what is the einthovens triangle used for

Full Answer

Why use Einthoven's triangle?

Using Einthoven's triangle to identify lead misplacements. Though Einthoven's triangle is no longer used in contemporary ECGs, Einthoven's triangle can be helpful in the identification in incorrect placement of leads. Incorrect placement of leads can lead to error in the recording, which can ultimately lead to misdiagnosis.

How did Einthoven use the ECG?

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.

What dictates the direction of the trace on the ECG?

Polarisation dictates the direction of the trace on the ECG.

Which leads give additional views on a trace by reading potential difference across the heart in three more directions on the frontal?

These leads, aVR, aVL and aVF give additional views on a trace by reading potential difference across the heart in three more directions on the frontal plane.

What are the three limb electrodes?

The three limb electrodes, I, II and III form a triangle ( Einthoven’s Equilateral Triangle ), at the right arm (RA), left arm (LA) and left leg (LL). The three Standard Limb Leads: Einthoven’s Law explains that Lead II’s complex is equal to the sum of the corresponding complexes in Leads I and III and is given as II = I + III. For example, ...

How far apart are the axis of a triaxial reference system?

Each axis is separated by 60° from each other, with the lead polarity , + or -, remaining in the same direction. This is known as the Triaxial Reference System.

What is Einthoven's triangle?

Einthoven’s Triangle is an equilateral triangle drawn arbitrarily around an area of the heart, apices of which is represented by the right arm, left arm and left leg.

When ST segment and TP segment of ECG arc not at the same potential level, it is called?

when ST segment and TP segment of ECG arc not at the same potential level, it is called ST segment shift.

What is Einthoven's triangle?

Einthoven's triangle is an imaginary formation of three limb leads in a triangle used in electrocardiography, formed by the two shoulders and the pubis. The shape forms an inverted equilateral triangle with the heart at the center. It is named after Willem Einthoven, who theorized its existence.

How did Einthoven use the ECG?

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.
