144 Can clinical examination and ecg predict a normal echocardiogram in patients presenting with palpitations – a single-centre experience

Introduction Palpitations are a common cause of referral to cardiology clinics for specialist assessment. Although some patients experience true arrhythmias, many have benign ectopic beats only. Echocardiography is routinely performed in such patients, but whether it required all with palpitations unknown. Purpose To analyse the echocardiographic findings presenting and assessing relation normal echocardiogram physical examination & resting 12 lead ECG. Methods In this single-centre retrospective study, we first obtained list seen electrophysiology (EP) clinics. Patients known arrhythmia structural heart disease were excluded, as whose complaint was not (figure 1A). Of remaining analysed notes clinic letters exam 12-lead ECG reports also. A defined by sinus rhythm P-QRS-T waves intervals. biventricular function, chambers sizes, valvular morphology function (including mild mitral tricuspid regurgitation). Results Over months, 1152 our EP clinics, whom 207 (18.4%) new no cardiac disorders(figure total 184/207 (89%) had echocardiograms. Physical documented 63% 93%. found 66%. Echocardiographic abnormalities 62 patients. 74 that both ECG, 57 (77%) – increased 82% (45/55) excluding hypertension or diabetes. Normal significantly correlate (73% (p<0.001)) 76% (P=0.022) respectively) (Table 2). The most dilated left atrium (74%), ventricular systolic dysfunction (18%), hypertrophy (16%) 1B). Conclusion without cardiovascular who present palpitations, rare Routine requesting echocardiography may be warranted role focussed should investigated further. Conflict Interest none
