[Electrocardiographic Holter monitoring in XXXX with ventricular pre-excitation: possibilities of its uses and pitfalls].

@entity1 @entity3155 @entity1540 @entity4710 @entity943
Holter monitoring (HM) of the electrocardiogram (ECG) is used currently for the management of @entity1 with ventricular @entity3155 ( @entity3155 ). It makes it possible to detect inconstant @entity3155 which is considered a marker of a favourable clinical development. HM of ECG is not suitable for the detection of @entity4710 ( @entity4710 ) in @entity1 with @entity3155 , as their presence is detected only exceptionally during HM. It can be used for the detection of other disorders of the cardiac rhythm than @entity4710 , in particular in supraventricular and @entity1540 (SVES and VES). Frequent SVES and VES detected during HM can as potential triggers of @entity4710 indicate a higher risk of these @entity943 . HM is used for the objectivization of relatively frequent, sometimes quite polymorphous subjective complaints of @entity1 with @entity3155 . Subjective data of these @entity1 are very unreliable and from these data it is not possible to draw conclusions on the presence or absence of disorders of the cardiac rhythm. HM of ECG is not a suitable method for the evaluation of the effectiveness of medicamentous antiarrhythmic treatment of @entity4710 because of their considerable spontaneous variability. It may be, however, used partly for the evaluation of success of radiofrequency ablation treatment. Evaluation of long-term ambulatory ECG Holter tracings in @entity1 with @entity3155 is more complicated and more time consuming than in subjects without @entity3155 . In any case it is essential that the record should be evaluated by an experienced physician with sufficient knowledge in arrhythmology.
