What is an EKG?

An electrocardiogram (EKG) records the electrical activity of the heart. It helps identify heart rhythms and detect abnormalities.

Basic EKG Components

P Wave: Atrial contraction
QRS Complex: Ventricular contraction
T Wave: Ventricular recovery

Simple Step-by-Step Approach

Check the heart rate (slow, normal, or fast)
Look for P waves
Assess rhythm regularity
Evaluate QRS width
Match pattern to known rhythms

Common Rhythms

Normal Sinus Rhythm
Atrial Fibrillation
Ventricular Tachycardia
Asystole
