A comparison of the data computed tomographic angiography and echocardiography with classic electrocardiographic signs of pulmonary embolism the low risk of death.

Abstract

A study of the correlation of the ECG symptoms to echocardiographic and CT-angiographic of the symptoms of overload of the right heart in 87 patients with pulmonary embolism (PE) is not a high risk of death. All patients were hospitalized on the first day of development of pulmonary embolism. 35.6% of patients had ECG symptoms overload right heart: deep teeth S and Q negative T in V-V, signs of blockade of right bundle branch block. Most of these patients had occlusion of the lobar artery. And in patients without ECG symptoms ofpulmonary embolism were more often obstruction of the segmental arteries (p<0,01). ECG symptoms overload right heart was with the obstruction of two or more of the lobar artery or more than ten segmental arteries. Most patients with pulmonary embolism with ECG signs of overload of right departments of heart, source of embolism was veins of femoral-popliteal segment, and pulmonary embolism in patients without ECG symptoms source was sureline vein (p=0,03). A high correlation between ECG symptoms and amount of damage to the pulmonary system in CT-angiographic, ECG and EchoCG symptoms overload right heart. The same high correlation between the ECG signs of overload of the right heart and clinical symptoms: shortness of breath and presyncopal states.
