Study Notes

EKG Procedures and Actions

Verify that EKG tracings are artifact-free before disconnecting the patient from the machine.
Communication within healthcare teams can occur through electronic health records and verbal exchanges.
Check a patient's respiratory rate during a stress test if hyperventilation is observed.

EKG Findings and Interpretations

A 2 mm ST elevation in leads I, AVL, V5, and V6 indicates a lateral infarction.
Detection of a U wave in a patient with chest pain necessitates immediate notification of the healthcare provider.

Patient Education and Compliance

Acknowledgment of smoking before an exam reflects the patient's understanding of the preparation for a stress test.
Proper modification of lead placements is necessary for patients with amputations, e.g., placing lower extremity lead on the left groin.

EKG Lead Placements and Techniques

Place V4R lead for right ventricular ischemia, especially in cases of suspected inferior wall myocardial infarction.
During a posterior 12-lead EKG, lead V9 should be positioned along the paraspinous border.
For holter monitor application, using stress loops on electrodes minimizes lead tension and reduces artifacts.

Patient Monitoring and Emergency Protocols

Monitoring for dizziness during exercise stress tests can indicate the need to stop the test.
Documenting the procedure post-holter monitor placement in the patient's health record is essential for accurate medical tracking.

Electrical Activity and EKG Readings

Electrical activity of the septal wall is captured by leads V1 and V2.
Adjust the EKG paper speed to 50 mm to spread out closely packed waveforms when indicated by rapid heart rates.

Contraindications and Precautions

Congestive heart failure is a critical condition that prevents a patient from participating in an exercise stress test.
Patients are advised to continue regular exercise while wearing a holter monitor for accurate monitoring.
