A case of portopulmonary hypertension characterized by repeated syncope was retrospectively analyzed. Intrahepatic or extrahepatic factor-induced portal hypertension complicated with metabolic disorder of vasoactive substances, vascular pressure, inflammation, etc. may result in systolic and diastolic dysfunction of pulmonary arteries and systemic hyperdynamic circulation, the long-term effect of which can induce vascular remodeling and consequently, pulmonary hypertension. The pathogenic process is rather insidious. Pulmonary hypertension is clinically characterized by the raised average pulmonary artery pressure, normal pulmonary capillary wedge pressure and high pulmonary vascular resistance. Currently available therapeutic approaches include drug therapy targeting on pulmonary hypertension and liver transplantation.

In order to assess the diagnostic value of invasive electrophysiologic study (EPS) in the patients with unexplained syncope, the electrophysiologic findings of 268 patients with unexplained syncope despite a complete clinical evaluation were analyzed. Results showed positive EPS finding was 38% in total patients and 50% in the patients aged > 70 years. With increasing age, the diagnostic yield of EPS also increased. No significant differences of complication rate were found among the different age groups. It was concluded that EPS have high diagnostic value in the patients with unexplained syncope. Its complications are few and mild. EPS may be recommended in elderly patients with unexplained syncope.

OBJECTIVEThis study aimed at analyzing the usefulness of a modified Calgary Syncope Syndrome Score in the differential diagnosis between cardiac syncope (CS) and vasovagal syncope (VVS) in children through a large sample clinical study.

METHODTotally 189 children [112 males, 77 females, aged 2 - 18 yrs, mean age (12.4 ± 3.1) yrs] with CS and VVS who were at the syncope clinic or admitted to the Department of Pediatrics, Peking University First Hospital from August 2002 to April 2011 were included in the study. The diagnosis was analyzed by a modified Calgary Syncope Syndrome Score and receiver operating characteristic (ROC) curve was used to explore the predictive value of different Calgary Syncope Syndrome Scores in differential diagnosis between CS and VVS.

RESULTThere were significant differences in the score between CS [-5.00(-7, 1)] and VVS [1(-4, 6)] (P < 0.01). When the score was ≤ -2.5, the sensitivity and specificity of the differential diagnosis between CS and VVS were 95.4% and 67.7%, respectively. Since the modified Calgary Syncope Syndrome Score was integer number, CS should be considered when the score was less than -3.

CONCLUSIONThe modified Calgary Syncope Syndrome Score might be used as an initial diagnostic method in differential diagnosis between CS and VVS, based on the history of the patients.

OBJECTIVESTo explore the clinical characteristics of cardiac syncope (CS) in children, and understand their significance in predicting the cardiac syncope.

METHODSTwenty-three patients were referred to our department for evaluation of syncope. The diagnosis of the above cases was cardiac syncope. Each patient was interviewed using a standard questionnaire. The clinical histories and standard baseline electrocardiogram were analyzed to identify the variables contributing to the diagnosis of CS in children.

RESULTSA cardiac cause was identified in 23 syncopal patients presenting to the Department of Pediatrics, Peking University First Hospital: sick sinus syndrome in 7, congenital long QT syndrome in 4, third degree atrioventricular block in 2, supraventricular tachycardia in 2, ventricular tachycardia in 1, atrial fibrillation in 1, pacemaker dysfunction in 1, idiopathic pulmonary hypertension in 3, hypertrophic cardiomyopathy in 1, and dilated cardiomyopathy in 1. The average age of CS patients was 9 years. In totally 23 patients, exertion related syncope spells were found in 14 cases (60.9%), syncope spells at various position 7/23 (30.4%), absence of prodromes in 12/23 (52.2%), syncope spells with incontinence in 4/23 (17.4%), history of heart disease in 4/23 (17.4%). Abnormal standard baseline electrocardiogram was found in 21 cases (91.7%).

CONCLUSIONSThe children with cardiac syncope have overt clinical features, especially abnormal findings in electrocardiogram and exertion related syncope spells are the most common clinical features.
