Acute right ventricular dysfunction definition∗.
| Echo parameters | ECG signs | Biomarkers | |
|---|---|---|---|
| RV systolic function | RV dilation | ||
| TAPSE < 16 mm | ED RVD/LVD ratio > 0.9 | Complete RBBB | BNP > 100 pg/mL |
| S < 10 cm/sec | ED RVA/LVA ratio > 0.6 | Incomplete RBBB | NT-proBNP > 900 pg/mL |
| RV fractional area change < 35% | ED RVD > 42 mm (at the base) | Anteroseptal ST elevation | |
| RV ejection fraction < 45% | ED RVD > 33 mm (at the middle third of RV) | Anteroseptal ST depression | |
| Septal dyskinesia in the RV focused view | Anteroseptal T-wave inversion | ||
BNP: B-type natriuretic peptide; ED RVD/LVD ratio: end-diastolic RV diameter/LV diameter ratio; ED RVA/LVA ratio: end-diastolic RV area/LV area ratio; ED RVD: end-diastole RV diameter; NT-proBNP: N-terminal pro-BNP; S: pulsed Doppler S wave; TAPSE: tricuspid annular plane systolic excursion. ∗At least one of the items must be present (echo parameters, ECG signs, and biomarkers) [30].
