On this occasion the pulse remained slow for about four hours after the attacks. From November the loth to February the 17th the pulse was taken every hour in order to note any variation in rate and rhythm. Tracings taken on several occasions showed that the intermissions were due to dropped ventricular beats occasioned by impairment of conduction from auricle to ventricle and that the irregularity was due.to auricular fibrillation.The following is a summary of the dates and duration of the variations noted as intermittent or irregular.
