Implantable loop recorder is an effective diagnostic tool for identifying the cause of unexplained syncope, leading to pacemaker implantation for treatment of bradyarrhythmias associated with syncope.

An implantable loop recorder successfully identified a 45-second pause as the cause of unexplained syncope in a 60-year-old man, enabling targeted treatment with a pacemaker.

Male patient, 60 years old, is referred for the first time to Pacemaker Center Zajecar on 26th of July 2018. for assessment of possible indication for pacemaker implantation. After initial evaluation (History, Clinical exam and ECG) with normal findings patient hade Additional evaluation for syncope. He has done a three 24-hour Holter recordings with no significant disturbances in excitability or conductivity. Sinus bradycardia was found during sleep. During the day hours, a chronotropic competence is maintained. Exercise test that he has also done is described as negative for ischemic disease, with preserved chronotropic competence. Echocardiography described like normal finding.Neurological exams: clinical finding is normal. MRI of the head was done, also with normal findings. The patient was implanted with implantable loop recorder in left pectoral region, the device was Medtronic Reveal LinQ. During regular device electronic check up we found a several pauses detection of which the longest was 45s in duration. Based on these recordings, an indication for pacemaker implantation was made.Conclusions: Cardiac syncope represents a clinical and diagnostic challenge. An implantable loop recorder is an adequate diagnostic tool for cardiac syncope detection in patients with syncope of unknown origin. Pacemaker implantation is a permanent solution for treatment of cardiac syncope caused by bradyarrhythmia events.
Mitov et al. (Tue,) conducted a case report in unexplained syncope (n=1). implantable loop recorder was evaluated on Detection of syncope caused by bradyarrhythmia (N/A, 95% CI N/A, p=N/A). Implantable loop recorder is an effective diagnostic tool for identifying the cause of unexplained syncope, leading to pacemaker implantation for treatment of bradyarrhythmias associated with syncope.
