Initial experience with dual-sensor rate-responsive pacemakers in children.
The efficacy of a new single-chamber, rate-responsive pacemaker that utilizes information from two sensors, activity and stimulus to T wave, was evaluated in 15 children during a mean follow-up period of 10.3 +/- 3.3 months (range 5-16 months). There were 10 males and five females, with a mean age of 5.9 +/- 3.8 years (range 9 months-16 years). The indication for pacing was high grade atriovent...
متن کاملInitial experience with a physiological, rate responsive pacemaker.
A new pacemaker that can adapt the heart rate in response to the patient's metabolic requirements has been developed. This pacemaker uses the QT interval as the indicator of physiological demand. Experience in five patients showed the rate response to exercise to be smooth and progressive and to return gradually to the basic paced rate after activity stopped. Physiological rate responsive pacin...
متن کاملExperience with Devices implanted fixed-rate pacemakers.
The fate of 183 implants of Devices TF 2970 fixed-rate pacemakers is analysed. The incidence of clinical complications such as sepsis or skin necrosis, displacement of the electrode, and exit block, and the causes of the 19 deaths are discussed. In 28 of the 183 pacemakers pacing stopped for technical reasons, which are described; the commonest cause of failure was the batteries. The incidence ...
متن کاملefficacy of rate modulators in children with single-chamber pacemakers
conclusions in the children in this study, pacemaker accelerometers failed to meet physiological demands. results basal heart rates, maximal heart rates, and exercise tolerance were significantly lower in the children with pacemakers. age, sex, and body mass index had no effect on the heart rate slope during the exercise test. there was no significant difference between epicardial and endocardi...
متن کاملMonitoring equipment induced tachycardia in patients with minute ventilation rate-responsive pacemakers.
Minute ventilation-sensing pacemakers enable the paced heart to respond to an increased workload. Two patients with such a pacemaker developed pacemaker-driven tachycardia when connected to an electrocardiogram (ECG) monitor also capable of documenting ventilatory frequency and ECG lead disconnection. This tachycardia stopped when the ECG leads were removed. These pacemakers and monitors emit a...
