The pacing indications included atrioventricular block and sinus node dysfunction. The mean left ventricular activation time was 75 \u00b1 8 ms. At a median follow\u2010up of 6 weeks, pacing parameters remained stable with no evidence of lead displacement, haematoma, or infection. There were no immediate procedural complications.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>LBBP appears to be a feasible and safe physiological pacing strategy in nonagenarians with symptomatic bradycardia.
