Presentation
We present a case of a 19-week-old fetus with atrioventricular dissociation, which spontaneously resolved. The mother had no signs of autoimmune disease. [ncbi.nlm.nih.gov]
Sometimes VT with retrograde conduction can result in AV association during VT (especially in slow VT's or when an accessory connection between ventricles and atria is present) A rare presentation of AV dissociation is called isorhythmic A-V dissociation [en.ecgpedia.org]

Non Specific ST-T Changes

The importance of differential diagnosis and treatment in atrioventricular dissociation is emphasized. [ncbi.nlm.nih.gov]

Ursodeoxycholic acid has been studied in AIH but did not provide any benefit.47 Back to Top Prognosis In patients responsive to treatment, AIH has a good prognosis. [clevelandclinicmeded.com]
In spite of its persistence and the need of a permanent pacemaker implantation, the prognosis of the disease remained good. [thieme-connect.com]
Prognosis and Treatment of Third Degree AV Block Patients with third-degree atrioventricular block (complete AV block) without pacemaker implantation have a poor prognosis, especially if they presented symptoms (syncope). [en.my-ekg.com]
The former is more likely to respond to atropine and has a better overall prognosis. Causes of complete heart block The causes are the same as for Mobitz I and Mobitz II second degree heart block. [lifeinthefastlane.com]
Etiology
Since the subject was an avid jogger, the etiology of the A-V dissociation was considered to be due to physiologically enhanced vagal tone. [ncbi.nlm.nih.gov]

The QRS complex is narrow, indicating a supraventricular etiology. P waves are present – however, they are not consistently conducting. Instead, the PR interval is changing. [ecg-interpretation.blogspot.com]
Hence, we suggest that woolly hair is a heterogenous condition and genes other than desmoplakin/plakoglobin may be involved in its etiology. Gene studies could not be carried out in our case due to economic constraints. [ijtrichology.com]

Pathophysiology
Pathophysiology The three key underlying pathophysiological mechanisms that would lead to AV dissociation are Slowing of the dominant atrial pacemaker (SA node) to an extent that would allow independent ventricular pacemaker (junctional escape rhythm [wikidoc.org]
Pathophysiology A normal cardiac impulse arises from the sinus node and is conducted through the AV junction, the bundle of His, and the bundle branches to the ventricles. [odlarmed.com]
Pathophysiology [ edit ] In the human heart the sinoatrial node is located at the top of the right atrium. [en.wikipedia.org]
Pathophysiology The proposed pathogenesis of autoimmune hepatitis involves the combination of genetic predisposition and environmental triggers. The genetic predisposition may relate to several defects in immunologic control of autoreactivity. [emedicine.medscape.com]
Prevention
After electrophysiological studies, treatment directed at suppressing AV nodal reentry prevented recurrent tachycardia. [ncbi.nlm.nih.gov]
Atrioventricular dissociation is not a primary condition in itself, but rather a symptom of an underlying dysrhythmia due to one of a number of causes that prevent the normal transmission of AV impulses: • Slowing of the dominant pacemaker (usually the [medical-dictionary.thefreedictionary.com]

The third beat is a premature junctional complex that conducts with right bundle branch block aberration, creating refractoriness in the AV node (gray area in the AV level of the ladder diagram) that prevents the next sinus impulse from conducting to [nursingcenter.com]
