Ascites due to pacemaker syndrome.

We describe a 65-year-old man who had had a permanent cardiac pacemaker implanted in 1994 and presented now with ascites. He was investigated for 3 months without finding any cause. He was admitted with a colonic bleed due to a polyp; on cardiac evaluation he was found to have pacemaker syndrome. After adjusting the pacemaker settings his ascites and pleural effusion (which had developed later) disappeared.
