Background To investigate the effect of left ventricular function in elderly hypertensive patients with paroxysmal atrial fibrillation passing radiofrequency catheter ablation.Methods Selected patients elder than 65 years old, with hypertension and paroxysmal atrial fibrillation.The circumferential pulmonary vein antrum linear catheter ablation were performed to eleetrically isolated pulmonary vein.The blood pressure of all of the patients were strictly controlled down to the standard (＜140/90 mmHg).All the patients were followed up for 12 months after operation.The changes of left atrium diameter, LV end-systolic and end-diastolic diameter, left ventricular ejection fraction, left ventricular septal and posterior wall thickness, blood NT-proBNP level were compared pre and postoperative at the end of the follop-up.
