Cases with right ventricular (RV) dilatation: fulfilled criteria, clinical context.

Patient Nr	1 criterion fulfilled	2 criteria fulfilled	3 criteria fulfilled	Clinical context
11	No	No	No	No 24h-ECG, RV dilatation due to fluid overload
25	Yes	Yes	Yes	Progressive abdominal distention, ascites, dilatation of all 4 chambers, systolic dysfunction, moderate TR
35	Yes	Yes	Yes	Recurrent collapses, high arrhythmic burden, mild LV dilatation
56	Yes	Yes	Yes	Syncope during exercise, generalised cardiomegaly, sustained VT during follow up
101	Yes	Yes	No	SVT during routine examination, later presyncope, cough, moderate MR
102	No	No	No	Lethargy, dilatation of all 4 chambers, no 24h-ECG
136	Yes	Yes	Yes	Abdominal distention, ascites, chaotic arrhythmia incl. AF, rapid ventricular runs, severe TR, clinically interpreted as ARVC
155	No	No	No	Murmur at routine examination, syncope during excitement, severe AS, VT in 24h-ECG
222	No	No	No	Murmur detected at first vaccination, severe PS, TR, right heart failure

TR: tricuspid valve regurgitation; LV: left ventricular; VT: ventricular tachycardia; MR: mitral valve regurgitation; AF: atrial fibrillation; ARVC: arrhythmogenic right ventricular cardiomyopathy; AS: aortic stenosis; PS: pulmonic valve stenosis
