RF energy (30\u201340\u2005W, \u226490\u2005s) at the LV anterior wall markedly suppressed ectopy, followed by abrupt chest discomfort and hypotension. Fluoroscopy suggested pericardial effusion; emergent pericardiocentesis yielded 150\u2005ml of bright red, arterialized blood with rapid hemodynamic recovery. Biventricular angiography showed no contrast extravasation, and serial echocardiography confirmed no recurrent effusion. The patient stabilized with indwelling drainage and was discharged uneventfully.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Tamponade during LV ablation may occur without overt perforation.
