Beta-adrenergic receptor blockade has been demonstrated to reduce obstruction of the left ventricular outflow tract in patients with idiopathic hypertrophic subaortic stenosis (IHSS) and has also proved helpful in reducing angina pectoris due to ischemic heart disease. Accordingly, the effects of oral propranolol on the level and duration of exercise required to produce angina in seven patients...

Patients with significant heart disease may have entirely normal hemodynamics when assessed in the resting state during cardiac catheterization. Because most cardiac symptoms are precipitated by exertion or some other stress, however, it also may be important to assess hemodynamic performance during some form of stress such as muscular exercise, pharmacologic intervention (e.g., dobutamine infu...

Falls in older persons are an important cause of injury, disability, and death. They are also important as an indicator of decline in functional ability, requiring a careful assessment of contributing factors, in both the patient and the environment, with corrective intervention when possible. A fear of falls contributes to the problem by causing inactivity and deconditioning, further increasin...

THIS REVIEW ARTICLE RECOGNIZES THE UNIQUE FUNCTION OF THE CORE MUSCULATURE. IN MANY REAL LIFE ACTIVITIES, THESE MUSCLES ACT TO STIFFEN THE TORSO AND FUNCTION PRIMARILY TO PREVENT MOTION. THIS IS A FUNDAMENTALLY DIFFERENT FUNCTION FROM THOSE MUSCLES OF THE LIMBS, WHICH CREATE MOTION. BY STIFFENING THE TORSO, POWER GENERATED AT THE HIPS IS TRANSMITTED MORE EFFECTIVELY BY THE CORE. RECOGNIZING THI...

This demonstration will illustrate an interactive immersive computer game, POMY, designed to help Korean speakers learn English. This system allows learners to exercise their visual and aural senses, receiving a full immersion experience to increase their memory and concentration abilities to a greatest extent. In POMY, learners can have free conversations with game characters and receive corre...

BACKGROUND The long-term impact of surgical correction of congenital heart defects (CHD) on exercise capacity and quality of life (QoL) has not been well established. AIM To evaluate exercise capacity, QoL, physical activity and depression in young adult patients with a history of congenital heart defect surgery (GUCH) for simple left-to-right shunts, and to compare these parameters with thos...
