All figures quoted are for multivariate analyses of the predictive effect of transthoracic echocardiography.
IHD = Ischaemic heart disease. MR = Mitral Regurgitation. APO = Acute pulmonary oedema. VF = Ventricular fibrillation. CHB =
Complete heart block. MI = Myocardial infarction. VT = Ventricular tachycardia. CCF = Congestive cardiac failure. LV = Left
ventricular. LVH = Left Ventricular Hypertrophy. LVEF = Left Ventricular Ejection Fraction. POC = Post-operative complication. OR
= Odds ratio. CI = Confidence Interval. PPV = Positive Predictive Value. NPV = Negative predictive value
