Etiology of chronic atrioventricular block in young adults in a public university hospital in India

Indian Heart J. 2021 Oct 20:S0019-4832(21)00219-4. doi: 10.1016/j.ihj.2021.09.013. Online ahead of print.ABSTRACTIn young adults, chronic atrioventricular (AV) block has scant systematic documentation in India. This prospective study included patients 18 to 40 years, presenting with AV block without reversible cause. There were 27 patients, age 32+6.3 years, with 16 males. All patients had complete AV block with a narrow QRS escape rhythm (rate 40.5±6.5 beats/min). Three patients were ANA positive and of these, 2 patients were anti ds DNA positive. The ESR and CRP levels were mildly elevated in 12 and 8 patients respectively. The rest of the tests were unremarkable. Despite performing multiple tests, the etiology remained idiopathic in most.PMID:34687748 | DOI:10.1016/j.ihj.2021.09.013
