At present, the only known treatment for hypertension is medication; however, the current clinical study is evaluating the efficacy and safety of a new pacemaker-based therapy. The international BACKBEAT trial involves 130 institutions worldwide and, for the time being, four institutions in Hungary, with plans to enroll a total of 316 patients.<\/p>\n<p><a href=\"https:\/\/semmelweis.hu\/english\/files\/2026\/06\/RS114967_C19A5803-scr.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignright size-medium wp-image-48307\" src=\"https:\/\/semmelweis.hu\/english\/files\/2026\/06\/RS114967_C19A5803-scr-400x267.jpg\" alt=\"\" width=\"400\" height=\"267\" srcset=\"https:\/\/semmelweis.hu\/english\/files\/2026\/06\/RS114967_C19A5803-scr-400x267.jpg 400w, https:\/\/semmelweis.hu\/english\/files\/2026\/06\/RS114967_C19A5803-scr-900x600.jpg 900w, https:\/\/semmelweis.hu\/english\/files\/2026\/06\/RS114967_C19A5803-scr-753x502.jpg 753w, https:\/\/semmelweis.hu\/english\/files\/2026\/06\/RS114967_C19A5803-scr-203x135.jpg 203w, https:\/\/semmelweis.hu\/english\/files\/2026\/06\/RS114967_C19A5803-scr.jpg 1200w\" sizes=\"auto, (max-width: 400px) 100vw, 400px\" \/><\/a>Among European institutions, the V\u00e1rosmajor Heart and Vascular Center has enrolled the highest number of patients to date <strong>\u2013 <\/strong>11 in total <strong>\u2013 <\/strong>an outstanding achievement even by international standards. \u201cThis is due to the fact that we are the largest pacemaker implantation center in Hungary.
