What is the einthoven’s triangle used for?
The shape forms an inverted equilateral triangle with the heart at the center. It is named after Willem Einthoven, who theorized its existence. Einthoven used these measuring points, by immersing the hands and foot in pails of salt water, as the contacts for his string galvanometer, the first practical ECG machine.Click to see full answer….

Hereof, what leads to einthoven’s triangle?Lead III has the positive electrode on the left leg and the negative electrode on the left arm. These three bipolar limb leads roughly form an equilateral triangle (with the heart at the center) that is called Einthoven’s triangle in honor of Willem Einthoven who developed the electrocardiogram in the early 1900s.Similarly, what are the 3 bipolar leads? A 12-lead ECG consists of three bipolar limb leads (I, II, and III), the unipolar limb leads (AVR, AVL, and AVF), and six unipolar chest leads, also called precordial or V leads, ( , , , , , and ). Chest leads: , , , , , and . Similarly one may ask, what does lead2 measure? The activity of the heart produces electrical potentials that can be measured on the surface of the skin. Lead II records electrical differences between the left leg and right arm electrodes. In picture C, the negative electrode is on the left arm and the positive electrode is on the left leg (left lower chest).In which lead is the left arm negative (-) and the left leg positive?Lead II (pictured below, on left) connects the left leg as positive to the right arm’s negative. Lead III connects the left leg as positive to the negative left arm (pictured below, right).
