Kn @entity1 with @entity5968 , episodes of transient @entity854 ( @entity854 ) are often documented in addition to the typical episodes of @entity1347 @entity1347 ( @entity1347 ). As the interpretation of these minor ECG changes is still uncertain, we investigated if transient @entity854 are associated with reversible @entity67 , similar to episodes with @entity1347 . For this purpose an ECG lead and a two-dimensional echocardiographic projection, which showed clear-cut changes during previous episodes of @entity1347 , were simultaneously monitored in five @entity1 with @entity5968 for a total of 13 hours and 20 minutes. In all @entity1 , the 30 episodes of @entity1347 recorded were all accompanied by reversible @entity67 . Furthermore, in four of these @entity1 , 14 episodes of @entity854 (peaking, flattening, or the appearance of a diphasic T wave) were recorded. All @entity854 were associated with reversible asynergies, as detected by three independent observers. The @entity73 occurred in the same ventricular wall both during @entity1347 and during @entity854 . During @entity854 the degree of @entity73 appeared less severe ( @entity2845 in 12 and @entity910 in two episodes) than during @entity1347 ( @entity2845 in one, @entity910 in 25, and @entity910 in four episodes) (p less than 0.001). The duration of asynergies was less during @entity854 (107 +/- 76 seconds) than during @entity1347 (169 +/- 83 seconds) (p less than 0.05). @entity662 was reported in 5 of 14 episodes of @entity854 (36%) and in 20 of 30 (66%) episodes of @entity1347 (p less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
