- Palpitations
The indications of electrophysiology study were nonspecific palpitation (n = 5), unexplained syncope (n = 6), postablation of accessory pathways (n = 4), and postmodification of AV nodal reentry tachycardia (n = 2). [ncbi.nlm.nih.gov]
Holter monitoring was performed in patients complaining of palpitations. Statistical analysis Data are presented as mean ± SD, median (25th; 75th percentiles) and proportions (percentages). [academic.oup.com]

Workup
In the last two years, I seem to be in a junctional rhythm constantly, sometimes with sinus rhythm as well….Seen several MDs and had a fairly comprehensive workup in last several years including normal echo, CMRI, and Holter/Event studies showed nothing [texasheart.org]
Treatment
Cardiac Arrhythmias is a long-established and widely respected guide to the interpretation and treatment of cardiac rhythm disorders. [books.google.com]
Treatment 1. No treatment if asymptomatic 2. Treatment is directed toward the underlying cause 3. Cause may be unrecognized XI. Nonconducted PAC A. [andrews.edu]
Generally there is no treatment needed in individuals who are asymptomatic except observation. For those with symptoms, identify and treat the cause. [learningcentral.health.unm.edu]
If you are found to have this irregular rhythm, see treatment with a cardiologist for an evaluation. [newhealthadvisor.com]

Prognosis
Prognosis of Atrioventricular Conduction Block The prognosis of patients with AV conduction disturbances depends on the site of the block, but also particularly on the concomitant or underlying heart disease. [revespcardiol.org]
CASES of double tachycardia (DT) have been infrequently reported. 1 2 3 4 The association with digitalis toxicity and a poor prognosis are known. [nejm.org]
Prognosis No evidence suggests increased mortality. Prognosis is good. Morbidity/mortality The heart rate during a junctional rhythm often determines whether the patient has symptoms. [emedicine.com]
Some people may have trouble with: Bradycardia (slow heart rate) Dizziness Fainting Need for pacemaker Shortness of breath Injuries from fainting Worsening of heart conditions (Congestive Heart Failure, Cardiac Ischemia) The prognosis for accelerated [newhealthadvisor.com]

Pathophysiology The junctional rhythm initiates within the AV nodal tissue. Accelerated junctional rhythm is a result of enhanced automaticity of the AVN that supersedes the sinus node rate. [emedicine.com]
Pathophysiology The AV node in these patients behaves functionally as if there were two separate pathways through the node. The two pathways (alfa and beta pathways ) are differentiated by their characteristic electophysiologic pr operties. [af-ablation.org]
