An R wave is an upward deflection displayed on an electrocardiogram (ECG). During an electrocardiogram, the heart’s rhythm is recorded on graph paper via electrodes attached to the skin. The waves or deflections shown on the ECG are named for the letters P, Q, R, S and T. R waves ...
Method for identifying a characteristic profile of an R-wave in an EKG signal and a computer program product as well as an electronically readable data medium for performing the method, United States Patent application publication. 2011. Pub No: US 2011/ 10319780 A1; http://appft1.uspto.gov/...
Batches of 30s each of EKG lead II waveforms were recorded during surgical procedures with mechanical ventilation. R wave amplitude variability was assessed both manually and by automated algorithm. For both calculations, wave height was defined as R wave peak minus preceding Q wave trough, and ...
The present invention uses a R-wave sensing algorithm that uniquely combines an automatic threshold adjustment method with a new noise rejection technique. This algorithm has significant advantages in avoiding the sensing of T-waves, P-waves, and noise/artifacts. Detecting the presence of noise burst...
What is the EKG? Explain the following waves and intervals: P-wave, P-R interval, QRS wave, S-T segment, QT interval and T wave. Heart: The heart has the right as well as left chambers that are detached by a wall. It is a k...

Background: Studies have shown that respiratory variation in the EKG lead II R-wave amplitude (EKGv) correlates with dynamic predictors such as pulse pressure variation (PPV) and stroke volume variation (SVV) in mechanically ventilated patients under general anesthesia1 and to predict volume status...
