Question

- Indicate each statement given below as true or false

( ) While the bipolar lead measurements includes Lead I, Lead II and Lead III, the unipolar lead measurement includes aVR, aVL, and aVF.

( ) Time from the onset of atrial depolarization to the onset of ventricular depolarization represent with P-R Segment.

(   ) Different from ECG, EMG signal is formed by irregular waveforms.

( ) Voluntary fixation involves subconscious mechanisms that operate to keep the selected object in your field of view once you have locked on to it.

( ) In general, EEGs can be divided into four types of waveform according to its voltage range.

( ) In the EEG recording, available locations for positioning electrodes are the frontal, parietal, temporal, and occipital lobes of the brain.

( ) In a normal respiratory, diaphragm contracts regularly and will be pulled down.

( ) While temperature is highest in the inspiration part of the respiratory cycle, temperature is lowest in the expiration part of the respiratory

( ) In AC measurement for EDA recordings; if effective voltage is kept constant in AC measurement, EDA is recorded directly as skin admittance (SY), while the appliance of constant effective current result in skin impedance (SZ) recordings.

( ) Pulse pressure decrease during exercise.

Answer 1

Question no 1 is true as unipolar Leads 2 leads situated on the right as well as the left wrist , AVr as well as the AVL respectively, and the lead situated on the left ankle of the leg of the individual AVf all these will make up a , triangle which is known as the "Einthoven's Triangle" and for the unipolar lead information is obtained from this triangle as well as from the v1 - v 6

Also the bipolar leads are the limb lead 1,2 and 3 so it is also correct .

The answer is correct as all of them are included in it
