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.
