title: Intra-atrial Re-entrant Tachycardia with Wenckebach Periodicity creator: Sarubbi, Berardo creator: Vergara, Pasquale creator: D’Alto, Michele creator: Sessa, Francesco creator: Calabrò, Raffaele subject: Indian Pacing and Electrophysiology Journal description: A 15-year-old girl, previously asymptomatic for palpitations, underwent a successful atrial septal defect (ASD) device closure. Twelve weeks after the procedure, the patient was admitted complaining of dyspnoea on effort and palpitations. The twelve-lead ECG showed a narrow QRS tachycardia with slight heart rate irregularity, with a mean HR of 170bpm. P waves were not clearly identified with a suspicious of negative P-waves in II, III and aVF leads. No clear relationship could be observed between the suspected P waves and QRS complexes publisher: Indian Pacing and Electrophysiology Group contributor: Singh, Balbir contributor: Lokhandwala, Yash contributor: Francis, Johnson contributor: Gupta, Anup date: 2003-10 type: Journal (Paginated) type: PeerReviewed format: text/html identifier: http://cogprints.org/4254/1/sarubbi2.htm identifier: Sarubbi, Berardo and Vergara, Pasquale and D’Alto, Michele and Sessa, Francesco and Calabrò, Raffaele (2003) Intra-atrial Re-entrant Tachycardia with Wenckebach Periodicity.
