Pacing in vasovagal syncope: physiology, pacemaker sensors and recent clinical trials—Precise patient selection and measurable benefit. Heart Rhythm. 2020; 17: 821-828 Abstract Full Text Full Text PDF Scopus (14) Google Scholar present an excellent review on use of the pacemaker (PM) for treatment of neurocardiogenic syncope (NCS). It is a detailed approach of great value for updating electrophysiologists, cardiologists, and neurologists on the topic. The results of the main randomized trials of PM for NCS are accurately discussed. Pacing in vasovagal syncope: Physiology, pacemaker sensors, and recent clinical trials—Precise patient selection and measurable benefitHeart RhythmVol. 17Issue 5PreviewThe role of pacing in vasovagal syncope (VVS) is considered from a physiological basis. Most VVS patients lose consciousness due to hypotension before severe bradycardia/asystole occurs. Patients who benefit from dual-chamber pacing typically are older with highly symptomatic, late-onset, frequent and severe syncope with short/no prodrome and documented severe cardioinhibition. Tilt testing is of value in patients with recurrent unexplained syncope to identify important hypotensive susceptibility stemming from reduced venous return and stroke volume (SV). Full-Text PDF
