CPCT Domain 5: EKG

A patient's EKG shows a regular rhythm with a rate of 55 bpm, a P wave preceding each QRS complex, and a PR interval of 0.20 seconds. Which of the following is the most likely diagnosis?

During an EKG, a technician notes that the T waves are inverted in leads II, III, and aVF. What does this indicate?

What EKG finding is indicative of hyperkalemia?

What is the significance of a PR interval that progressively lengthens until a QRS complex is dropped?

On an EKG, a regular rhythm with three premature beats having abnormal QRS complexes without preceding P waves is noted. These beats occur with a pattern, after every two normal beats. This pattern is most indicative of:

Which of the following EKG findings is most suggestive of left ventricular hypertrophy?

A technician observes a P wave with a different morphology followed by a QRS complex that arrives earlier than expected. This pattern repeats irregularly throughout the strip. The most likely explanation is:

In an EKG, a pattern of QRS complexes wider than 0.12 seconds, occurring without preceding P waves and with an irregular rhythm, suggests:

What does an EKG segment showing ST elevation in leads V1 through V4 suggest?

An EKG displaying a delta wave and shortened PR interval is most consistent with:

On an EKG, which finding is consistent with a diagnosis of pericarditis?

An EKG displays a regular rhythm with narrow QRS complexes at a rate of 160 bpm. No discernible P waves are present, and the rhythm is originating above the ventricles. This is most indicative of:

What is the significance of a biphasic P wave in lead V1 on an EKG?

On an EKG, a patient exhibits a rhythm that is irregularly irregular with no P waves before the QRS complexes. The most likely diagnosis is:

The presence of Q waves in leads V1 to V3 on an EKG is most suggestive of:

A patient's EKG shows a widened QRS complex (>0.12 seconds) and an RSR' pattern in leads V1 and V2. This finding is indicative of:

An EKG strip demonstrates a gradual decrease in the amplitude of the QRS complexes followed by a disappearance of the QRS complexes for a brief period. This pattern repeats cyclically. What does this suggest?

On an EKG, what does the presence of U waves, particularly after a prolonged QT interval, suggest?

An EKG showing ST depression and T wave inversion in leads I, aVL, V5, and V6 suggests myocardial ischemia in which region of the heart?

What does a normal sinus rhythm with an occasional QRS complex that appears prematurely without a preceding P wave, and with a QRS shape differing from the sinus beats, indicate?
