However, this issue is still debated and in contrast to the above findings, there are

randomized controlled studies such as the CAPRAF-study that show neutral results.66 Brefeldin A mw anticoagulation has been proposed as treatment in patients with IAB to prevent embolic stroke. However, prospective controlled trials with a large sample size are needed.67 Conclusion IAB has a largely overlooked pandemic incidence in hospitals, both in- and out-patient settings, with numerous and remarkably significant elements. While identifying IAB is not difficult or complicated Inhibitors,research,lifescience,medical as compared to other ECG abnormalities, it is largely unrecognized, even with reading by ECG computers. As was demonstrated above, the prevalence of IAB is remarkably high in general Inhibitors,research,lifescience,medical hospital populations. Many institutions and investigators, therefore, use P-wave durations ≥120 milliseconds

to identify IAB. Is the standard criterion for ECG diagnosis of IAB (P-wave duration ≥110 milliseconds) inaccurately defined? Since the prevalence of IAB is high, and the standard criterion for ECG diagnosis differs among investigators, it is reasonable for the criterion for IAB to be re-evaluated to set a clinically relevant standard. Inhibitors,research,lifescience,medical However, this has to be established after studies show that a potential increase in the threshold can make a significant difference for further management, with confirmed specificity and sensitivity. Regardless, the standard criterion for ECG diagnosis should be set to a level of relevance where clinicians acknowledge the diagnosis Inhibitors,research,lifescience,medical and follow-up for further investigation. The emphasis on work-up in these patients can potentially prevent future cardiovascular outcomes. Similar to determining other important ECG criteria with modern epidemiologic studies, epidemiologic data for IAB should also be made available and taken into consideration,

evaluating the full 12-lead ECG Inhibitors,research,lifescience,medical to detect the true maximum P-wave duration and P-wave morphology, which increases sensitivity with the number of leads used. Consequently, the importance of multitrials detecting the cut-off values of IAB and risk should be underscored. Mephenoxalone Although the clinical consequences of IAB may be grave, absence of sufficient epidermiologic investigations and controlled trials means that no guidelines can be constructed for managing IAB patients. Do these patients need immediate treatment (i.e., ACEI, anticoagulation, and/or antiarrhythmic therapy?) If so, should it be prophylactic, anticipating atrial arrhythmias, i.e., anticoagulation? While such investigations are needed, electrophysiologic studies are inconvenient, costly, and unsuitable as a screening tool among the general population. Clinically, the ECG is an excellent diagnostic tool for demonstrating abnormal interatrial conduction.
