sup] Our case report showed in young patients, how this disease may present at the beginning with acute right heart failure, without ventricular arrhythmias but with episodes of symptomatic bradycardia that require the reconstruction of pulmonary valve and use of cardiac resynchronization therapy to avoid the well-known, long-term adverse effects of the right ventricular pacing
Infulence of right ventricular stimulation site on left ventricular function in atrial syncronous ventricular pacing
Atropine or isoproterenol is indicated in symptomatic cases until temporary ventricular pacing
This algorithm ensures that an atrial impulse detected by the ventricular channel immediately after the atrial impulse does not inhibit ventricular pacing
Beta-adrenergic receptor-G protein-adenylate cyclase complex in experimental canine congestive heart failure produced by rapid ventricular pacing
With a bundle branch block or in the situation of right ventricular pacing
the message only gets to one side of the heart and slowly gets to the other side.
The wire study can be used to exclude sinus tachycardia with first-degree block by careful comparison of RP and PR intervals during atrial and/or ventricular pacing
The Confient is designed to reduce unnecessary right ventricular pacing
, the company said.
All of these changes suggest either an accelerated ventricular escape rhythm or ventricular pacing
The survey indicates a similar lack of awareness about published guidelines for heart failure (44% of cardiologists, 47% of noncardiologists), a similar belief in left ventricular pacing
as a life-extending measure (44% of cardiologists, 41% of noncardiologists), and a similar level of uncertainty about when to refer a patient to hospice care (52% of cardiologists, 53% of noncardiologists).
Right ventricular pacing
can produce asynchronous ventricular activation that can have a negative inotropic effect.
Compared with single-chamber ventricular pacing
, stroke volume and cardiac output are increased and central filling pressures reduced .
