This BSL lesson provides an introduction to the electrocardiograph and the recording of the heart’s electrical signal. The lesson familiarizes the students with a Lead II ECG recording and with the components of the ECG complex. They will learn to correlate the electrical events of the ECG (P, Q, R, S & T components) with the mechanical events of the cardiac cycle. Students will perform a number of tasks designed to promote changes in the ECG complex, and then perform a detailed analysis of their ECG recording.
To become familiar with the electrocardiograph as a primary tool for evaluating electrical events within the heart.
To correlate electrical events as displayed on the ECG with the mechanical events that occur during the cardiac cycle.
To observe rate and rhythm changes in the ECG associated with body position and breathing.
Tasks Performed by the Student
BSL Lessons are designed to allow at least four students to record and save data in a normal lab period (60-90 minutes). Typically, labs work most efficiently with three or more students working together at each BSL station.
Record Lead II ECG.
Event mark each new activity.
Lie down and relax.
Take 5 deep breaths.
Perform a physical exercise to increase the heart rate.
Relax while heart rate returns to normal.
The display uses classic, clinical grid markings for quick and easy evaluations.
The user can turn the grid markings on or off.
The baseline can be adjusted for precise analysis and printing.
Zoom in for a closer look at an individual ECG complex.
The student can perform a detailed analysis of the ECG data.
See how the ECG complex changes under different conditions.
Place markers for each of the ECG components (P,Q,R,S &T).
Convenient electrode placement (wrists and ankles).
The software automates the calibration procedure for the student.
There are no knobs and dials to confuse students.
On-screen commands prompt the students throughout the lesson.
BIOPAC’s Simple Sensors warn students if they plug the wrong device into the system.
The lesson will also work as part of a group study.
BSL Instructor’s Guide provides lab tips and lesson options.
BSL Answer Guide included.

The STMEPM Programmable Stimulation System for E-Prime allows a user to interface the STMISOLA Stimulator with E-Prime to control the stimulus frequency and stimulus intensity for real-time stimulus delivery changes based on a subject’s responses. It is also possible to hardcode the stimulus intensity levels in the presentation so that predefined stimulus levels are delivered […]
The new issue of Psychophysiology has a study “Quantifying rapid changes in cardiovascular state with a moving ensemble average” using MEAP for preprocessing/analysis and BIOPAC hardware and software for data collection, display, and storage. The proof of concept study demonstrates a viable method for the adoption of ICG measures across the field of psychophysiology. MEAP (moving ensemble […]
BIOPAC provides software and hardware that allow for research teams to record and analyze respiration activity in physiological experimentation. Here are a few notable studies covering MRI, ECG, and Laser Doppler Flow measurement. fMRI & Thermal Perception: The neural mechanisms underlying thermal perception (how hot or cold we perceive the temperature to be) have not been fully […]
