Think Beyond Right Bundle Branch Block in Atrial Septal Defect
475 The Editor, A 48‐year‐old woman presented with shortness of breath on routine activities for 6 months. On cardiac auscultation, an ejection systolic murmur was heard at the upper left sternal border with wide and fixed splitting of the second heart sound. Electrocardiogram (ECG) was suggestive of normal sinus rhythm with right‐axis deviation, incomplete right bundle branch block (RBBB), and...
متن کاملFurther observations on the etiology of the right bundle branch block pattern following right ventriculotomy.
Fifteen patients with various congenital heart defects were studied during open heart surgery in order to establish the precise mechanism by which a right ventriculotomy causes a right bundle branch block (RBBB) pattern on the scalar electrocardiogram (ECG). All required a right ventriculotomy for the correction of their defects. In each, the right ventriculotomy was carried out in steps, with ...
متن کاملCardiac resynchronization therapy for heart failure induced by left bundle branch block after transcatheter closure of ventricular septal defect
A 54-year-old female patient with congenital heart disease had a persistent complete left bundle branch block three months after closure by an Amplatzer ventricular septal defect occluder. Nine months later, the patient suffered from chest distress, palpitation, and sweating at daily activities, and her 6-min walk distance decreased significantly (155 m). Her echocardiography showed increased l...
متن کاملRight ventricular hypertrophy and right bundle branch block.
Wit/i the collaboration of Charles A. Bertrand, M.D., and Frederick R. Mugler, M.D. Electrocardiographic and vectorcardiographic studies on normal subjects and patients with heart disease suggest that criteria for the diagnosis of right ventricular hypertrophy can be improved and simplified. This report proposes new criteria for the electrocardiographic diagnosis of right ventricular hypertroph...
متن کاملRight bundle-branch block ventricular tachycardias: septal versus lateral ventricular origin based on activation time to the right ventricular apex.
BACKGROUND Identifying the septal versus lateral site of origin of ventricular tachycardia (VT) with a right bundle-branch block (RBBB)-type pattern and an R-S ratio >1 in lead V1 is difficult with the 12-lead ECG, especially in patients with prior apical infarction. METHODS AND RESULTS We prospectively evaluated 58 patients with VT. Sixteen patients had apical infarcts (group 1), 29 had nona...
