H01 12-Lead ECG

This BSL PRO lesson describes the hardware and software setup necessary to record a 12-lead ECG.

Experimental Objectives

1. To record each lead of the standard 12- lead ECG (Lead I, Lead II, Lead III, aVR, aVL, aVF, V1, V2, V3, V4, V5, V6).
2. To observe changes in the frontal plane vectors throughout a cardiac cycle.

Tasks Performed by the Student

You will record six 10-second segments, for a total recording of 60 seconds. You will record Lead I, Lead II and a Precordial (chest) lead in six positions (V1 through V6). In addition, Lead III and the “Augmented leads” (aVr, aVl, aVf) will be calculated. Each chest electrode is positive and the whole body is used as the common ground.
