We studied exercise performance before and after conversion of atrial tachycardia to sinus rhythm, atrial bradycardia, or junctional rhythm in 10 patients 9-25 years of age 8-20 years after congenital heart disease surgery (complete transposition of the great arteries, seven of 10 patients). The same maximal cycle (five of 10 patients) or treadmill (five of 10 patients) exercise protocol was pe...

Cardiorespiratory responses to progressive exercise were examined in 38 children who had undergone heart (n = 16), heart-lung (n = 13), or double-lung (n = 9) transplantation, and in 41 healthy controls. The four groups were similar in age, but the control subjects and heart transplant recipients were significantly larger than the heart-lung and lung recipients as assessed by body mass index (B...

the emergency severity index (esi) is a five-level triage system that has shown promising reliability and validity. according to esi algorithm, in the presence of danger zone respiratory rate (rr), heart rate (hr) or oxygen (o2) saturation, patients should be up-triaged from esi level 3 to 2 hence, the current study aimed to investigate the value of the measurement of vital signs in predicting ...

Monitoring training progress during exercise training in cancer survivors: a submaximal exercise test as an alternative for a maximal exercise test? Arch Phys Med Rehabil 2010;91:351-7. Objective: To examine the use of a submaximal exercise test in detecting change in fitn...

OBJECTIVE To establish the determinants of the peak VO2 in heart transplant recipients. METHODS Patient's assessment was performed in two consecutive days. In the first day, patients performed the heart rate variability assessment followed by a cardiopulmonary exercise test. In the second day, patients performed a resting echocardiography. Heart transplant recipients were eligible if they wer...

conclusions results suggest that these methods cannot be interchanged, and vvi showed significantly lower lv peak twist, peak twisting rate and peak untwisting rate. however, when lv twist and lv twisting rates were normalized to lv length, values were comparable for both imaging techniques. results twist degree was significantly lower in the vvi group than in the tdi group (p = 0.008, r = 0.56...

Heart rate is an important vital characteristic which indicates physical and mental health status. Typically heart measurement instruments require direct contact with the skin time-consuming costly. Therefore, study of non-contact methods great importance. Based on principles photoelectric volumetric tracing, we use a computer device camera to capture facial images, accurately detect face regio...
