Comparative StudySix-minute walk test in patients with permanent cardiac pacemakers.
The 6-minute walk test (6MWT) is a simple and reliable method routinely used in the evaluation of many conditions including cardiac diseases. However, it is rarely performed in patients with pacemakers (PMs), and the applicability and safety in this group is not established. The purpose of this study was to verify the applicability and safety of the 6MWT in the evaluation of functional capacity of patients with PMs, considering the ergometry test (ET) as the criterion standard. ⋯ The 6MWT can be considered safe to assess the submaximal functional capacity and can be used as an alternative test to evaluate the results of interventions in patients with permanent cardiac PMs.

Locus of symptom limitation and exercise response to bronchodilation in chronic obstructive pulmonary disease.
To evaluate the concordance between subjective and objective indices of muscle fatigue during exercise and to assess the significance of the perception of dyspnea and leg fatigue for the exercise response to bronchodilation in chronic obstructive pulmonary disease (COPD). ⋯ Patients with COPD reporting leg fatigue as the main exercise-limiting symptom had a smaller increase in endurance time to constant work-rate exercise after bronchodilation compared with those reporting dyspnea as the main limiting symptom.

Practice GuidelineClinical Competency Guidelines for Pulmonary Rehabilitation Professionals: American Association of Cardiovascular and Pulmonary Rehabilitation Position Statement.
The article provides an outline of clinical competencies recommended for personnel providing comprehensive services in pulmonary rehabilitation (PR), complementing the American Association of Cardiovascular and Pulmonary Rehabilitation Guidelines for Pulmonary Rehabilitation Programs. Individuals wishing to provide PR services should possess a common core of professional and clinical competencies regardless of their academic discipline.

Clinical cardiopulmonary exercise testing: patient and referral characteristics.
Cardiopulmonary exercise testing (CPET) is a well-established procedure for which applications have evolved in several different medical specialties. There are limited data describing how CPET is actually used in clinical practice. Such information would be useful for understanding the clinical conditions and questions likely to be encountered by a referral laboratory, and for informing future research related to the use of CPET. ⋯ The experience of this laboratory mirrored the range of indications for CPET found in published literature. The spectrum of indications and referral sources underscore both the many causes and implications of exercise intolerance relevant to clinical practice, and the challenges to laboratory personnel for appropriate testing and reporting of data.

Randomized Controlled TrialEfficacy of pursed-lips breathing: a breathing pattern retraining strategy for dyspnea reduction.
Breathing pattern retraining is frequently used for exertional dyspnea relief in adults with moderate to severe chronic obstructive pulmonary disease. However, there is contradictory evidence to support its use. The study objective was to compare 2 programs of prolonging expiratory time (pursed-lips breathing and expiratory muscle training) on dyspnea and functional performance. ⋯ Pursed-lips breathing provided sustained improvement in exertional dyspnea and physical function.
