Electrical cardioversion with 150 J successfully restored sinus rhythm in a 25-year-old woman presenting with recurrent syncope and a rapid, irregularly irregular pulse of 230 beats/min.
Case Report (n=1)
Immediate electrical cardioversion successfully restored sinus rhythm in a young woman presenting with syncope and a rapid, irregularly irregular tachycardia with hypotension.
Single-case success does not change practice; leaves open systematic study of rare tachycardias causing syncope in young adults.
A previously well and active 25 year old woman with no underlying structural heart disease presented with recurrent episodes of new onset syncope over a period of six hours. Her pulse was irregularly irregular at a rate of 230 beats/min. She was hypotensive with a blood pressure of 80/60 mm Hg. Twelve lead surface electrocardiogram (ECG) taken on admission is shown in fig 1. She was immediately electrically cardioverted to sinus rhythm with 150 J. She reported no history of recreational drug use or family history of sudden cardiac death. Fig 1 Surface electrocardiogram during …
