چکیده
Incremental Shuttle Walk The incremental shuttle walk was performed in an enclosed corridor on a flat 10-meterlong course. As previously described by Singh and colleagues, patients walked around two cones, each positioned 0.5 m from either end, following the rhythm dictated by the audio signal. Walking speed was initially set at 0.50 meters/second and subsequently increased by 0.17 meter/second every minute until the patient reached a symptom-limited maximum. Endurance Shuttle Walk The endurance shuttle walk was performed in an enclosed corridor on a flat 10-meterlong course, as previously described by Revill and colleagues. After a two-minute warm-up, walking speed was set at the speed corresponding to 80% of 2 O V& peak, as predicted from the incremental shuttle walk. Before each test, patients were instructed to walk for as long as possible at the speed dictated by the auditory signal. Patients were notified that no further

A 48-year-old man was admitted with exertional dyspnea. An ECG on admission revealed third-degree atrioventricular block (Figure 1). Transthoracic echocardiography demonstrated a giant mass, 6.4×6.5×7 cm, located in the basal interventricular septum (Figure 2A and 2B and Movie I in the online-only Data Supplement). The left ventricular outlet tract was mildly obstructed (Figure 2C and 2D and Mo...

متن کاملCan Help Seeking Behavior in Intelligent Tutoring Systems Be Used as Online Measure for Goal Orientation?
Questionnaires to assess goal orientation are widely used. However, recent research indicates some shortcomings. Most significantly, questionnaire data are unable to capture developments and changes in students ́ goal orientation during the learning process. Therefore, it seems appropriate to supplement questionnaire data with online measures that directly tackle students’ behavior. We analyzed ...
