Unknown SVT Tracings: The Battle Of The Titans-Unknown SVT Tracings: The Battle Of The Titans

Video Transcription

Video Summary

The transcript from the Heart Rhythm 2025 conference reveals varied presentations addressing complex cases of supraventricular tachycardia (SVT). Dr. Feld and Dr. Hazegar initiated the session, emphasizing the importance of engaging through the HRS 2025 app for Q&A, where participants could interact live. Dr. Hiroshi Nakagawa, Dr. Gregory Michaud, and others discussed intricate cases involving unidentified SVT tracings, presenting electrocardiograms (EKG) for detailed examination. Participants analyzed different cardiac scenarios, focusing on the distinctive mechanisms and underlying conditions leading to varied cardiac rhythms.<br /><br />One discussed case involved a 71-year-old woman with recurring palpitations, linking her symptoms with a history of mesenteric artery thrombosis and warfarin therapy. The experts used the EKGs to explore differential diagnoses such as atrioventricular reentry tachycardia (AVRT), junction tachycardia, and other complex arrhythmic conditions. Entrainment and overdrive pacing techniques were employed to discern pathways and pinpoint the potential sources of arrhythmogenic activity within the heart's nodal and conduction systems.<br /><br />The panel of electrophysiologists, including Drs. Capato, Makar, Saliba, and Reginald, provided insights into challenging arrhythmia cases involving unique anatomical deviations, such as dual AV nodes and fascicular pathways—hinting at various clinical implications and therapeutic approaches, including precise ablation strategies. The session underscored the crucial interaction of clinical electrophysiology, diagnostic imaging, and procedural interventions in managing sophisticated heart rhythm disorders, offering contemporary perspectives and procedural nuances to enhance treatment efficacy.
