Insights

Radiofrequency ablation near cardiac implantable electronic devices can cause inappropriate shocks and pacing inhibition. Following best practices is crucial to prevent adverse events in patients with these devices.

Area of Science:

  • Pain Management
  • Cardiology
  • Interventional Pain Medicine

Background:

  • Cervical spondylosis and complete heart block are common conditions.
  • Cardiac implantable electronic devices (CIEDs) like cardiac resynchronization therapy defibrillators are increasingly implanted.
  • Radiofrequency ablation (RFA) is a common procedure for chronic pain.

Observation:

  • A patient with a CIED (cardiac resynchronization therapy defibrillator) underwent C4-C6 medial branch RFA.
  • The procedure triggered remote monitoring alerts, including inappropriate shocks and pacing inhibition.

Findings:

  • Fluoroscopy-guided RFA in proximity to a CIED can lead to device malfunction.
  • Inappropriate shocks and pacing inhibition are potential adverse events.

Implications:

  • Adherence to established best practice guidelines is essential for patient safety during RFA in patients with CIEDs.
  • Minimizing electromagnetic interference during RFA procedures is critical for preventing CIED complications.

Cardiopulmonary Resuscitation III: AED Use

Introduction to AEDAn Automated External Defibrillator (AED) is a portable medical device that analyzes the heart's rhythm and, if necessary, delivers an electrical shock to help the heart re-establish an effective rhythm during sudden cardiac arrest (SCA). SCA occurs when the heart suddenly and unexpectedly stops beating, leading to a loss of blood flow to the brain and other vital organs. In such emergencies, time is of the essence, and using an AED, combined with Cardiopulmonary...

Cardiopulmonary Resuscitation IV: Pharmacological Management

Pharmacologic intervention is crucial in treating cardiac arrest patients during ACLS or Advanced Cardiovascular Life Support. The ACLS algorithms guide the administration of specific drugs based on the patient's cardiac arrest rhythm, which includes pulseless ventricular tachycardia (VT), ventricular fibrillation (VF), asystole, and pulseless electrical activity (PEA).EpinephrineIndication: Epinephrine is the first-line drug for all cardiac arrest rhythms.Mechanism of Action: Epinephrine...

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...

Disturbances in Heart Rhythm01:29

Disturbances in Heart Rhythm

Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow heart...

Cardiac Catheterization IV: Nursing Management

Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...
