ECG Sinus Rhythm Basics

A normal heart rhythm contains a P wave, a QRS, and a T wave. Knowing the normal amplitude, deflection, and duration of each component is essential to accurate rhythm and ECG interpretation.

Amplitude:

This measures the voltage of the beat and is determined by how high the wave reaches, as measured by each square vertically on the chart.

10 mm = 1mV; 5 squares = 0.5mV and 2.5 squares = 0.25 mV.

Deflection: 

Which lead on the patient it is coming from.

Duration:

How long it is, as measured by squares going horizontal.
