Chapter 92 | Vector in Physiology Explained ???? | ECG Axis, Force & Direction (Sembulingam) Made Ea

In physiology, especially in cardiac electrophysiology, a vector represents a quantity that has both magnitude and direction, such as electrical activity in the heart.

This concept is widely used in understanding:

ECG (Electrocardiogram)
Cardiac electrical axis
Spread of depolarization & repolarization
???? What You’ll Learn
What is a vector in physiology?
Scalar vs vector (medical context)
Vector representation in the human body
Electrical vectors of the heart
Mean electrical axis (MEA)
Vector changes in ECG leads
Clinical significance of vector interpretation

In ECG
Each wave represents a vector of electrical activity
QRS complex → ventricular depolarization vector
Mean Electrical Axis shows overall direction of current flow
⚕️ Clinical Significance
Helps interpret ECG
Detects:
Left axis deviation
Right axis deviation
Ventricular hypertrophy
Conduction abnormalities
