UNASSIGNED: We report the case of a  82-year-old @entity1 who was admitted to our institution with acute @entity662 , @entity390 , and @entity391 . Because of @entity955 with intermittent @entity1168 , a  single-chamber pacemaker was implanted 4  years ago. The initial 12-lead ECG showed @entity955 with a  heart rate of 70   bpm, narrow QRS, and T  -wave inversions in the inferolateral leads. @entity453 was excluded by immediate cardiac catheterization. A  subsequent ECG three hours later showed a  ventricular paced rhythm. During the subsequent clinical course, @entity299 markers remained normal. However, serum amylase and lipase levels were 5  times above the normal range. According to these clinical findings, acute @entity788 was the most likely diagnosis. Abdominal ultrasound excluded pancreatic @entity39 and @entity5990 . Initial treatment consists of fasting, @entity158 control, and intravenous fluids with resolution of symptoms after a  few days. The @entity1 could be discharged 7  days later. In conclusion, the observed ECG findings in combination with @entity662 are suggestive for @entity741 mandating immediate cardiac catheterization. However, acute @entity788 might present with the aforementioned ECG changes and symptoms. The case was further complicated by a  distinct electrocardiographic memory effect due to intermittent ventricular pacing.
