EKG Case Study

Learning Goal: I’m working on a health & medical case study and need the explanation and answer to help me learn.

Please answer all of the following questions. Each one is worth 1/3 of a point. From the EKG provided.

Below is the attachment of the lecture notes too.

• What is the heart rate?

• Is each QRS complex preceded by a normal P wave?

• Are the P waves upright in all leads except for aVR?

• Are the P waves less than 0.12 seconds in duration?

• Are any of the P waves greater than 2.5 mm in the inferior limbs or greater than 1.5 mm in V1 or V2?

• Is there a second hump to the P wave in lead 2?

• What is the axis orientation?

• Is the PR segment at baseline?

• Is the PR interval between 0.12 and 0.2 seconds in all leads?

• Is the QRS complex <0.12 seconds in all leads?

• Are there any Q waves in two or more neighboring leads that are greater than or equal to 0.04 seconds or greater than 25% of the corresponding R wave amplitude?

• Is there a Q wave in lead 3?

• If so, is there S1Q3T3?

• Is there R wave progression from V1 to V5 and then diminishment from V5 to V6?

• Add the depth of the S wave in V1 or V2 (whichever is deepest) to the height of the R wave in V5 or V6. Is the total <35 mm?

• Is the R wave in aVL greater than or equal to 10 mm?

• Is the R wave in lead 1 greater than or equal to 12 mm?

• Is the R wave in aVF greater than or equal to 20 mm?

• Is there an RSR’ pattern in V1 with R’ greater in amplitude than R?

• Are there broad monomorphic R waves without Q waves in leads 1 and V6?

• Is the R wave in either V1 or V2 greater than the corresponding S wave?

• Is there an S wave in lead 1?

• Is there a dominant S wave in V1?

• Is there slurring of S waves in either lead 1 or V6?

• Is there significant ST deviation in any of the leads? If so, which ones?

• Is each T wave concordant with the preceding QRS complex?

• Are there any tall and peaked T waves?

• Using Bazett’s formula, what is the patient’s QT interval?

• What is the pattern of this EKG?

• Please state three differential diagnoses specific to this EKG pattern.
