title: High resolution recordings of atrial flutter.
abstract: We present high resolution tracings of atrial flutter which, to our knowledge, have not been previously described. Two patients have been studied; in both cases atrial activity was made by waves similar to each other, differing only in voltage. We discuss the nature of these waves, which are probably related to continuous atrial activity, with a segregation into small and large waveform activity. It is concluded that high resolution recordings may be valid support for the interpretation of atrial flutter activity.
