Spectral analysis of heart rate variability can be successfully used to evaluate the effectiveness of therapy. The use of this method gives an idea of the role of the autonomic nervous system in the regulation of chronotropic function of the heart. These data help to define conditions of manifestation of efficiency of antiarrhythmic drugs. In this study, spectral analysis were studied in patients with persistent atrial fibrillation. The effect of amiodarone class III antiarrhythmic drug were studied this study.

The use of the spectral analysis of the heart rate variability to assess the effectiveness of therapy is of great attention of researchers and doctors. This method allows you to get knowledge of the influence of the autonomic nervous system on the heart activity, which is an important factor for the manifestation of the effects of antiarrhythmic drugs. In this study, we studied the effect of antiarrhythmic drugs of class III amiodarone and sotalol on spectral indices of the heart rate variability in patients with atrial fibrillation. The power of slow frequencies prevailed in the structure of the spectrum with the introduction of amiodarone and sotalol. This suggests that the sympathetic nervous system have a predominant influence on the heart.

Spectral analysis of heart rate variability gives an idea of the role of the autonomic nervous system in the regulation of chronotropic heart function. This method can be used to evaluate the effectiveness of drug therapy. Drug therapy should be carried out taking into account the individual clinical form of atrial fibrillation. Information about the vegetative status of the patient will undoubtedly increase the effectiveness of treatment. In this study, spectral parameters were studied in patients with newly diagnosed atrial fibrillation. The effect of antiarrhythmic drug class III amiodarone on the spectral parameters of heart rate variability was studied.

Background: The efficacy of cryoballoon pulmonary vein isolation (Cryo-PVI) is equivalent to that of radiofrequency pulmonary vein isolation in patients with paroxysmal atrial fibrillation (AF). We aimed to compare the efficacy and safety profile of Cryo-PVI and high-power, short-duration (HPSD) radiofrequency catheter ablation (RFCA) in patients with AF. Methods: We prospectively randomized 314 patients with paroxysmal AF (men, 71.3%; 59.9±10.9 years old) to either the Cryo-PVI group (n=156) or HPSD-RFCA group (n=158). Cavotricuspid isthmus ablation and linear ablation from the superior vena cava to the right atrial septum in addition to pulmonary vein isolation were carried out in the majority of patients in the HPSD-RFCA group. The primary end point was AF recurrence after a single procedure; secondary end points were the recurrence pattern, cardioversion rate, follow-up heart rate variability, and response to antiarrhythmic drugs. Results: After a mean follow-up of 9.8±5.1 months, the clinical recurrence rate did not significantly differ between the two groups (log-rank P =0.840). The rate of recurrence as atrial tachycardia ( P >0.999), cardioversion ( P =0.999), and 3-month heart rate variability (high frequency; P =0.506) did not significantly differ. During the final follow-up, sinus rhythm was maintained without antiarrhythmic drugs in 70.5% of the Cryo-PVI group and 73.4% of the HPSD-RFCA group ( P =0.567). No significant difference was found in the major complication rate between the two groups (3.8% versus 0.6%; P =0.066), but total procedure time was significantly shorter in the Cryo-PVI group (78.5±20.2 versus 124.5±37.1 minutes; P <0.001). Conclusions: In patients with paroxysmal AF, the Cryo-PVI is an effective rhythm-control strategy with a shorter procedure time compared with the HPSD-RFCA.
