note that the rate of AIVR distinguishes it from others rhythms of similar morphology:

2022年5月15日 · Idioventricular rhythm is a heart rhythm in which your lower heart chambers beat more slowly than normal. With this type of rhythm, your heart’s ventricles or lower chambers may start your heartbeat if your natural pacemaker located in the upper chambers is unable to pace the heart. Cleveland Clinic is a non-profit academic medical center.

Accelerated ventricular rhythm (idioventricular rhythm) is a rhythm with rate at 60–100 beats per minute. As in ventricular rhythm the QRS complex is wide with discordant ST-T segment and the rhythm is regular (in most cases). Idioventricular rhythm starts and terminates gradually.

2023年7月24日 · Accelerated idioventricular rhythm (AIVR) results when the rate of an ectopic ventricular pacemaker exceeds that of the sinus node with a rate of around 50 to 110 bpm and often associated with increased vagal tone and decreased sympathetic tone.

Accelerated idioventricular rhythm (AIVR) is a ventricular rhythm consisting of three or more consecutive monomorphic beats, with gradual onset and gradual termination. 1,2 AIVR is usually seen during acute myocardial infarction reperfusion (following thrombolytic therapy or percutaneous coronary intervention), and rarely manifests in patients w...

2014年11月6日 · In this study, we describe 8 adult patients with idiopathic and persistent AIVR or VT originating from the right bundle branch or the moderator band area (RBB-AIVR/VT). The clinical course, ECG characteristics, drug therapy, and …

2009年9月11日 · Accelerated idioventricular rhythm is a classical reperfusion arrhythmia while usually IVR occurs in complete heart block (complete AV block). Continuous IVR decreases cardiac output due to the lack of atrial booster function and can cause syncope or near syncope.

When the ventricular rate is between 60 and 100 bpm, it is referred to as an accelerated idioventricular rhythm. This is a hemodynamically stable rhythm that occurs commonly after myocardial...

2007年12月14日 · 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.

2022年11月10日 · This article is a guide for interpreting abnormal Idioventricular Rhythm EKGs, including qualifying criteria and a sample EKG rhythnm strip. Idioventricular rhythm is an arrhythmia originating in an ectopic site in the ventricles. These rhythms occur when the main cardiac pacemaker is not functioning or has slowed.
