The Characteristic Of Electrocardiogram In Patients With Acute Pulmonary Embolism And Electrocardiogram Scoring System For Their Risk Assessment

Objective: Pulmonary thromboemboism(pulmonary thromboembolism,PTE)for theright heart from the venous system or thrombotic occlusion of pulmonary artery andits branches caused by the disease,with pulmonary circulation and respiratorydysfunction,its main clincal and pathophysiological features.Pulmonary embolism(plumonary embolism,PE)of the most common type,accounting for the vast majorityof PA,often called PE i.e.PTE.Pulmonary artery obstruction caused by acute PTE,cancaused pulmonary hypertension and right ventricular loading increased,to some extentlead to decompensated right heart,right heart dilatation,acute pulmonary heartdisease.Reduse pulmonary artery obstruction or after reperfusion,pulmonaryhypertension and right heart systems change can improve.Through retrospectiveanalysis of40cases of acute pulmonary embolism in patients with ECG changesbefore and after treatment the clinical data of PTE ECG changes and changes in ECGcharacteristics before and after treatment,raising awareness of pulmonary embolismdiagnosis and treatment and outcomes of cases followed up.Methods:1.Using retrospective analysis method selected consecutive in Fujian MedicalUniversity affiliated Quanzhou First Hospital heart medicine and in Department ofrespiration and the diagnosis of acute pulmonary embolism in40cases of patientswith the clinical data during2006September to2011November, including gender,age and other general information. The respiratory disease branch of Chinese MedicalAssociation developed pulmonary thromboembolism diagnostic and treatmentguidelines as diagnostic criteria, and all patients were confirmed by lung CT scanning (i.e.+enhanced spiral CT pulmonary angiography confirmed).2. For selected patients with synchronous12-lead ECG tracings conventional12-leadand right heart lead (V3R-V5R) electrocardiogram, and determination of serum Dtwo dimers, blood gas analysis, spiral CT pulmonary angiography, echocardiography,double extremity arteriovenous color Doppler ultrasound and other projects.3.40cases of patients according to the patients with pulmonary vascular congestiontruncated area40electrocardiograms were divided into2groups, the pulmonaryvascular obstruction area of more than50%for A group, a total of22electrocardiogram; less than50%of B group, a total of18electrocardiogram.4. Analysis the A and B in two groups of patients’s ECG with ECG scoring system.5.Analysis and compared all of the pulmonary vascular truncated area size andelectrocardiographic manifestations. Using SPSS16.0software statistical testingmethod, the measurement data test, count data by using the chi-square test. P <0.05,with statistical significance.Results：1. A total of40copies of the electrocardiogram,normal in15%, abnormal,85%;group A22, normal1, abnormal21; in18of group B, normal6, abnormal12.2. The abnormal electrocardiographic and electrocardiographic scores of Pulmonaryvascular obstruction area of more than50%persons’group are obviously higher thanthat of smaller group’s.Conclusion:The ECG changes of pulmonary embolism is pertaining to Pulmonary vascularobstruction area,and it is non-specific,Non-diagnostic and valuable,Correctapplication of these changes help to pulmonary embolism diagnosis.and ECG Danielscore size is positively correlated with pulmonary embolism vascular bed blockingsize,therefore it can help to assess the risk of pulmonary embolism in patients with.
