WORLDWIDE ASSESSMENT OF NURSES’ KNOWLEDGE IN CARDIAC ARRHYTHMIA INTERPRETATION AND MANAGEMENT

Abstract

This study evaluates the knowledge of global registered nurses regarding the interpretation and management of cardiac arrhythmia. The research aims to identify strengths and gaps in nurses’ electrocardiogram interpretation skills, emergency response decisions, and pharmacological competencies. We developed a structured 14-item questionnaire based on recent scientific literature and administered it to 30 registered nurses from diverse clinical settings. We analyzed the results using descriptive mathematical and graphical methods. Nurses demonstrate solid understanding of myocardial infarction recognition, asystole management, and anticoagulation in atrial fibrillation, but show major knowledge gaps in defibrillation energy levels, ventricular fibrillation recognition, and drug selection for bradycardia. These findings indicate inconsistent competency in managing life-threatening arrhythmia. The study concludes that nurses require regular electrocardiography training, simulation-based practice, and globally standardized educational programs to strengthen arrhythmia management skills. Improving these competencies supports safer clinical decision-making and enhances patient outcomes.
