Impact of Percutaneous Intervention Compared to Pharmaceutical Therapy on Complex Arrhythmias in Patients With Chronic Total Coronary Occlusion. Rationale and Design of the CTO-ARRHYTHMIA Study.

Chronic total coronary occlusions (CTO) occur in up to 50 % of patients with coronary artery disease by angiography. In CTO-patients, clinically significant arrhythmia is potentially important and insufficiently investigated. Therefore, the purpose of the CTO-ARRHYTHMIA study was to investigate the incidence of loop recorder detected clinically significant arrhythmias and the effect on arrhythmias of revascularization by CTO-PCI.
