    <p>Paciente do sexo masculino, com 32 anos de idade, portador de cardiopatia chag&#225;sica, admitido em fibrila&#231;&#227;o ventricular revertida ap&#243;s sucessivas desfibrila&#231;&#245;es el&#233;tricas. Foi submetido a implante de cardiodesfibrilador dupla c&#226;mara. Retornou assintom&#225;tico trinta dias ap&#243;s a alta. O teste de limiar evidenciou aus&#234;ncia de captura atrioventricular com m&#225;xima energia. O exame f&#237;sico revelou irregularidades sobre o gerador, sugerindo deslocamento dos eletrodos (<xref ref-type="fig" rid="fig01">fig. 1</xref>). A fluoroscopia do t&#243;rax demonstrou o desposicionamento dos cabos eletrodos, ambos agrupados ao redor do gerador (<xref ref-type="fig" rid="fig02">fig. 2</xref>). A rota&#231;&#227;o do gerador, espont&#226;nea ou provocada, que resulta em desposicionamento de cabo eletrodo, perda de captura ou estimula&#231;&#227;o diafragm&#225;tica, &#233; conhecida como s&#237;ndrome de <italic>twiddler</italic>.</p>

      <p>A male 32 year old patient with Chagas&#146;s cardiopathy was admitted presenting with ventricular fibrillation reverted after successive electrical defibrillation maneuvers. He was submitted to dual chamber cardioverter defibrillator implantation, and returned asymptomatic thirty days after hospital discharge. The threshold test showed absence of atrioventricular capture with maximum pulse energy. Physical examination revealed irregularities over the generator suggesting displacement of the electrodes (<xref ref-type="fig" rid="fig01-body2">fig. 1</xref>). Chest fluoroscopy showed dislodgement of the leads, both grouped around the generator (<xref ref-type="fig" rid="fig02-body2">fig. 2</xref>). Rotation of the generator, whether inadvertent or deliberate, resulting in the dislodgement of the electrodes, loss of capture or diaphragmatic stimulation is known as Twiddler Syndrome.</p>
