Observational StudyFragmented QRS may predict postoperative atrial fibrillation in patients undergoing isolated coronary artery bypass graft surgery.
Fragmented QRS complexes (fQRS) are defined as various RSR' patterns in 2 contiguous leads corresponding to a major coronary artery territory. Although the reason of association between fQRS and cardiac events was documented as cardiac fibrosis, the predictive role of fQRS was not studied for postoperative atrial fibrillation (POAF) which is a frequent and serious complication in patients undergoing isolated coronary artery bypass graft (CABG) surgery. Therefore, this issue was investigated in the present study. ⋯ In our study, we found that new-onset POAF was independently related to the presence and number of fQRS in patients undergoing CABG surgery. In addition, fQRS on pre-op surface ECG had high predictive values for new-onset POAF.

Comparative StudyAssessment of agreement between transthoracic and transesophageal echocardiography techniques for left ventricular longitudinal deformation imaging and conventional Doppler parameters estimation: a cross-sectional study.
Studies investigating the comparison and interchangeability of transthoracic (TTE) and transesophageal echocardiography (TEE) regarding left ventricular (LV) systolic and diastolic function are limited. Therefore, in this study, we aimed to investigate agreement between TTE and TEE in the assessment of LV systolic functions by longitudinal myocardial deformation imaging (strain-S and strain rate-Sr) and LV diastolic functions by conventional Doppler parameters. ⋯ TTE and TEE conventional Doppler parameters are compatible in the assessment of LV diastolic function; however, agreement was poor in longitudinal deformation parameters that have been used in the quantitative assessment of LV systolic function between two methods and cannot be used interchangeably.
