Clinical reliability of single-lead VDD pacing from evaluation of P-wave sensing under dynamic conditions.
In a group of 20 patients implanted with a single-lead VDD pacing system, a wide interindividual variability was found in P-wave amplitude changes occurring under dynamic conditions, even though they were of minor clinical relevance because constant atrial tracking was maintained.
