The electrical axis of the heart (heart axis): ECG ... The electrical axis of the heart (heart axis). As evident from the figure, the normal heart axis is between -30° and 90°. If the axis is more positive than 90° it is referred to as right axis deviation. If the axis is more negative than -30° it is referred to as left axis deviation. The axis is calculated (to the nearest degree) by the ECG machine. 12-Lead ECG Placement Guide with Illustrations 3-Lead ECG A 3-Lead ECG uses 3 electrodes that are labeled white, black, and red. These colors are not universal as two coloring standards exist for the ECG (discussed below). These 3 leads monitor rhythm monitoring but doesn't reveal sufficient information on ST elevation activity. 5-Lead ECG. A 5-Lead ECG uses 4 limb leads and 1 chest lead.

The normal QRS axis is between -30 and +90 degrees. The most efficient way to estimate axis is to look at leads I + aVF. The diagram below illustrates the relationship between QRS axis and the frontal leads of the ECG. Heart Axis Calculation - My EKG Before calculating the heart axis, we must understand that each lead represents a different point of view of the same electrical stimulus.. To calculate the cardiac axis we will only use the limbs leads. Taking the example of the bus, the Limbs Leads are 6 windows that look to the heart in the frontal plane, that is: from above, below, left and right.. Never from the front or back si
