WebThe memory T waves can be seen in conditions such as correction of LBBB, ventricular tachycardia, pre-excitation, and sustained RV pacing. Discussion Cardiac memory refers to persistent T-wave changes that develop after a period of abnormal ventricular activation (wide QRS complexes), once ventricular depolarization changes.

WebPacemaker constraints in terms of sensing of fast low-amplitude signals are less than those of a defibrillator (necessity to sense and treat ventricular fibrillation). On the other hand, the oversensing of a cardiac (T wave, P wave) or extracardiac (myopotential, interference, etc) signal can be extremely problematic in pacemaker-dependent ...

Web1 jul. 2024 · The precordial T-wave changes seen on his ECG were attributed to cardiac memory following his intermittent LBBB. In a study looking at patients with intermittent LBBB, the incidence of TWIs seen during normal conduction was 72% and approximately half of those patients had no clinical evidence of coronary artery disease (6). WebThe cardiac memory effect usually depends on how long the heart was paced, and can last anywhere from a few hours to many weeks. Frequently, the T-wave following the pacing appears inverted. This is commonly referred to as T-wave inversion, or TWI. A similar TWI effect is frequently observed in ischemic patients.
