Atrial 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 کاملFrequency of cerebral infarction in patients with inherited neuromuscular diseases.
We evaluated the frequency of cerebral infarction in 131 patients with Duchenne's muscular dystrophy, myotonic dystrophy, Becker's muscular dystrophy, or Friedreich's ataxia. Electrocardiographic abnormalities were found in 83% of patients with Duchenne's muscular dystrophy, 56% with myotonic dystrophy, 50% with Becker's muscular dystrophy, and 25% with Friedreich's ataxia. Atrial flutter occur...
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 ...
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 کاملMyotonic Dystrophy Initially Presenting as Tachycardiomyopathy Successful Catheter Ablation of Atrial Flutter
Myotonic dystrophy is a genetic muscular disease that is frequently associated with cardiac arrhythmias. Bradyarrhythmias, such as sinus bradycardia and atrioventricular block, are more common than tachyarrhythmias. Rarely, previously undiagnosed patients with myotonic dystrophy initially present with a tachyarrhythmia. We describe the case of a 14-year-old boy, who was admitted to the hospital...
