1. The P wave is a sign of:  (Refer to the section on cardiac contribution to ECG in the physiology of cardiac conduction if you don't remember.)  

Explanation

The correct answer is atrial depolarization. The P wave in an ECG represents the depolarization of the atria, which is the electrical activation of the atrial muscle cells. This is the initial electrical signal that causes the atria to contract and pump blood into the ventricles.

This Is A Quiz On The ECG Unit - Quiz

This is a Quiz on the ECG unit. You must pass it with an 80% or better to pass the module.

2. The rate of ventricular contraction is noted by: (Refer to the section on determining heart rate from the ECG if you do not remember.)   

Explanation

The correct answer is the r to r wave interval. This interval represents the time between two consecutive R waves on an ECG, which corresponds to the contraction of the ventricles. By measuring the duration of the r to r wave interval, we can determine the rate of ventricular contraction, also known as the heart rate.

3. The normal configuration of the QRS complex in lead II is: (Refer to the section on ECG output.)  

Explanation

The normal configuration of the QRS complex in lead II is positive. This means that the QRS complex has a predominantly upward deflection in lead II of an electrocardiogram (ECG). A positive QRS complex indicates that the electrical depolarization of the ventricles is primarily moving towards the positive electrode in lead II. This is a normal finding and suggests that the electrical conduction system of the heart is functioning properly.

Submit
4. The placement for the chest lead, V6, is located:  (Refer to the section on chest /precordial leads to find the placement.)  

Explanation

The correct answer is on the left side of the chest in the left mid-axillary line in the 5th intercostal space. This is the correct placement for the chest lead V6, as indicated by the question.

Submit
5. Left axis deviation may indicate: (Refer to the section on ECG axis.)

Explanation

Left axis deviation on an ECG may indicate hyperkalemia. Hyperkalemia refers to high levels of potassium in the blood, which can affect the electrical conduction in the heart. This can lead to changes in the ECG, including a shift in the heart's electrical axis to the left. Therefore, the presence of left axis deviation on an ECG can be a clue to the possibility of hyperkalemia.
