# CTE Resource Center - Verso - Patient Care Technician Task 885059663

CTE Resource Center - Verso

Virginia’s CTE Resource Center

Demonstrate Holter monitor procedures.

Definition

Demonstration should include the following:
  • Calculate patient heart rate from the ECG tracing (e.g., 6-second method, R to R, sequencing).
  • Identify artifacts from the tracing (e.g., wandering baseline, somatic, electrical).
  • Resolve artifacts from the tracing (e.g., wandering baseline, somatic, electrical).
  • Record leads on a patient (e.g., 3-lead, 5-lead, 12-lead).
  • Verify the leads recorded on an ECG.
  • Upload a completed ECG to a patient’s electronic medical record.
  • Mount a completed ECG for a patient’s chart.
  • Measure a patient’s heart rhythm from the ECG tracing.
  • Inspect the waveforms of a cardiac cycle for symmetry, direction, and amplitude (e.g., P waves, QRS complexes, ST segments, T waves).
  • Measure a patient’s heart conduction from the ECG tracing (e.g., PR-interval [PRI], QRS duration, QT-interval).
  • Identify the major classifications of arrhythmias from the ECG tracing (e.g., sinus, atrial, ventricular, junctional).
  • Identify the major variances to waveforms related to ischemia, injury, or infarction.
  • Respond to potentially life-threatening arrhythmias.
  • Verify ECG machine paper speed (e.g., 25mm, 50mm).
  • Verify ECG machine sensitivity (e.g., h, 1, 2).
  • Maintain ECG equipment in the work environment.
  • Recognize pacemaker spikes on an ECG tracing.
