Frequency of Atypical AVNRT in Patients Presenting with Narrow Complex Tachycardia
Abstract
ABSTRACT
Objective: To determine the frequency of atypical AVNRT in patients presenting with Narrow Complex Tachycardia.
Study Design: Descriptive Cross Sectional
Place and Duration of Study: Department of Cardiology, MTI-Hayatabad Medical Complex, Peshawar, from March, 2021 to March, 2022.
Methodology: Ninety-three patients of either aged 30 to 80 years diagnosed with narrow complex tachycardia by consultant cardiac electrophysiologist on ECG showing QRS duration of less than 120 milliseconds were included in this study. Patients were managed as per standard protocol which included comprehensive clinical evaluation such as patient history, physical examination and invasive electrophysiological study for the diagnosis and characterization of atypical Atrioventricular Nodal Reentrant Tachycardia (AVNRT).
Results: A total of ninety-three patients were studied with mean age of 43.08 years (SD = 9.07). Among the participants, 58.1% were male, while 41.9% were female. Majority of patients had Slow-Fast AVNRT (7.5%) followed by Fast-Slow AVNRT (3.2%), and Slow-Slow AVNRT in 2.2% patients.
Conclusion: This study underscored the importance of gender-specific variations in the prevalence of different AVNRT types and highlighted the impact of gender as a potential influencing factor in the manifestation of specific types of AVNRT within the study population.
