Presentation
Depression of the sinoatrial node secondary to tachycardia also may contribute to syncopal symptoms of patients who present with AVNRT.[16] Patients with AVNRT usually present with a heart rate within the range of 140 to 280 bpm. [ncbi.nlm.nih.gov]
"Parosmia is the perception of an unpleasant olfactory experience when an odorant is being presented," write Pierre Bonfils, MD, PhD, from the Université René Descartes in Paris, France, and colleagues. [medscape.com]
If the olfactory cortex were involved, olfactory hallucinations would be present. If the visual cortex were involved, visual hallucinations would be present, etc. Reference: Focal Status Epilepticus. [core.ecu.edu]
AVNRT occurs in 60% of patients (with a female predominance) presenting with paroxysmal SVT and it is more common in young adults. Clinical presentation AVNRT is characterized by an abrupt onset and termination of episodes. [af-ablation.org]

Brief atrial tachycardia is seen very commonly on ambulatory ECG monitoring in the elderly and is frequently asymptomatic. Symptoms of atrial tachycardia depend on the ventricular rate and the duration of the tachycardia. [healio.com]
Patients with asymptomatic pre-excitation on a 12-lead ECG are said to have a “WPW pattern.” [acc.org]

Causes of atrial tachycardia include chronic hypertension, congestive heart failure, valvular heart disease and, simply, aging of the heart. [healio.com]
AVNRT is usually well tolerated, though it can be dangerous to those with structural heart disease or a history of congestive heart failure (CHF). [alivecor.com]
The infant is often noted to be irritable, to not tolerate feedings, or to demonstrate evidence of congestive heart failure. Infants often have a history of not behaving as usual for 1 or 2 days. An intercurrent febrile illness is often observed. [rjmatthewsmd.com]

Signs and symptoms[edit] The main symptom of AVNRT is the sudden development of rapid regular palpitations.[1] These palpitations may be associated with a fluttering sensation in the neck, caused by near-simultaneous contraction of the atria and ventricles [en.wikipedia.org]

Again, the decision to pursue an ischemic workup should be based on clinical suspicion and risk factors, but in general it is not necessary. [thecardiologyadvisor.com]
AVNRT is usually well tolerated, often occurring in patients with no structural heart disease. [3] (See Prognosis, Presentation, and Workup .) Patient education Patients should be instructed on vagal maneuvers (Valsalva, diving reflex). [emedicine.medscape.com]
Workup of SVT Patients with a history of SVT should be seen by a cardiologist or even better by an electrophysiologist. The typical workup of patients with SVT involves having an echocardiogram done to search for structural heart disease. [heartracing.com]

- Premature Atrial Contractions
This arrhythmia can start suddenly after a premature atrial contraction which can be either atrial or junctional in nature. Clinically the patient can present with palpitation, shortness of breath, dizziness, and syncope. [youtube.com]
Most patients, during AVNRT, antegrade conduction occurs to the ventricle over the slow (alpha) pathway and retrograde conduction occurs over the fast (beta) pathway. (7) In most instances of AVNRT, a premature atrial contraction (PAC) is blocked in the [alivecor.com]
If a premature atrial contraction, or PAC, or less commonly a premature ventricular contraction, or PVC, occurs at the right time, the normal conduction pathway will still be refractory; thus, the action potential will conduct through the fast AV nodal [healio.com]
However, physiologically premature atrial contractions (PACs) and premature ventricular contractions (PVCs) precipitate AVNRT. [thecardiologyadvisor.com]

Prognosis
Prognosis The prognosis for patients with atrioventricular nodal reentry tachycardia (AVNRT) is usually good in the absence of structural heart disease. [emedicine.medscape.com]
Prognosis Prognosis is dependent on any underlying structural heart disease. Patients with a structurally normal heart have an excellent prognosis. In the absence of manifest pre-excitation (WPW syndrome), the risk of sudden death is very small. [patient.info]
This arrhythmia is usually stable and the prognosis is much more favorable than VT. It is usually treated with vagal maneuvers or adenosine. What does aberrancy mean? You can think of “aberrancy” as abnormal conduction. [aclsmedicaltraining.com]
IMHO, when the patient's physical and mental health is seriously affected by such bilateral parosmia, this surgery might be considered, especially when the prognosis for spontaneous recovery or effective treatment by other means is very poor. [core.ecu.edu]
Etiology
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. [icd10coded.com]
All instances of VT must be followed with an etiologic search, including EKG, ABG, chem-12, drug levels. [openanesthesia.org]
Etiology Atrioventricular nodal reentrant tachycardia (AVNRT): tachycardia caused by a dysfunctional AV node that contains two electrical pathways Atrioventricular reciprocating tachycardia (AVRT): tachycardia caused by an accessory pathway between the [amboss.com]
Etiology The substrate for atrioventricular (AV) nodal reentry tachycardia (AVNRT) is anatomic. AVNRT occurs in young, healthy patients but also in those with chronic heart disease. [emedicine.medscape.com]
The most common etiology of parosmia was URTI, which accounted for approximately 42.8% of patients. [jamanetwork.com]

Epidemiology[2] Prevalence of SVT is approximately 2 per 1,000. Incidence of PSVT is about 36 per 100,000 people per year. Women have twice the risk of men of developing PSVT. [patient.info]
Pathophysiology
Permanent junctional reciprocating tachycardia (PJRT) References:[1][3][4] Pathophysiology AVRT Do not confuse atrioventricular reentrant (or reciprocating) tachycardia (AVRT) with atrioventricular nodal reentrant tachycardia (AVNRT)! [amboss.com]
The site of interest, both from a pathophysiologic perspective (area of slow conduction contributing to the perpetuation of the macroreentrant circuit) as well as from a therapeutic perspective (target area during ablation) is the cavotricuspid isthmus [escardio.org]
Pathophysiology and types of AVNRT AVNRT is caused by a reentry circuit in or around the AV node. The circuit is formed by the creation of two pathways forming the re-entrant circuit, namely the slow and fast pathways. [litfl.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]
Prevention
After electrophysiological studies, treatment directed at suppressing AV nodel reentry prevented recurrent tachycardia. [onlinelibrary.wiley.com]
In this procedure, after administering a strong sedative or general anaesthetic, an electric shock is applied to the heart to restore a normal rhythm.[6] Arrhythmia prevention[edit] While preventative treatment may be very helpful at stopping the unpleasant [en.wikipedia.org]
