"ECG - Heart Axis Calculator" is designed to determine heart axis in vector degrees from an electrocardiogram (ECG) result. The heart axis represents the major vector of ventricular activation, which is the overall direction of electrical activity. It is important to assess the heart axis of a patient with suspected heart disease.

Why should you choose "ECG - Heart Axis Calculator"?
- Simple and very easy to use ECG app.
- Accurate and precise calculation of cardiac or heart axis.
- The electrical heart axis is shown in vector degrees.
- Interpretation of the vector degrees result, namely normal heart axis, left axis deviation (LAD), right axis deviation (RAD), and extreme axis deviation.
- It is totally free. Download now!

"ECG - Heart Axis Calculator" is a simple application to determine heart axis by using an electrocardiogram (ECG) reading. "ECG - Heart Axis Calculator" app is designed to help health professional in clinical practice, intensive care, or emergency department. Heart axis or cardiac axis is the direction of action potentials during ventricular depolarization. In "ECG - Heart Axis Calculator" app, you need to input the QRS complex deflection in lead I and lead AvF. The electrical heart axis will then be shown in vector degrees. The interpretation of the vector degrees result is provided. There are 4 interpretations in "ECG - Heart Axis Calculator" app, namely normal heart axis, left axis deviation (LAD), right axis deviation (RAD), and extreme axis deviation.

Disclaimer: all calculations must be re-checked and should not be used alone to guide patient care, nor should they substitute for clinical judgment. Calculations in this “ECG - Heart Axis Calculator” app might be different with your local practice. Consult to expert doctor whenever necessary.
