Abstract/OtherAbstract:
AIMS: This prospective pilot-study was performed to assess whether regular moderate physical activity elevates the parasympathetic tone to the atrio-ventricular node and decreases VR during permanent AF. BACKGROUND: Adequate ventricular rate (VR) control in patients with permanent atrial fibrillation (AF) is not easy to accomplish. METHODS: 10 patients (mean age 59 +/- 10 years) with permanent AF (duration: 10 +/- 8 years) underwent moderate physical exercise adjusted to their individual physical capability (45 min walking/jogging twice a week). To analyze VR control physical exercise tests and Holter-ECG recordings were performed before and after 4 months. In addition, stepwise lactate tests and psycho-pathometric examinations were obtained. RESULTS: After 4 months of training, there was a trend toward a decrease of mean VR in 24 h Holter-ECGs by 12% from 76 +/- 20 to 67 +/- 12 bpm (P = 0.05) while there was no significant decrease of the minimal VR (38 +/- 8 vs. 36.3 +/- 4.5 bpm, P = 0.54). At a lactate threshold of 2 mmol/l there was a trend towards an increase of the running speed from 105 +/- 11 to 116 +/- 12 m/min (P = 0.05). A significant VR decrease of 8% (range 5-10%) was observed at almost all exercise levels during exercise treadmill testing. Increases of exercise capacity and decreases of VR were accompanied by subjective improvements of health perception. CONCLUSION: Regular moderate physical activity decreases VR at rest and during exercise while increasing exercise capacity. Physical training should be taken into account for ventricular rate control during AF.
