Sine-wave speech can be thought of as a sort of auditory illusion, a sensory edge case in which one’s experience has a clear “before” and “after” moment, like going through a one-way door.

pathological Q-waves, left axis deviation and conduction delays and findings suggestive or diagnostic of primary electrical diseases such as long QT syndrome and Wolff-Parkinson-White syndrome. The ...

These ECG voltage attenuations are of extracardiac mechanism, and impact the amplitude of QRS complexes, P-waves, and T-waves, occasionally resulting also in shortening of the QRS complex and QT ...

Suppose a medical technician is measuring a 5 Hz EKG sine wave signal from a patient. The measuring device, however, picks up instrument noise of 50 Hz, so that the actual measured signal is a mix of ...

In its simplest form it involves a sine wave carrier whose instantaneous frequency is varied, i.e. modulated, according to the waveform (assumed here to be another sine wave) of the so-called ...

From its 1 Hz lower end to its 65.5 kHz upper end, the sine wave shape remains the same and ... and unexpectedly, an ECG waveform that looks super realistic at 1 Hz with a 200 mS timebase.

These lines are comprised of three main parts: In normal sinus rhythm, the P-P interval (the time between consecutive P waves ...

Electrocardiography (ECG) is a transthoracic (across the thorax or chest) interpretation of the electrical activity of the heart over a period of time, as detected by electrodes attached to the ...

Fourteen studies and two case series were found describing ST-segment abnormalities and/or significant Q-waves in association ... drug exposure to first noted electrocardiogram abnormality or ...

—A new study shows that SCD is linked to prolonged P-wave duration, even in individuals with no coincident cardiovascular conditions or atrial fibrillation. Share on Facebook. Opens in a new tab ...
