[Cases of paroxysmal atrial fibrillation]

By examining carefully 516 cases of atrial fibrillation and in particular of 144 paroxysmal atrial fibrillation, the Author draws considerations on pathogenesis of paroxysmal atrial fibrillation, on the most important clinical notes, on prognosis and treatment. He also suggests to define the typical paroxysmal forms which to his opinion are different from those he prefers to call "unstable fibrillation".
