This recording seems to show an atrial premature beat (3rd beat). In fact note the QT interval of the second beat is short and in fact this was an artifact from a paper jam in the EKG recorder. The EKG also shows a first degree A/V block and abnormal Q waves in the inferior and anterior leads consistent with inferior and anterior myocardial infarctions which are probably old.
