چکیده
Background: Atrial Fibrillation (AF) is the most common chronic arrhythmia. Strategies to control the ventricular rate nowadays are well accepted. Many patients receiving medication to control the ventricular rate have no symptoms, but may have inappropriate ventricular responses despite normal routine examinations, including heart auscultation and ECG. Patients who seem to have the appropriate ventricular response but complain of symptoms should be investigated further. Material and Methods: Sixty-two patients with AF who were treated under the rate control and in their clinical examinations seemed to have the proper ventricular response were evaluated by 24-hour Holter monitoring. The patients were instructed to write down any symptoms, including pre-syncope, weakness, dizziness, palpitation, and syncope during the monitoring process. The results from Holter monitoring were printed, and the clinical manifestations that were associated with the events recorded by Holter monitoring were analyzed. Results: Only 11.3% of the patients with AF undergoing treatment and control of the ventricular rate appeared to have had an appropriate ventricular response. The incidence of syncope and presyncope had concurrency with considerable compensatory pauses of more than 5 seconds. The most common clinical symptoms were dizziness and palpitation, which had the most concurrency with a rapid ventricular response. The ventricular response from the patients with combined digoxin and beta-blocker medication regimens was more appropriate than that of the other patients. Conclusion: Evaluation of the ventricular response in patients with AF using only routine examinations, including auscultation and ECG, is not reliable and conducting a 24-hour Holter monitoring is reliable and more useful in this regard.
