The T wave is even more susceptible to a variety of influences than the ST segment and thus is less reliable as a marker of pathological or physiological derangement since the majority of T-wave abnormalities are nonspecific. The T-wave axis in the frontal plane may differ from the QRS axis...
如果心电图显示部分数值在正常范围边缘，但仍可视为大致正常，如出现左心室肥大的最小电压值，可能是因为正常的变异。用英文描述可能包括“Nonspecific T wave abnormality”或“Left ventricular hypertrophy with repolarization abnormality”，这意味着轻微的心室肥大和复极异常可能在正常范围内。对于陈旧性下壁...
However, it should not exceed one-fourth the height of the R-wave or one-fourth the depth of the Q-wave if the Q wave is larger than the R-wave (Detweiler and Homberger, 1986). The term “nonspecific T-wave changes” is often used for those instances in which the morphology, ...
This includes infarction causing an abnormality of repolarization that leads toT waveinversion. El infarto causará una anomalía de la repolarización que provocará la inversión de laonda T. Literature “The EKG shows only nonspecific changes—a fewT waveinversions. ...
8. 8. Crossing between R and T, in the sense of the given definition, reveals a minor, nonspecific abnormality of the positive T wave. It represents an early sign of disturbed correlation within the ventricular complex and indicates initial stages of an abnormal condition of the ventricular ...
Conclusion: Isolated apical left ventricular hypertrophy should be considered as a possible cause of marked T-wave inversion in the precordial leads; this special form of hypertrophic cardiomyopathy is rarely seen in Europeans. As autosomal dominant inheritance of this condition has been described in ...
Episodes of ST segment elevation or T wave inversionalone were considered nonspecific . All ischemic episodeswere verified by two observers . The ambulatory ECG wasconsidered positive if at least one ischemic episode waspresent . A quantitative estimate of ischemia was made fromthe sum of the areas...
148 There may be an undescribed abnormality in MPS cell membranes resulting in the binding of fibrinogen and a calcium-independent form of spontaneous platelet aggregation. Electron microscopy of MPS platelets revealed increased volume, but nowhere near the size of MHA or ES platelets (Figs 32.37 ...
Nonspecific T wave abnormality）② 出现左心室肥大的最小电压值（Minimal voltage criteria for LVH（left ventricular hypertrophy）），可能是正常范围的变异（may normal variant）；大致正常心电图通过英文提示为：左心室略有肥大合并异常复极（Left ventricular hypertrophy with repolarization abnormality）...
