Biventricular pacing in a patient with ventilatory and inotropic dependant heart failure following coronary artery by-pass surgery.
Resynchronisation of intra- and interventricular conduction delay by biventricular pacing has become a proven therapy for selected heart failure patients. We present a case of biventricular pacing, used with great success, as a 'bail out' for a patient with refractory congestive heart failure following by-pass surgery.
متن کاملIs Cardiac Resynchronisation Therapy Proarrhythmic?
It is well established that cardiac resynchronisation therapy (CRT) using biventricular pacing prolongs survival by its effects on pump failure. The rate of sudden cardiac death in patients undergoing CRT, however, remains high. Animal and human studies have shown that reversal of normal sequence of myocardial activation during epicardial pacing, as applied during CRT, increases the transmural ...
متن کاملSelection and optimisation of biventricular pacing: the role of echocardiography.
The quantification of ventricular dyssynchrony is a key factor in identifying patients with severe heart failure who may benefit from cardiac resynchronisation with biventricular pacing (BVP). Echocardiographic techniques appear to offer superior sensitivity and specificity than the ECG in selecting these patients. This paper reviews the scope of current echocardiographic techniques for guiding...
متن کاملMechanical resynchronisation in biventricular pacing illustrated by real time transthoracic three dimensional echocardiography.
A 74 year old man with dilated cardiomyopathy and right bundle branch block underwent implantation of a biventricular pacemaker for treatment of severe heart failure. When reviewed six weeks later his New York Heart Association functional class had improved from III to I. Using the Sonos 7500 Live 3D system, a real time transthoracic three dimensional echocardiogram was performed in the presenc...

متن کاملCLINICAL REVIEW Cardiac resynchronisation therapy for chronic heart failure
Chronic heart failure is common, affecting about 900 000 people in theUnited Kingdom andwith a prevalence of about 6-10% in people aged over 65 years; despite modern drug treatment, it carries a high morbidity and a 10% annual mortality. About a third of patients with chronic heart failure have a left ventricular ejection fraction ≤35%, up to 40% of whom are at risk of worse outcomes and more s...
