Abstract
CASE REPORT
This article reports the case of a 76-year-old patient with multiple implantable cardioverter defibrillator (ICD) interventions of the single chamber ICD. On admission the 12-lead electrocardiogram (ECG) documented a wide QRS complex tachycardia without clearly identifiable P waves. The patient had previously had two ventricular tachycardia (VT) ablations due to VT storms. The resting ECG revealed a sinus rhythm with a wide QRS complex. During the electrophysiological investigation typical atrial flutter could be detected and an ablation of the cavotricuspid isthmus was performed. During the follow-up period, the patient has been free from tachycardia.
CONCLUSION
The case described emphasizes that a differentiation between supraventricular tachycardia (SVT) and VT based on a stored ECG without an atrial channel can be challenging.
