ECG Normal Variant Poster

Why does the ECG evaluation process take so long?

Many common ECG findings are normal variants and are not cause for deferment, unless the pilot is symptomatic or there are other concerns.

How do you identify ECG normal variants?

Let’s look at a few examples.

Ectopic Atrial Rhythm

Sinus Bradycardia

Left Atrial Enlargement

Intraventricular Conduction Delay (IVCD)

(Complexes do not appear like a Rt or Lt BBB) Abnormally wide QRS complex

Left Axis Deviation

(less than or equal to -30 degrees)

Short QT Interval

(with no history of arrythmia)

Sinus Tachycardia

Sinus Arrhythmia

Wandering Atrial Pacemaker

Early Repolarization

(Defined as appearance of a J wave on a normal heart beat pattern)

Indeterminate Axis

Low Voltage Electromotive Force

(Make sure the ECG is performed with 10mm standardization)

Single Premature Ventricular Contraction (PVC)

Low Atrial Rhythm

First-degree AV Block With PR Interval Between 0.21 and 0.29 Seconds

Two Or More Premature Atrial Contractions In A Pilot Less Than 50 Years Old

Two Or More Premature Atrial Contractions In A Pilot Less Than 50 Years Old

Left Ventricular Hypertrophy By Voltage Criteria Alone

Incomplete Right Bundle Branch Block

(IRBBB)
