Echocardiographic findings in atrial flutter.
Echocardiographic studies were performed in 22 patients with atrial fibrillation and atrial flutter. In atrial flutter, the echocardiograms consistently demonstrated regular undulatory waves of the posterior left atrial wall and upper left interventricular septum coinciding with each flutter wave of the electrocardiogram. The mitral valve was slightly reopened by each flutter wave occurring aft...
متن کاملEchocardiographic demonstration of atrioventricular mechanical contraction in atrial flutter.
We present the case of a 54-year-old patient with no history of heart disease who underwent transesophageal echocardiography (TEE) to rule out the presence of thrombus in the left atrial appendage (LAA) prior to programmed electrical cardioversion for common counterclockwise atrial flutter with 2:1 ventricular response at 150 bpm. The TEE confirmed good biventricular function, no thrombus in LA...
متن کاملCardiocascular images. M-mode echocardiographic demonstration of atrial flutter.
In cases with narrow QRS-complex tachycardia, prompt differentiation of the etiology is crucial in management. M-mode echocardiographic examination of the interatrial septum can give important information in the emergency department. A 57-year-old man who had palpitation and dyspnea for 2 days visited our emergency department. The initial ECG showed negative saw-tooth–shaped atrial activity in ...
متن کاملElectrical remodeling of the atria associated with paroxysmal and chronic atrial flutter.
BACKGROUND Atrial electrical remodeling may be important for the initiation and perpetuation of atrial arrhythmias. Whether paroxysmal atrial flutter (AFL) and chronic AFL cause electrical remodeling of the atria has not been conclusively determined. METHODS AND RESULTS Before radiofrequency ablation of paroxysmal AFL, 15 patients in sinus rhythm were evaluated under autonomic blockade. Later...
متن کاملEchocardiographic Study
Background Standard mitral valve replacement (MVR) in patients with chronic mitral regurgitation results in consistent reductions in resting postoperative ejection fraction. This has been attributed to removal of the low-impedance ejection pathway into the left atrium or to disruption of the chordal apparatus. Mitral valve repair (MVP) does not reduce ejection fraction at rest. However, whether...
