The objective of the work was to compare the use of two types of long-term ECG monitors in examinations of @entity943 and to find out whether their yields differed significantly when @entity1 with a history of palpitations and @entity1163 are examined. Two recorders, King of Heart with manual operation of the ECG tracing were used and the R test with continuous recording of the ECG tracing. For statistical processing contingence tables were used. For examination by the King of Heart recorders 111 @entity1 (40 @entity1 and 71 @entity1 ) were indicated, average age 48 years (14-84 years). 108 @entity1 were examined. Yield I (number of @entity1 with complaints)--89%. Yield II (number of @entity1 with pathological ECG)--50%. In indications for palpitation pathological findings were recorded in 52% @entity1 . In indication for @entity1163 or presyncope pathological findings were recorded in 46% @entity1 . Yield II in these two groups does not differ significantly (p = 0.9). For examination with an R test recorders 74 @entity1 (30 @entity1 and 44 @entity1 ) were indicated with a mean age of 52 years (18-85). Yield I (number of @entity1 with complaints)--66%. Yield II (number of @entity1 with complaints and a pathological ECG)--40%. Yield III (total number of pathological ECG findings)--79%. Yield IV (number of @entity1 without complaints with a pathological ECG)--29%. In indication on account of palpitation there were pathological findings in 69% @entity1 . In indication on account of @entity1163 and presyncope pathological findings were recorded in 71% @entity1 . Yield II does not differ significantly in these sub-groups (p = 1.0). Statistical comparison of the yield of the two instruments: in the basic indication on account of palpitation the yield of these methods does not differ significantly (p = 0.09). In the basic indication on account of @entity1163 and presyncope the yield of the two methods does not differ significantly (p = 0.33). CONCLUSION: The yield of the two instruments for long-term Holter monitoring does not differ significantly, both can be recommended for examination of @entity1 with suspected @entity943 . The future belongs to instruments with continual ECG recording because of detection of asymptomatic @entity943 .
