1. Dog’s balls

· Normal vs abnormal

· Obvious pathology

2. Rate

Number of big squares:

1. 300

2. 150

3. 100

4. 75

5. 60

6. 48

Multiplication:

· Rhythm strip = 10 seconds

· HR = n(QRS) x 6

3. Rhythm

Where:

· Rhythm strip ± Lead V1

· Horizontal analysis – beat by beat

· Vertical analysis – line up with other leads

P:

· Regular vs irregular?

· Number of morphologies?

· Each followed by a QRS?
(DO NOT SAY: is each QRS preceded by P wave – N Strathmore)

QRS:

· Regular vs irregular?

· Broad vs narrow?

· Number of morphologies?

4. Axis

I	aVF	Axis
↑	↑	Normal
↑	↓	If ↑2: Normal If ↓2: Left
↓	↑	Right
↓	↓	Extreme

5. Waveforms

What:

· P (wide? tall?)

· PR (long? short?)

· Q (abnormal?)

· QRS (width? amplitude? R-wave progression?)

· ST (up? down?)

· T (inverted?)

· QT (long?)

Where:

· Inferior: 2, 3, aVF

· Anterior: V1-4

· Lateral: 1, aVL, V6
