ECG 1 introduces the electrocardiograph and the recording of the hearts electrical signal. Students learn about Lead II ECG recording and the components of the ECG complex. They also learn to correlate the electrical events of the ECG (P, Q, R, S, and T components) with the mechanical events of the cardiac cycle. After performing a number of tasks designed to promote changes in the ECG complex, students analyze their own ECG recording.
To become familiar with the electrocardiograph as a primary tool for evaluating electrical events within the heart.
To observe rate and rhythm changes in the ECG associated with body position and breathing.
Tasks Performed by the Student
Lie down and relax.
Take five deep breaths.
Perform a physical exercise to increase heart rate.
Relax while heart rate returns to normal.
Rate and ECG signals can be overlapped for easy interpretation of the data.
The baseline can be adjusted for precise analysis and printing.
Zoom in for a closer look at an individual ECG complex.
See how the ECG complex changes under different conditions.
Convenient electrode placement (wrists and ankles).

The Human Anatomy & Physiology Society (HAPS) found that BIOPAC’s Student Lab System (BSL) and AcqKnowledge software were the number one ranked data acquisition and analysis systems for physiology experiments performed in introductory A&P labs. According to HAPS surveys conducted in 2013 and 2016, BIOPAC products are used and preferred by members in more labs than […]
Hardware and software packages from BIOPAC allow commercial consumer marketing teams to easily combine precise eye tracking data with physiological data recording. Here are a few notable studies recording physiology with eye tracking data: Predicting Advertising Success: While neurophysiological methods have become increasingly popular to better understand marketing phenomena among academics and practitioners, the success of […]
