Case	Disease	Sex	Age (years)	SBP	DBP	HR	ECG	MPAP	DWI	PVDW	TPSE	RVEF
Disease: 0, no heart disease; 1, pulmonary disease; 2, dilated cardiomyopathy; 3, hepatic cirrhosis and tricuspid regurgitation; 4, atrial septal defect; 5, systemic hypertension; ECG: 1, normal; 2, right ventricular overload; 3, left ventricular overload; 4, left bundle branch block; 5, block of previous division of left bundle branch; 6, anteroseptal Q wave.
DBP, diastolic blood pressure (mm Hg); DWI, D wave integral (mm); F, female; HR, heart rate (beats/min); M, male; MPAP, mean pulmonary artery pressure; RVEF, right ventricular ejection fraction; SBP, systolic blood pressure (mm Hg).
