Sick sinus syndrome requiring permanent pacemaker implantation in a patient with mirror-image dextrocardia.
A patient with the sick sinus syndrome accompanying mirror-image dextrocardia which was associated with double superior venae cavae and an absent inferior vena cava is presented. A permanent transvenous demand pacemaker was inserted because of repeated episodes of dizziness and a documented 31/2-second period of asystole. Precise knowledge of the venous system and the location of the apex of the right ventricle was necessary prior to permanent pacemaker implantation.
Refractory reentrant atrial tachycardia. Successful treatment with a permanent radio frequency triggered atrial pacemaker.
This 68 year old man had recurrent episodes of paroxysmal atrial tachycardia, probably due to chronic pericarditis, persisting over a 7 year period. These episodes were resistant to all conventional medical therapy and at times produced ischemic chest pain. There was no evidence of Wolff-Parkinson-White syndrome either on the standard electrocardiogram or on the His bundle electrogram performed with atrial pacing. Rapid atrial pacing at a rate of 200/min was found to promptly terminate the tachycardia and restore normal sinus rhythm. Because of the refractoriness of the patient's tachycardia, in addition to the presence of ischemic chest pain during these episodes, a permanent radio frequency triggered atrial pacemaker was inserted which enables him to initiate rapid atrial pacing by pressing an external control. The patient has been maintained on antiarrhythmic medications in an attempt to decrease the frequency of these episodes; during an 8 month follow-up period, he has done well with approximately one episode of tachycardia each month requiring radio frequency atrial pacing for termination.
