[Electrical alternans, electrocardiogram pattern in the diagnosis of a severe heart disease]. / Alternancia eléctrica, patrón electrocardiográfico en el diagnóstico de enfermedad cardiaca grave.

Electrical alternans is a broad term that describes alternate-beat variation in the direction, amplitude and duration of any component of the ECG wave-form. It is associated with cardiac tamponade, serious ventricular arrhythmias, and sudden death. We present the clinical case of a 77-year-old female with electrical alternans, from which a diagnosis of cardiac tamponade was established.

La alternancia eléctrica es un amplio concepto que describe las variaciones, latido a latido, en la dirección, amplitud y/o duración de cualquier componente del electrocardiograma. Se asocia a taponamiento cardiaco, arritmias malignas y muerte súbita. Presentamos el caso de una paciente de 77 años con alternancia eléctrica a partir de la cual se llegó al diagnóstico de taponamiento cardiaco (AU)
