Abstract
Two cases of audible atrial sounds occurring during atrial flutter-fibrillation are reported. In the first case, the atrial sounds were recorded at roughly half the rate of the atrial flutter-fibrillation waves; this is in contrast to the usual 1:1 relation of all previously reported cases of atrial flutter. In the second case, the atrial sounds increased abruptly in intensity during ventricular systole and early diastole up to the opening snap. It is suggested that the atrial sounds in the present cases were produced by a rapid tensing of the atrial wall during atrial contraction. Such audible atrial activity is probably more common than is generally appreciated.
