Background: Supraventricular tachycardia (SVT) and ventricular arrhythmia’s are common causes of palpitations and syncope, with variable clinical presentations and outcomes. Radiofrequency (RF) ablation and cardioversion remain mainstays of definitive therapy in selected cases.
Case Series: We report three cases highlighting the clinical spectrum of arrhythmias. Case 1 involved a 44-year-old female with AVNRT and comorbid hypertension and hypothyroidism, successfully treated with RF ablation using 3-D electro anatomical mapping (EAM). Case 2 described a 38-year-old male with drug-refractory AVNRT and mild mitral valve prolapse, also successfully managed with RF ablation. Case 3 involved a 15-year-old boy with arrhythmogenic right ventricular dysplasia (ARVD) presenting with ventricular tachycardia; arrhythmia was refractory to antiarrhythmic therapy but reverted to normal rhythm after synchronized DC cardioversion.
Conclusion: This series illustrates the diverse presentation of supraventricular and ventricular arrhythmias, the role of advanced electrophysiologic interventions, and the importance of individualized management strategies to achieve optimal outcomes.
