1/4. pulmonary edema after cardioversion for paroxysmal atrial flutter: left ventricular diastolic dysfunction induced by direct current shock.This report describes a patient with the pulmonary edema after cardioversion for paroxysmal atrial flutter without organic heart disease. A 68-year-old man was admitted to hospital for paroxysmal atrial flutter. Antiarrhythmic agents were not effective, and direct current cardioversion was performed on the 4th hospital day. Three hours after cardioversion, the patient complained of dyspnea, and a chest X-ray showed pulmonary edema. He responded to oxygen, intravenous furosemide and drip infusion of nitroglycerine. During tapering of the medication, his condition remained stable. The patient was discharged on the 7th day after admission. Echocardiographic findings indicated that transient left ventricular diastolic dysfunction due to direct current shock was the most likely cause of the lung edema.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
2/4. amiodarone-related optic neuropathy.BACKGROUND: To evaluate a case of atypical optic neuropathy that presented with blurred vision following the use of an antiarrythmic agent. CASE: Record of the patient was reviewed to determine the etiology of his optic neuropathy. OBSERVATIONS: Ophthalmological examination revealed unilateral optic disc edema with relatively well-preserved visual acuity. In routine tests, results of complete blood count, erythrocyte sedimentation rate, liver and kidney function tests, chest x-ray, Goldmann visual field examination, and brain computed tomography scan were normal. Orbital ultrasonography revealed optic disc edema with prominent optic nerve head and without orbital pathology. CONCLUSIONS: Systemic history and drug intake should be investigated in every patient with optic disc edema. Discontinuation of the medication can prevent further optic nerve damage or involvement of the other eye.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
3/4. Acute right coronary artery occlusion following radiofrequency catheter ablation of atrial flutter.Acute right coronary artery occlusion following radiofrequency ablation. We report the first known case of acute right coronary artery occlusion following Radiofrequency (RF) ablation for atrial flutter in a patient without known prior coronary disease. Our patient developed acute chest pain and inferior ST-segment elevation immediately following the procedure. Emergent cardiac catheterization was performed, revealing an occluded distal right coronary artery, which was immediately stented. Acute coronary occlusion should be considered in the differential diagnosis of patients, with or without coronary artery disease, who experience chest pain following RF ablation for atrial flutter.- - - - - - - - - - ranking = 23.970864087523keywords = chest pain, chest (Clic here for more details about this article) |
4/4. Body surface maps in 2 cases of atrial flutter.Body surface maps during one cycle of atrial flutter were recorded in 2 cases. The sequences of movements of the maximum and the minimum were compared to those of the sinus P waves. The maps of normal sinus P waves usually show that a maximum first appears at the anterior chest near the sternum and moves to the left side of the thorax in the later half of the P wave. The maps of atrial flutter in Case 1 showed that a maximum first appeared on the upper right back and then moved to the right side of the anterior chest. The maps of Case 2 showed that a maximum first appeared on the upper right back and then moved down the right side of the posterior thorax. There were no movements of the maxima in either case from the right side of the chest to the left as seen in the sinus P waves.- - - - - - - - - - ranking = 3keywords = chest (Clic here for more details about this article) |
