by the conduction abnormality. • The ST segment and T wave are both ab-normal and deviate in the same direction, ie, the ST segment is down-sloping and the T wave is inverted in leads with an up-right QRS complex, which gives the ST-T complex a “reverse checkmark” asymmet-

quence of repolarization, resulting in ST-T wave abnormalities. The direction of the ST-T wave abnormalities is usually oriented op-posite to the vectors of the delta wave and QRS complex. Because of the altered sequence of ventric-ular activation in WPW syndrome, the ECG may mimic other conditions and thus is oc-casionally overlooked or ...

Background: Nonspecific ST and T wave abnormalities (NSSTTA) on resting ECGs are associated with increased cardiovascular risk, and portend similar hazard ratios to traditional risk factors, such as dyslipidemia, hypertension, and diabetes mellitus (DM). Although NSSTTA are …

The ST segment and T wave of a repolarization abnormality following the QRS of a right bundle branch block or delay has a very unique and distinctive appearance. The ST segment demonstrates a slow descent from the J point. On occasion, the

Finally, myocardial infarction also causes the T wave to be inverted since it is repolarized in the opposite electrical direction (see Figure R3). Wolfe-Parkinson-White Syndrome The effects of this syndrome as seen in the EKG are clear in that the P-R interval is shortened and a deflection of the QRS interval, called the delta wave, is produced ...

Indeed, if the direction of the T wave is similar to that of the terminal part of the QRS complex (Fig. 5.14C), it should be considered abnormal. Such T-wave changes are primary and imply myocardial disease. The diagnosis of myocardial infarction in the presence of BBB is considered in Chapter 10 (“Myocardial Infarction”). Figure 5.14.

Abnormal repolarisation manifested by resting ST depression and T wave inversion is seen normally in LBBB in leads where the dominant deflection is a tall R wave (ST elevation is seen in leads where the dominant deflection is a deep S wave) and this depression routinely increases during exercise; as such the presence of LBBB precludes accurate ...

If a T wave in any one or more of these leads (I, II, V5, V6) is inverted/flipped/negative, then we call this Nonspecific T wave changes. For example: But what does this really mean to the patient. In other words, what kinds of problems will shift the T wave axis outside its normal range? Well, as you might guess from the title “nonspecific ...
