1

Which leads offer an inferior view of the heart?

II, III, aVF

2

Which leads offer a lateral view of the heart?

I, aVL, V5, V6

3

Which leads offer an anterior view of the heart?

V3, V4

4

Which leads offer a septal view of the heart?

V1, V2

5

Healthy individuals' axis on ECG?

Between -30 and +90

6

Which leads is the overall direction of electrical activity directed towards?

Leads I, II, III

7

Which lead are you expecting to see the most negative deflection?

aVR
- looks at the heart from the opposite direction

8

Right axis deviation common cause + signs?

Right ventricular hypertrophy (secondary to pulmonary hypertension)

Lead I deflection becomes negative
Leads III/aVF deflection becomes more positive

9

Left axis deviation signs?

Lead III + II become negative (has to be both)
- usually caused by conduction abnormalities

10

Sawtooth baseline represents?

Flutter waves

11

Chaotic baseline represents?

Fibrillation waves

12

How long is prolonged PR interval?

>0.2 seconds
