Paroxysmal atrial flutter

Paroxysmal atrial flutter is an episodic cardiac supraventricular tachyarrhythmia characterized by sudden-onset, self-terminating bouts of rapid and regular atrial depolarizations, typically lasting from seconds up to seven days Primarily affecting the cardiovascular system in adults with underlying structural heart disease, hypertension, or pulmonary pathology, it arises from a organized macro-reentrant electrical circuit, most commonly involving the cavotricuspid isthmus in the right atrium Pa...

Paroxysmal atrial flutter is an episodic cardiac supraventricular tachyarrhythmia characterized by sudden-onset, self-terminating bouts of rapid and regular atrial depolarizations, typically lasting from seconds up to seven days

Primarily affecting the cardiovascular system in adults with underlying structural heart disease, hypertension, or pulmonary pathology, it arises from a organized macro-reentrant electrical circuit, most commonly involving the cavotricuspid isthmus in the right atrium Patients may experience recurrent, transient symptoms including palpitations, dyspnea, fatigue, presyncope, and an increased risk of thromboembolic events

Pathophysiologically, the circuit generates atrial rates typically between 240 and 340 beats per minute, which conduct to the ventricles with varying degrees of atrioventricular nodal block to produce classic "sawtooth" flutter waves on electrocardiography

Patients may experience recurrent, transient symptoms including palpitations, dyspnea, fatigue, presyncope, and an increased risk of thromboembolic events
