Description
Summary:The early diagnosis of asymptomatic atrial fibrillation is important because of the associated risk for arterial embolism. Routine ECG recording, however, is not effective in asymptomatic patients. The goal of this article is to show the general practitioner and internist how the search for atrial fibrillation can be made more efficacious. For example, recording an ECG in patients older than 65 years with irregularities in their pulse or repeated ECG recording in patients older than 75 years with hypertension shows improved results in this regard. It is interesting that elements of the CHA2DS2-VASc score, which was developed to predict risk for arterial embolism, are also effective for defining populations to screen for atrial fibrillation. In the subgroup of patients with a pacemaker or implantable converter-defibrillator (ICD), histograms or intracardiac electrograms can be used to identify previously undiagnosed atrial fibrillation. The general practitioner should take these results which are usually obtained by a cardiologist into consideration in the follow-up treatment of his or her patients.
