Key result
In a prospective study of 27 young adults with chronic atrioventricular block in India, the etiology remained idiopathic in most patients despite multiple tests.
Why the study?
Chronic atrioventricular block in young adults has scant systematic documentation in India.
What is the etiology of chronic atrioventricular block in young adults presenting without a reversible cause?
Observational (n=27)
No
What is the etiology of chronic atrioventricular block in young adults presenting without a reversible cause?
In young adults in India presenting with chronic AV block without a reversible cause, the etiology remains largely idiopathic despite extensive testing.
May support autoimmune evaluation in young Indians with unexplained AV block; leaves open larger studies before changing practice.
In young adults, chronic atrioventricular (AV) block has scant systematic documentation in India. This prospective study included patients 18-40 years old, presenting with AV block without a reversible cause. There were 27 patients, aged 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.

Chavan et al. (2021) conducted an observational in Chronic atrioventricular block (n=27). Chronic atrioventricular block was evaluated on Etiology of chronic AV block. In a prospective study of 27 young adults with chronic atrioventricular block in India, the etiology remained idiopathic in most patients despite multiple tests.
