The electrocardiogram (ECG or EKG) is a diagnostic tool that measures and records the electrical activity of the heart in exquisite detail. Interpretation of these details allows diagnosis of a wide range of heart conditions. These conditions can vary from minor to life threatening The term electro...
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 ...
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...
Surface ECG QRS waveform and propagation of depolarization The genesis of the QRS complex is related to the propagation of the depolarization dipole. The initial part (or vector) of the QRS complex corresponds to the depolarization to the ventricular septum. The mid part of the QRS corresponds to...
What does an ECG measure? A single round of the cardiac cycle shows up in 3 main “waves” on an ECG—the P wave, the QRS complex, and the T wave. These waves reflect the activities of the heart’s electrical conduction system, which is composed of specialized muscle fibers. ...
