  • Title: [Cardiopulmonary exercise capacity in VVI stimulation in patients with high grade AV block].
    Author: Berge PG, Winter UJ, Ehmanns S, Hilger HH.
    Journal: Z Kardiol; 1994; 83 Suppl 3():141-4. PubMed ID: 7941661.
    Abstract:
    VVI-pacemaker patients with high-grade atrioventricular block were subjected to cardiopulmonary exercise testing. An interindividual comparison was made between patients with intermittent intrinsic rhythm (n = 9) and patients with permanent VVI-stimulation (n = 15). Patients with intermittent sinus rhythm on exercise had no significant increase in exercise capacity as quantified by the O2-uptake at the anaerobic threshold. An intermittent sinus rhythm is of no relevance to therapeutic decisions, such as choosing the appropriate pacing mode. Exercise capacity is determined by multiple, partly peripheral factors.
