Electrical storm: Is right ventricular pacing dangerous?
Introduction: Electrical storm is commonly defined as the occurrence of three or more episodes of ventricular tachycardia (VT) or ventricular fibrillation (VF) in 24 hours. Patients with an implantable cardiac defibrillator (ICD) are at increased risk of electrical storm due to history of decreased ejection fraction and/or sustained VT/VF. In addition to medical treatment of electrical storm in...
متن کاملRight ventricular pacing for right ventricular outflow tract obstruction in a man with biventricular hypertrophic cardiomyopathy.
A 40-year-old man with known hypertrophic cardiomyopathy presented with syncope after coughing. Physical examination revealed a systolic murmur that was accentuated by the Valsalva maneuver. An electrocardiogram suggested biventricular hypertrophy and biatrial enlargement (Fig. 1). Echocardiograms revealed asymmetric septal hypertrophy with a diastolic septal thickness of 2.3 cm, and evidence o...
متن کاملEffect of right ventricular versus biventricular pacing on electrical remodeling in the normal heart.
BACKGROUND Biventricular (BIV) pacing can improve cardiac function in heart failure by altering the mechanical and electric substrates. We investigated the effect of BIV versus right ventricular (RV) pacing on the normal heart. METHODS AND RESULTS Male New Zealand White rabbits (n=33) were divided into 3 groups: sham-operated (control), RV pacing, and BIV pacing groups. Four weeks after surge...
متن کاملOptimal pacing for right ventricular and biventricular devices: minimizing, maximizing, and right ventricular/left ventricular site considerations.
The results from numerous clinical studies provide guidance for optimizing outcomes related to RV or biventricular pacing in the pacemaker and ICD populations. (1) Programming algorithms to minimize RV pacing is imperative in patients with dual-chamber pacemakers who have intrinsic AV conduction or intermittent AV conduction block. (2) Dual-chamber ICDs should be avoided in candidates without a...
متن کاملRight Apical, Biventricular and Right High Septal Ventricular Pacing: A Comparison of Procedural Burden and Long Term Electrical Performance
Background/Aims: It has previously been shown that permanent right ventricular (RV) apical pacing may lead to worsening of cardiac function due to associated electrical and mechanical dyssynchrony. Cardiac resynchronization therapy (CRT) or high septal RV pacing could be beneficial to prevent patients from these negative effects. Methods/Results: In this single center clinical study 164 patient...
