Polymorphic ventricular arrhythmia triggered by temporary epicardial right ventricular stimulation after cardiac surgery
Introduction Temporary epicardial pacing is commonly used for rhythmic support in the acute postoperative period after cardiac surgery. Clinical studies suggest that pacing in the left ventricular epicardium during resynchronization therapy may be proarrhythmic in a minority of patients. The epicardial pacing increases transmural heterogeneity of repolarization. This could prolong the QT and JT...
متن کاملVentricular aneurysms after cardiac surgery.
were left ventricular aneurysms, all of which occurred after the operation of closed or 'blind' aortic valvotomy in adults, and four were right ventricular outflow tract aneurysms which developed in children after surgical procedures for the correction of severe forms of Fallot's tetralogy. Two of the left ventricular aneurysms arose at the site of the ventriculotomy usedfor introducing the Bro...
متن کاملCardiac sympatho-vagal balance and ventricular arrhythmia☆
A hallmark of cardiovascular disease is cardiac autonomic dysregulation. The phenotype of impaired parasympathetic responsiveness and sympathetic hyperactivity in experimental animal models is also well documented in large scale human studies in the setting of heart failure and myocardial infarction, and is predictive of morbidity and mortality. Despite advances in emergency revascularisation s...
متن کاملCardiac fibroma resulting in fatal ventricular arrhythmia.
Apreviously well and asymptomatic 6-year-old boy collapsed at school. He was initially asystolic but was resuscitated to sinus rhythm. Then, during transport to the hospital, he developed monomorphic ventricular tachycardia (Figure 1). Transthoracic echocardiography demonstrated a huge, homogeneous intramural mass in the left ventricular free wall, possibly also involving the left atrial wall, ...
متن کاملEffects of local cardiac denervation on cardiac innervation and ventricular arrhythmia after chronic myocardial infarction
BACKGROUND Modulation of the autonomic nervous system (ANS) has already been demonstrated to display antiarrhythmic effects in patients and animals with MI. In this study, we investigated whether local cardiac denervation has any beneficial effects on ventricular electrical stability and cardiac function in the chronic phase of MI. METHODS Twenty-one anesthetized dogs were randomly assigned i...
