title: Pacemaker twiddler's syndrome: a note on its mechanism.
abstract: Two elderly women were given a bipolar endocardial ventricular inhibited demand pacing system. They developed total loss of capture on the 16th and 62nd post-operative day and sikagrams of chest revealed pull out of endocardial catheter due to formation of multi-twined loop in the loose and laxed subcutaneous pulse generator pockets. Various mechanisms of this unusual complication with suggestions for prevention have been discussed.
