L06 Electrocardiography II

BSL ECG Einthoven's law

This BSL lesson explains Einthoven’s triangle and allows the students to record their ECG using bipolar Leads (I, II, and III). The students will attach Leads I and III and the software will calculate Lead II for them, using Einthoven’s law. The system displays the data for all three Leads. The students will perform a number of tasks designed to change the rhythm of the heart. They will analyze the data and calculate the Mean Electrical Axis of the heart.

Experimental Objectives

  1. Record ECG from Leads I and III in three conditions: lying down, sitting up, and breathing deeply while sitting.
  2. Review the ECG for Lead II.
  3. Correlate the direction of the QRS complex (±) with the direction of the Lead axis.
  4. Estimate the Mean Electrical Axis of the QRS complex using two methods.

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.

Dyadic Interactions Involving Parents, Children, Couples, and More | Recording from Multiple Participants Part I

Synchronizing Data from Multiple Participants
Performing a dyadic experiment takes more planning than single-participant studies. Data must be tightly synchronized, equipment must remain inobtrusive, and the experimental paradigm drives the optimal setup. Join us to learn how to record high-quality synchronized data for a wide range of applications.

What You Will Learn:
– How to synchronize data from two participants
– Recording options: ECG, EDA, EEG, fNIRS, Video
– Collaborative virtual environments
– Data analysis techniques
– Practical tips—and advice on working with children
– New ideas about your research

Live Webinar: May 20th at 8AM PT/11AM ET
