Atypical atrial flutter rarely occurs in people who have not undergone previous heart surgery or previous catheter ablation procedures. Left atrial flutter is considered atypical and is common after incomplete left atrial ablation procedures. [13] Atypical atrial flutter originating from the right atrium and heart's septum have also been described.
Type 2 or atypical atrial flutter is where a re-entrant circuit develops in either the right or left atrium, but the exact location is less clearly defined. Again though we’ve got a similar setup where a wave of activated tissue, or depolarization hits a bit of tissue in such a way that it creates a loop of depolarization that keeps going ...
Irregular "fluttering" suggests atrial fibrillation, atrial flutter, or tachycardia with variable block. [1] "pounding in the neck" or neck pulsations, often due to cannon A waves in the jugular vein. These occur when the right atrium contracts against a closed tricuspid valve. [6] Palpitations often come with other symptoms.
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 against a closed tricuspid valve leading to the pressure or atrial contraction being transmitted backwards into the venous system.

Atrial flutter is an atrial arrhythmia where the atria contract at extremely high rates as a result of a reentrant circuit. This video describes the known pathophysiology for atrial flutter, as well as the two types, signs and symptoms, complications, and treatment.
The most common complication of sinus node dysfunction is the development of tachycardia-bradycardia syndrome with abnormal atrial rhythms such as atrial tachycardia, atrial fibrillation, and flutter. [5] [3] These rhythms increases the risk of clot formation in the atrium, embolization, and stroke. [5]
Historically, the term mitral valve prolapse syndrome has been applied to MVP associated with palpitations, atypical precordial pain, dyspnea on exertion, low body mass index, and electrocardiogram abnormalities (ventricular tachycardia), syncope, low blood pressure, headaches, lightheadedness, exercise intolerance, gastrointestinal ...
This is the property of the AV node that prevents rapid conduction to the ventricle in cases of rapid atrial rhythms, such as atrial fibrillation or atrial flutter. The AV node's normal intrinsic firing rate without stimulation (such as that from the SA node) is 40–60 times/minute. [13]
