Reversible intraventricular conduction defect in aconitine poisoning.
Chinese medicine plays an important role in providing medical care for people in countries with large Chinese communities, including Hong Kong. The aconite herb is one of the commonly-prescribed ingredients for various clinical problems. However, due to its narrow therapeutic index, toxicities are not uncommonly encountered, including life-threatening cardiac arrhythmias like ventricular arrhyt...

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...

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 کاملIntraventricular Conduction Delay
Re-entry within the atrioventricular (A-V) node is a common cause of atrial echo beats and paroxysmal atrial tachycardia. This report deals with observations made in four patients in whom the determining factor for atrial echo beats appeared to be a critical conduction delay occurring within the His-Purkinje system and not within the A-V node. The evidence in support of this conclusion is as fo...
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...
