Electronics and Communication Engineering Biomedical Signal Processing Lab Experiments

Acquisition of ECG signals using biomedical systems

STEP 1: Patient, Electrode and ECG Machine Placement

  1. Drag the patient model from the component section and position it onto the bed.
  2. Drag each electrode and place it securely on the designated areas of the patient's body.
  3. Drag the ECG machine and place it onto the provided stand.

STEP 2:
Select Lead from the dropdown Select Lead to view the corresponding signal.

allLead: RA, LA, LL, RL, V1, V2, V3, V4, V5, V6

STEP 3: Establish Connections
1. Connect V-leads:

  1. Connect the V1 lead from the ECG machine to the V1 electrode on the patient's body.
  2. Connect the V2 lead from the ECG machine to the V2 electrode on the patient's body.
  3. Connect the V3 lead from the ECG machine to the V3 electrode on the patient's body.
  4. Connect the V4 lead from the ECG machine to the V4 electrode on the patient's body.
  5. Connect the V5 lead from the ECG machine to the V5 electrode on the patient's body.
  6. Connect the V6 lead from the ECG machine to the V6 electrode on the patient's body.

2. Connect Limb Leads:

  1. Connect the RA (Right Arm) lead from the ECG machine to the RA electrode on the patient's body.
  2. Connect the LA (Left Arm) lead from the ECG machine to the LA electrode on the patient's body.
  3. Connect the RL (Right Leg) lead from the ECG machine to the RL electrode on the patient's body.
  4. Connect the LL (Left Leg) lead from the ECG machine to the LL electrode on the patient's body.

Refer to the accompanying figure for correct connection points.


STEP 4:
Click the Check button to confirm the integrity of the established connections.

STEP 5:
If the connection check indicates an error, click the Reset button to clear all the connections and restart the process.

STEP 6:
Click the Show Signal button to display the simulated ECG waveform.

STEP 7:
Use the Toggle Sound button to enable or disable auditory feedback.

STEP 8:
Use the Pause Signal button to pause or resume the displayed ECG waveform.

STEP 9:
Click the Print button to save the recorded observations.
