RIGHT ATRIAL MYXOMA
A case of right atrial myxoma in a 5 year old male is presented. The Patient was admitted in the pediatric department with systemic manifestations. Myxoma was incidentally diagnosed.
متن کاملOrganised atrial fibrillation simulating atrial flutter.
We present a case of drug-refractory paroxysmal atrial fibrillation in which episodes of AF spontaneously alternated with a regular arrhythmia resembling atrial flutter. Isthmus-dependent atrial flutter was initially diagnosed and the patient was treated with cavotricuspid isthmus ablation. Two months later the patient returned with recurrent arrhythmias. On the 12-lead ECG there was again evid...
متن کاملAtrial fibrillation and atrial flutter in athletes.
Atrial fibrillation (AF) is the most common arrhythmia in clinical practice, with an estimated prevalence of 0.4% to 1% in the general population, increasing with age to 8% in those above 80 years. The recognised risk factors for developing AF include age, structural heart disease, hypertension, diabetes mellitus or hyperthyroidism. However, the mechanisms underlying the initiation of AF in pat...
متن کامل[Differentiating between atrial flutter and atrial fibrillation using right atrial bipolar endocardial signals].
INTRODUCTION AND OBJECTIVES Contemporary atrial pacemakers incorporate pacing modes for treating atrial arrhythmias. Because atrial fibrillation in the right atrium can exhibit an organized pattern, it can be difficult to differentiate from atrial flutter. We assessed criteria for discriminating between atrial flutter and organized atrial fibrillation when using a bipolar electrode in the right...
متن کاملMapping the conversion of atrial flutter to atrial fibrillation and atrial fibrillation to atrial flutter. Insights into mechanisms.
It is not generally believed that there is a relation between atrial flutter, thought to be due to a single reentrant circuit, and atrial fibrillation, thought to be due to simultaneously circulating multiple-reentrant wave fronts. However, there are many reasons to suggest that these rhythms are more closely related than previously thought. To test the hypothesis that the length of an area of ...
