RT Journal A1 Martin DC, Jr. T1 PAcemaker in cardiac vein JF JAMA JO JAMA YR 1969 FD March 24 VO 207 IS 12 SP 2284 OP 2284 DO 10.1001/jama.1969.03150250114026 UL http://dx.doi.org/10.1001/jama.1969.03150250114026 AB To the Editor:—  The report by Mullen et al of two cases of cardiac tamponade from ventricular perforation by a transvenous pacemaker (203:142, 1968) brought to mind a bizarre complication from this procedure which occurred last year at the Meadowbrook Hospital, East Meadow, NY.The patient was a 75-year-old man with chronic congestive heart failure and parkinsonism who entered the hospital with complete heart block. Preliminary management with an external pacemaker was followed one month later by subcutaneous implantation of a fixed rate pacemaker, the endocardial electrode in both instances being inserted via the right external jugular vein. Complete ventricular capture was recorded, and the rate remained at 78 to 80 beats per minute. However, increasing confusion and drowsiness were noted along with a mild, persistent azotemia. A gradual deterioration ensued, and the patient died after two months in the hospital.Autopsy showed advanced arteriosclerotic heart disease, acute bronchopneumonia
