One patient required a permanent pacemaker for sinus node dysfunction
and a persistently prolonged [QT.
The exercise can also assess the type and severity of sinus node dysfunction present, based on the heart rate and rhythm response to the stress.
Certain endocrine problems, most commonly hypothyroidism (underactive thyroid), can imitate sinus node dysfunction, and therefore blood tests to assess the thyroid are usually performed in the workup
In the standard group implantable cardioverter defibrillator (ICD) implantation was applied to one patient due to the sinus node dysfunction the permanent pace and to one patient due to the ventricular tachycardia attacks.
Sinus node dysfunction is one of the reasons of morbidity after orthotopic heart transplantation.
The 70-year-old patient had sinus node dysfunction
Similarly, during RCA percutaneous interventions, distal embolization of plaque components after balloon inflation and stent implantation may cause sinus node dysfunction
, severe bradycardia, which are mostly expected to occur during proximal RCA interventions as a consequence of plaque shifting into a proximally located SAN artery.
Lexiscan should not be administered to patients with second- or third-degree AV block or sinus node dysfunction
who do not have a functioning artificial pacemaker.
Indications for pacing included atrioventricular block in 76% and sinus node dysfunction
in 22% patients.
ECRI published its systematic review as a Windows on Medical Technology(TM) evidence report in March 2005: "Dual-Chamber versus Single-Chamber Pacemakers for Sinus Node Dysfunction
and Atrioventricular Block.
Sinus node dysfunction
had its own image on the RCGm--there were supracompensative pauses after extrasystole, Wenckebach's or Mobitz's periodics.
Kuck implanted the dual-chamber rate-responsive Integrity(TM) Micro AutoCapture(TM) Pacing System DR (Model 5336) in a 77-year old male patient with first-degree AV block and sinus node dysfunction
