Question

Looking at the ECG given, answer the following questions.

1. Does this ECG display an irregular, inconsistent rate?

2. Is this ECG missing one or more waveforms? If so, which ones?

3. Given that the normal ranges for the following durations are: PR interval (0.12-0.2 sec), QRS complec (0.08 - 0.1 sec), QT interval (0.32-0.42 sec), list any abnormal:

4. Does this ECG have a conduction system problem?

5. Does this ECG have a problem originating in the atrial muscle?

6. Does this ECG have a problem originating in the ventricular muscle?

Explanation / Answer

1. This ECG display a regular rate.

2.No missing waveform in this ECG.

3. Increased PR interval in the later waveform.

4.This ECG have a conduction problem ie; 1st degree AV block.In the majority of cases, it is due to delayed conduction in the AV node.

5. No

6. No
