Intraventricular conduction defects.
DESCRIPTION A 62-year-old woman with ischaemic heart disease reported having dyspnoea, chest pain in the left hemithorax, epigastric pain and nausea for 4 weeks. The patient’s blood pressure was 150/90 mmHg and ejection-fraction on echocardiography was 30–35%. An electrocardiogram showed a regular rhythm, with a widened QRS complex in all leads. There were notched R waves in V5, V6, aVL, II, II...
متن کاملPostoperative Intraventricular Conduction Defects
Intraventricular conduction defects are common following repair of various forms of congenital heart disease. Such defects may affect adversely the long-term prognosis of patients in whom cardiac hemodynamics were adequately restored. Review of previously published studies suggests that the site of the conduction defect may be the reason for the different prognoses reported for patients from di...
متن کاملIntraventricular conduction defects in acute myocardial infarction.
Of 325 consecutive cases with acute myocardial infarction admitted to a coronary care unit, II3 per cent developed one or more intraventricular conduction defects as an early, and often transient complication. The most common Lintraventricular conduction defect was block of the anterior fascicle, followed by complete right bundle-branch block, and by the association of right bundle-branch block...
متن کاملInitial ventricular activation in left-sided intraventricular conduction defects.
Nine patients with ECG evidence of rate-related left bundle branch block (LBBB) were studied using His bundle electrograms, electrograms from the right ventricular (RV) apex and vectorcardiograms recorded as heart rate was increased to produce LBBB. In five patients, when LBBB occurred, initially normal septal activation reversed and the HV intervals increased 10-30 msec, while the H-RVA interv...

or by rapid atrial pacing. Activation times were measured with intracardiac electrode catheters positioned at the right ventricular inflow tract (RVIT), right ventricular apex (RVA), right ventricular outflow tract (RVOT), left ventricular apex (LVA) and left ventricular outflow tract (LVOT). The activation after beginning of QRS in milliseconds ± 1 SD and the number of patients studied at each...
