Preserved exercise capacity possible via compensation in congenital AV block; leaves open generalizability beyond case reports.
What are the electrocardiographic and hemodynamic responses to graded exercise in patients with congenital complete atrioventricular block?
Patients with congenital complete AV block can maintain normal or near-normal physical working capacity during exercise through compensatory hemodynamic mechanisms.
IKKOS et al. (1960) studied this question.
