A more flexible acquisition scheme could optimise acquisition parameters specifically for each patient and heart rate with potential improvements in image quality or temporal resolution. The aim of this study was to assess the feasibility of a perfusion pulse sequence which adapts to the heart rate, ...
On standard electrocardiogram (ECG) PQ interval is known to be moderately heart rate dependent, but no physiologic details of this dependency have been established. At the same time, PQ dynamics is a clear candidate for non-invasive assessment of atrial abnormalities including the risk of atrial ...
(VPCs) were analyzed using a computerized system, designed to evaluate the relationships between 1) the VPC frequency and heart rate (HR) (VPC-HR relation), 2) the coupling interval (CI) of VPCs and HR (CI-HR relation), and 3) the incidence of ventricular tachycardia (VT) and HR (VT...
OBJECTIVES: The purpose of this study was to determine whether the type of training in a young population differentiates heart rate variability parameters between athlete groups and sedentary subjects. METHODS: The effect of different types of physical training on heart rate variability was evaluated in...
Maximal rate of heart rate (HR) increase (rHRI) as a measure of HR acceleration during the transition from rest to exercise, or during an increase in workload, tracks exercise performance. rHRI assessed at relative rather than absolute workloads may track performance better, and a field test...
The audio files are sampled at a constant rate of 22050 Hz. The shorter audio files are padded with zeros to match the length of the longest audio file at 12 seconds. The lables are one-hot encoded.labels = { 'murmur' : np.array([1,0,0,0]), 'normal' : np.array([0,1,0,0]...
