What is einthoven’s triangle and what does the axis refer to?
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.Click to see full answer. Similarly, it is asked, what is einthoven’s law?Einthoven’s law.

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.Click to see full answer. Similarly, it is asked, what is einthoven’s law?Einthoven’s law. [īnt´ho-venz] if electrocardiograms are taken simultaneously with the three limb leads, at any given instant the potential in lead II is equal to the sum of the potentials in leads I and III.Beside above, how is the electrical axis of the heart determined? Step 1: Determine the heart rate. Step 2: Measure important intervals. Step 3b: Calculate the electrical axis. Step 3c: Calculate the electrical axis. Step 4: Evaluate the cardiac rhythm. Step 5: Inspect P waves for atrial enlargement. Step 6: Inspect QRS complexes for ventricular hypertrophy or low voltage. Herein, what does axis mean in ECG? The electrical axis of the heart (heart axis) Although often ignored, assessment of the electrical axis is an integral part of ECG interpretation. The electrical axis reflects the average direction of ventricular depolarization during ventricular contraction.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).
