The waves or deflections shown on the ECG are named for the letters P, Q, R, S and T. R waves are the first upward deflection within a series known as the QRS complex. As part of the QRS complex, an R wave is an important indicator of cardiac health. Cardiologists and other ...

The rhythm in which ALL atrial activity is depicted as chaotic undulations of the baseline is called: A) Atrial Fibrillation. B) Atrial Flutter. C) Sinus Tachycardia. D) Atrial Tachycardia. What does the P wave of an ECG represent?
An electronic device is equipment that operates by controlling the flow of electrons or other electrically charged particles in circuits, signal processors and other semiconductor devices. Electronic devices form the basic building blocks of complex electronic systems and play an indispensable role in our...
Figure 3. An overview of the proposed heart rate and heart rate variability estimation pipeline (left to right). The face in captured webcam images is detected and modelled to track the skin pixels in the region of interest. The average value of RGB signals is extracted over time. In paral...
In short, ECG-based methods detect the R wave in the QRS complex and calculate the time between R waves (R-R interval; Fig. 1). This is what, for example, the Firstbeat Bodyguard does: it can detect the heartbeat at 1 ms accuracy (1000HZ) for very accurate HRV analysis in most pe...
What does the T wave on an ECG correspond to? What is the cardiac cycle? The events related to one heartbeat. The total amount of time if takes for one drop of blood to travel through the heart. The number of beats of the heart per minute. The events related to the flow of blood...
