The 12-lead electrocardiogram (ECG) is an invaluable tool for the diagnosis of supraventricular tachycardia (SVT). Most forms of SVT can be distinguished with a high degree of certainty based on specific ECG characteristics by using a systematic, stepwise approach. This article provides a general framework with which to approach an ECG during SVT by describing the salient characteristics, ECG findings, and underlying electroanatomical relationships of each specific type of SVT encountered in adults. It concludes by providing a systematic algorithm for diagnosing SVT based on the findings of the 12-lead ECG.

    ABSTRACT: El diagnóstico diferencial de las taquicardias de complejo QRS estrecho (TQRSE) es un dilema común en los pacientes adultos que acuden a los servicios de urgencias. Algunas TQRSE (ej.: taquicardia sinusal) son secundarias a los motivos que propiciaron su consulta (ej.: fiebre, ansiedad, dolor) y responderán al tratamiento apropiado de la patología subyacente. Por otro lado, otras TQRSE (ej.: fibrilación auricular, taquicardia de reentrada nodal AV) pueden ser verdaderamente el origen de la sintomatología principal (ej.: palpitaciones, mareo secundario a la hipoperfusión) y deben ser positivamente identificadas y tratadas. Para un correcto diagnóstico es necesario conocer las semejanzas y diferencias entre las distintas TQRSE. Este artículo comenta cuáles son las características demográficas, clínicas y electrocardiográficas que son de ayuda para identificar los siguientes ritmos: taquicardia sinusal, taquicardia de reentrada del nodo sinusal, taquicardia auricular unifocal, taquicardia auricular multifocal, fibrilación auricular, "flutter" auricular, taquicardia de reentrada del nodo auriculoventricular y taquicardia de reentrada auriculoventricular. Además, se realiza un comentario sobre las distintas maniobras diagnósticas, que vincluye la administración de adenosina.

    ABSTRACT: The most common types of supraventricular tachycardia are caused by a reentry phenomenon producing accelerated heart rates. Symptoms may include palpitations (pulsation in the neck), chest pain, lightheadedness or dizziness, and dyspnea. It is unusual for supraventricular tachycardia to be caused by structurally abnormal hearts. Diagnosis is often delayed because of the misdiagnosis of anxiety or panic disorder. Patient history is important in uncovering the diagnosis, whereas the physical examination may or may not be helpful, and usually necessitates use of a Holter monitor or an event recorder to capture the arrhythmia and confirm a diagnosis. Treatment consists of short-term or as needed pharmacotherapy using calcium channel or beta blockers when vagal maneuvers fail to halt or slow the rhythm. In those who require long-term pharmacotherapy, atrioventricular nodal blocking agents or class IC or III antiarrhythmics can be used; however, these agents should generally be managed by a cardiologist. Catheter ablation is an option in patients with persistent or recurrent supraventricular tachycardia who are unable to tolerate long-term pharmacologic management. If Wolff-Parkinson-White syndrome is present, expedient referral to a cardiologist is warranted because ablation is a potentially curative option.
