Results of multivariable Cox proportional hazards analysis, performed to evaluate the association of tricuspid annular plane systolic excursion (TAPSE) on time to cardiac death when controlling for the effect of other measured variables. Reduced TAPSE lost statistical significance when patients had R‐on‐T phenomenon detected on Holter, but did demonstrate a significant association with shorter survival time when controlling for the presence of congestive heart failure (CHF) and detection of ventricular tachycardia (VT)
| Parameter | Hazard Ratio | 95% Confidence Intervals | P Value | |
|---|---|---|---|---|
| Model 1 | TAPSE <15.1 mm | 4.09 | 1.15–14.5 | .029 |
| ARVC diagnosis | 5.18 | 1.43–18.7 | .012 | |
| Model 2 | TAPSE <15.1 mm | 4.64 | 1.27–16.9 | .02 |
| CHF (yes) | 3.21 | 1.11–9.29 | .031 | |
| Model 3 | TAPSE <15.1 mm | 4.37 | 1.23–15.5 | .023 |
| LV systolic dysfunction | 3.69 | 0.81–16.9 | .093 | |
| Model 4 | TAPSE <15.1 mm | 4.36 | 1.22–15.6 | .023 |
| VT detected | 4.05 | 1.54–10.7 | .005 |
