Presentation Transcript

  1. Slide Number Obtaining an ECG • Recording the ECG (see Procedure 48-1) • Standardization, sensitivity, and speed • Mounting an ECG tracing

  2. Slide Number Artifacts • The medical assistant must recognize and correct the most common types of artifacts on the ECG recording. • Wandering baseline

  3. Slide Number Artifacts • Somatic tremor

  4. Slide Number Artifacts • Sixty-cycle interference

  5. Slide Number Artifacts • Interrupted baseline

  6. Slide Number Sensitivity Standards Most machines have 3 sensitivity standards that can be selected

  7. Slide Number Sensitivity Standards (cont’d)

  8. Slide Number Typical ECG Rhythm Abnormalities • Sinus arrhythmias • Sinus bradycardia • Sinus tachycardia

  9. Slide Number Typical ECG Rhythm Abnormalities • Atrial arrhythmias • Premature atrialcontraction (PAC) • Atrial flutter • Ventricular arrhythmias • Premature ventricular contraction • Ventricular fibrillation

  10. Slide Number Typical ECG Rhythm Abnormalities

  11. Slide Number Biochemical Arrhythmias • Digitalis • Potassium

  12. Slide Number Stress Test • Conducted to observe and record the patient’s cardiovascular response to measured exercise challenges.

  13. Slide Number Holter Monitor • A portable system for recording the cardiac activity of a patient over a 24-hour period or longer. • The patient must keep a journal of all stressful events and activities during the entire time the monitor is worn. • A medical assistant is often responsible for instructing the patient in applying and removing the monitor.

  14. Slide Number Patient Education • Heart disease and stroke account for more than one third of all deaths. • Talk to the patient about factors that could be modified, and give him or her encouragement for any attempt at complying with these suggestions. • Include visual aids, posters, brochures.
