ECG 2 explains Einthoven’s triangle. Students record Leads I and III while performing a number of tasks designed to change the rhythm of the heart. They then analyze the data and estimate the mean QRS axis and potential.
To record ECG from Leads I and III in the following conditions: lying down, sitting up, and breathing deeply while sitting.
To compare the direction of the QRS complex (+ or -) with the direction of the lead axis.
To estimate the mean ventricular potential.
To estimate the mean electrical axis of the QRS complex.
Tasks Performed by the Student
Record ECG using bipolar Leads I and III.
Lie down and relax.
Sit and relax.
Breathe in and out once in each position.
The software makes it very easy for the student to compute the ECG vectors.
Classic, clinical grid markings available for quick and easy evaluations.
See how the ECG complex changes under different conditions.
Students place markers for each component (P, Q, R, S, and T).

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 HRV, EMG, and EEG measurement. HRV (Jing Wei, Hong Luo, Si J. Wu, Paul P. Zheng, Genyue Fu, and Kang Lee) Humans encounter various stressful situations everyday at work, home, and school. Such stress when experienced at high degrees and/or […]
Alan Macy Answers Proust Questionnaire BIOPAC co-founder and R&D Director, Alan Macy, was interviewed recently by Roger Durling for the Santa Barbara Independent. The article, “The S.B. Questionnaire: Alan Macy,” provided a background excerpt of the Santa Barbara entrepreneurs’ past as well as his answers to the Proust Questionnaire. The biomedical technology developed at BIOPAC reflects an ambitious […]
