The discrete data from the MIT-BIH and the results of the measurement itself are used as the data to obtain the number of the cycle in the ECG record, the R position of each cycle, the duration of each cycle and the heart rate value. 展开 被引量: 1 年份: 2016 ...
ECG Basics Save Determining RhythmThe rhythm is either sinus rhythm or not sinus rhythm. Sinus rhythm refers to the origination of the electrical activity coming from the sinus node — also known as the sinoatrial node, or SA node. This results in an upright P wave in lead II on the ECG...
In order to determine the levels of aerobic exchange threshold, anaerobic exchange threshold, critical power and corresponding heart rate, the electrocardiography is performed in real time while the subject under examination is under the influence of physical activity, wherein notifications appear on a ...
Our aim was to identify optimal cardiopulmonary exercise testing (CPET) threshold values that distinguish disease severity progression in patients with co-existing systolic heart failure (HF) and chronic obstructive pulmonary disease (COPD), and to evaluate the impact of the cut-off determined on the...
METHOD AND DEVICE FOR TESTING A SENSOR, IN PARTICULAR A MONO-DIRECTIONAL OR BI-DIRECTIONAL ACCELERATION SENSOR OR YAW RATE SENSOR The invention relates to a method for testing a sensor (10), in particular an acceleration sensor or yaw rate sensor contained in the occupant protection system of ...
For example, heart rate has a clear reference standard (multi-lead ECG) and there are many published analytic validation studies describing the accuracy of various heart rate measurement devices39. When evaluating a novel metric where there is no clear reference standard, analytical validation becomes...
The RDI was assessed at baseline, target and final position using a portable monitor that recorded Sa,O2, heart rate, snoring sounds and body position. An off-line algorithm analysed the Sa,O2 signal to determine RDI. The monitor's diagnostic performance characteristics for OSA provided a close...
In some embodiments, a flow rate of the thermally convective fluid is less than 15 ml/min in order to maintain a desired temperature along the electrode during an ablation procedure. In some embodiments, a flow rate of the thermally convective fluid is approximately less than 10 ml/min in ...
The standard endpoint was set to be a greater than 2 mm ST-segment depression on ECG; significant side effects or arrhythmias; achievement of 85% of the age-predicted maximal heart rate; a systolic blood pressure >250 mm Hg, a significant fall in systolic blood pressure or a maximal dose ...
German patent application 197 18 806.0 to describes a device and method to determine the regularity of the heartbeat rate. The device shows a pacemaker to trigger the respiratory activity as well as a detector to measure the heartbeat rate. The device determines a behavioral regularity of the ...
