Slide Number Obtaining an ECG • Recording the ECG (see Procedure 48-1) • Standardization, sensitivity, and speed • Mounting an ECG tracing
Slide Number Artifacts • The medical assistant must recognize and correct the most common types of artifacts on the ECG recording. • Wandering baseline
Slide Number Artifacts • Somatic tremor
Slide Number Artifacts • Sixty-cycle interference
Slide Number Artifacts • Interrupted baseline
Slide Number Sensitivity Standards Most machines have 3 sensitivity standards that can be selected
Slide Number Sensitivity Standards (cont’d)
Slide Number Typical ECG Rhythm Abnormalities • Sinus arrhythmias • Sinus bradycardia • Sinus tachycardia
Slide Number Typical ECG Rhythm Abnormalities • Atrial arrhythmias • Premature atrialcontraction (PAC) • Atrial flutter • Ventricular arrhythmias • Premature ventricular contraction • Ventricular fibrillation
Slide Number Typical ECG Rhythm Abnormalities
Slide Number Biochemical Arrhythmias • Digitalis • Potassium
Slide Number Stress Test • Conducted to observe and record the patient’s cardiovascular response to measured exercise challenges.
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.
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.
