<p><span style="font-family: Verdana,Arial,Helvetica,sans-serif; font-size: small;"><strong>Introduction:</strong> Rate-dependent left bundle branch block is not a rare entity for the clinical practice in anesthesiology, but appears as a consequence of heart diseases or not always due to slowness in atrial frequency above all, with coronary artery diseases diagnosed only after their being ruled out. <br /> <strong>Objective:</strong> To describe the clinical-anesthetic management of a patient who presented left bundle branch block for elective thoracic surgery due to mediastinal tumor.<br /> <strong>Findings</strong>: We present a clinical case of a female patient with rate-dependent left bundle branch block who was announced for thoracic surgery, without a previous history of coronary artery disease. The surgery proceeded without complications and with positive outcome.<br /> </span><span style="font-family: Verdana,Arial,Helvetica,sans-serif; font-size: small;"><strong>Conclusions</strong>: Rate-dependent left-branch block is a rare entity and a diagnosis ruling out other cardiovascular entities or not, such as myocardial ischemia. An adequate intraoperative management of the patient provides excellent outcome without clinical translation or complications. </span></p>
