Echocardiographic parameters before CRT implantation.
| Electrocardiography | |
| QRS (ms): initial post CRT implantation |
160 (160–200) 130 (120–140) |
| Episodes of ventricular tachycardia | 13 patients (27.08%) |
| Atrial fibrillation | 9 patients (18.75%) |
| Echocardiographic Parameters | Mean (min–max) |
| LAV (mL) | 101.5 (83.25–142) |
| LVEDV (mL) | 236.5 (200–296.25) |
| LVEF (%—Simpson) | 26 (20.25–30) |
| LV-GLS (%) | 5.85 (3.82–7.2) |
| LV-PLS (%) | 5 (2.125–8) |

Legend: CRT—cardiac resynchronization therapy; LAV—left atrial volume; LVEDD—left ventricular end-diastolic volume; LVEF—left ventricular ejection fraction; LV-GLS—left ventricular global longitudinal strain; LV-PLD—left ventricular postero-lateral strain; TAPSE—tricuspid annular plane systolic excursion; sPAP—systolic pulmonary artery pressure.
