Conventional and biventricular pacing in patients with first-degree atrioventricular block
EP Europace, 05/09/2012
Barold SS et al. – The duration of desynchronization after exceeding the upper rate on exercise is also more pronounced. AV junctional ablation is rarely necessary in patients with first–degree AV block but should be considered for symptomatic functional atrial undersensing or when the disturbances caused by first–degree AV block during CRT cannot be managed by programming.
