Pacemaker-mediated tachycardia in an unconventional resynchronization device.
A 67-year-old male patient with heart failure and permanent atrial fibrillation underwent atrio-ventricular nodal ablation and a biventricular device implantation. Instead of a standard cardiac resynchronization therapy device, a DDD pacemaker was implanted with the left ventricular lead in the atrial channel. After the implant, a pacemaker-mediated tachycardia caused by T wave oversensing by t...
متن کاملTwo cases of supraventricular tachycardia after accessory pathway ablation.
Case Presentation No. 1 A 52-year-old man was referred for recurrent palpitations after 2 prior electrophysiology studies and ablations at an outside institution targeting right anteroseptal and left posterolateral accessory pathways (AP) for orthodromic reentrant tachycardia (ORT). Baseline ECG revealed sinus rhythm without preexcitation and an incomplete right bundle branch block. An ECG from...
متن کاملImaging in Cardiology: "Impossible" Pacemaker-Mediated Tachycardia during Implantation
A 78-year-old man was referred for pacemaker implantation due to symptomatic 3rd degree atrioventricular (AV) block. Neither the patient's history nor physical examination revealed abnormalities with regard to his cardiovascular status. Tachyarrhythmias such as intermittent atrial fibrillation or ventricular tachycardia had not been documented in recent years, and the patient was not on medicat...
متن کاملVentricular fibrillation triggered by a pacemaker-mediated tachycardia protection algorithm.
A 27-year-old man with complex congenital heart disease (double discordance and complete congenital atrioventricular block) previously implanted with a single-chamber pacemaker was successfully resuscitated from sudden death due to ventricular fibrillation (VF). Echocardiography showed a moderately dilated right systemic ventricle with systolic dysfunction (right ventricular ejection fraction 3...
متن کاملAtypical atrioventricular node reciprocating tachycardia masquerading as tachycardia using a left-sided accessory pathway.
OBJECTIVES The study was performed to document that atrioventricular node reciprocating tachycardia (AVNRT) can be associated with eccentric retrograde left-sided activation, masquerading as tachycardia using a left accessory pathway. BACKGROUND The eccentric retrograde left-sided activation during tachycardia is thought to be diagnostic of the presence of a left free wall accessory pathway. ...
