G. Boriani et al., CLINICAL RELIABILITY OF SINGLE-LEAD VDD PACING FROM EVALUATION OF P-WAVE SENSING UNDER DYNAMIC CONDITIONS, The American journal of cardiology, 82(5), 1998, pp. 676
In a group of 20 patients implanted with a single-lead VDD pacing syst
em, a wide interindividual variability was found in P-wave amplitude c
hanges occurring under dynamic conditions, even though they were of mi
nor clinical relevance because constant atrial tracking was maintained
