Treatment Of Acute Pulmonary Thromboembolism Before And After The Clinical Analysis Of ECG Changes

Objective:Pulmonary thromboembolism (pulmonary thromboembo-lism, PTE) for the right heart from the venous system or thrombotic occlusion of pulmonary artery and its branches caused by the disease, with pulmonary circulation and respiratory dysfunction, its main clinical and pathophysiological features. Pulmonary embolism (pulmonary embolism, PE) of the most common type, accounting for the vast majority of PE, often called PE i.e. PTE. Pulmonary artery obstruction caused by acute PTE, can cause pulmonary hypertension and right ventricular loading increased, to some extent lead to decompensated right heart, right heart dilatation, acute pulmonary heart disease. Reduce pulmonary artery obstruction or after reperfusion, pulmonary hypertension and right heart systems change can improve. Through retrospective analysis of 60 cases of acute pulmonary embolism in patients with ECG changes before and after treatment the clinical data of PTE ECG changes and changes in ECG characteristics before and after treatment, raising awareness of pulmonary embolism diagnosis and treatment and outcome of cases followed up.Clinical Data and Research Methods:A retrospective analysis of the First Affiliated Hospital of Dalian Medical University,5 years (Jan.2006-Dec.2009) of 60 hospitalized patients with acute pulmonary embolism in patients with clinical data, including gender, age, general information. Not associated with chronic respiratory diseases, and connective tissue disease. All the patients were spiral CT pulmonary angiography (Computed tomography pulmonary angiography, CTPA) and confirmed. Analysis of the performance of their admission electrocardiogram and thrombolytic anticoagulant or anticoagulant therapy compared ECG 15 days later. SPSS 16.0 software was used, the measurement data using tests testing method, count data using X2 test. P<0.05 statistically significant.Results:60 cases of acute pulmonary thromboembolism(1) admission, the majority of electrocardiogram have different degrees of change, in which sinus tachycardia in 56 cases (68.29%); right bundle branch block in 19 cases; typical Sâ… Qâ…¢Tâ…¢only 25 cases, accounting for 41.67%; Qâ…¢Tâ…¢58 cases; Qâ…¢69 cases; Sv1-v5R setback of 43 cases of crude blunt; TV1-V2 inverted 64 cases, TV1-V3 inverted 51 cases, TV1-V4 inverted 48 cases, TV1-V5 inversion of 32 cases, TV1-V6 upside down in 17 cases,(2) ECG changes after thrombolytic therapy:35 cases of sinus tachycardia disappeared; the right Bundle branch block disappeared in 13 cases; S1shallow, Qâ…¢decreased or disappeared, Tâ…¢inversion changes 41 cases of superficial or upright; SV1-V5 crude blunt frustration disappeared in 11 cases; precordial T wave shallow Or vertical in 17 cases; T wave inversion deepened or inverted vertical change of 24 cases.(3) prior to discharge ECG changes:tachycardia disappeared, Qâ…¢further decreased or disappeared, Tâ…¢shallow or vertical, upright precordial T wave increase in the number.Conclusion:ECG manifestations of acute pulmonary embolism varied, dynamic and combine the clinical observation Change as an important indicator of disease.
