A

Which of the following does this ECG best represent?

First degree heart block

Second degree, Mobitz 2 heart block
Third degree heart block

none of the electrical impulses are conducted through the AV node, and that’s why it’s also called complete heart block.

So in 3rd degree AV block, the ventricles recognize that they’re not getting any impulses, and respond by generating their own electrical rhythm called a ventricular escape rhythm, just to hang on to dear life.

Because the atria and the ventricles each have their own pacemakers, they now contract independent of one another, which is called AV dissociation. This desynchronization of the heart chambers can reduce cardiac output dramatically, leading to syncope or even sudden cardiac death.

On the ECG, the P-waves and QRS complexes have nothing to do with each other, each appearing at their own rates.

A

Based on the quadrant diagram shown, which region would you expect the mean electrical axis to deviate towards in a patient with left ventricular hypertrophy?

A
B
C
D

Left ventricular hypertrophy results in a thickening of the cardiac muscle. The increase in mass increases the magnitude of the depolarisation wave on the left side of the heart. This causes the left axis deviation.
