Single chamber pacemaker

A substantial number of studies have established the clear superiority of these pacemakers over fixed rate pacemakers as regards the clinical benefit and the exercise tolerance of patients with chronotropic incompetence. Benefits of sensor driven dual chamber pacing. Massimo Santini. In addition, the superiority of DDDR pacing versus WIR pacing due to the preservation of the a-v synchronism has been proven especially when the atrioventricular AV delay is also rate-adaptive [2—6].

Short and long terms results of dual chamber pacemaker use. J Dubernet A Fajuri. Continuous improvement of dual chamber DDD pacemakers, electrode stability and programmed sequential stimulation changed the prognosis of patients implanted with these devices. To report our experience with the use of dual chamber pacemakers.

Material and methods: One hundred seventy six patients male , aged 13 to 91 years old, who received a dual chamber pacemaker implant, are reported. Patients were followed for a mean of 2. All pacemakers were Siemens-Pacesetter and were provided with an automatic sensing and threshold device.

Post operative complications were displacement of atrial electrode in 8 patients, of ventricular electrode in 6 patients, infection in two patient and a hematoma in one. Chronic parameters, measured after six months, were within expected ranges and allowed a good reprogramming of pacemakers. Long term programming aimed to reduce battery depletion, enhance device performance and improve hemodynamic conditions.

DDD pacemakers are reliable and afford symptomatic relief in a broad spectrum of patients. A 36 years experience with implantable pacemakers. Aim To evaluate our clinical experience and results on pacemaker implantation, from to Material and methods. Computerized data collected from 2, consecutive paced patients was reviewed. A total of 3, operative procedures were performed, including procedures for complications and pacemaker replacement. Patient survival was determined from clinical records, inquiry to pacemaker manufacturers and death certificates from Servicio de Registro Civil e Identificacton de Chile Chilean Civil and Identification Registry.

Only two patients died during surgery in the study period 0. In the period, pacemakers lasted Transvenous permanent pacing can be accomplished today with a low complication rate, mainly due to better technology and surgical procedures Rev Med Chile ; To evaluate our clinical experience and results on pacemaker implantation, from to Cardiopulmonary exercise testing and its use to optimize the AV interval in dual chamber stimulation. Jun The first part of this paper describes cardiopulmonary exercise testing CPX as a non-invasive method to determine cardiopulmonary exercise capacity.

Indications, applications and technical aspects of cardiopulmonary exercise testing are discussed as well. Standard measurement values of CPX are explained together with the CO2-rebreathing technique, which allows a non-invasive measurement of cardiac output. Full-text available.

Notfalltherapie der akuten Herzinsuffizienz. Acute heart failure AHF is defined as the rapid onset of symptoms and signs secondary to abnormal heart function which may occur with or without previous cardiac disease. Diagnosis and classification of severity are primarily based on clinical findings. The conditions leading to and reasons for acute heart failure which require specific therapeutic interventions should always be taken into consideration. In the presence of ongoing signs of hypoxia, non-invasive ventilation has to be considered early.

Bradycardia in AHF patients should initially be treated with atropine; a temporal pacemaker has to be inserted if no response is achieved by medical therapy. Ventricular fibrillation and tachycardia require immediate cardioversion. Mar Z Kardiol.

Uta C Hoppe. Atrial rate-adaptive pacing may improve cardiopulmonary reserve in patients with left ventricular dysfunction. The primary endpoint was change in peak oxygen consumption VO 2. Secondary endpoints were changes in anaerobic threshold, perceived exertion, exercise duration, and peak blood pressure. Baseline VO 2 was 3. In this study, AAIR pacing did not improve peak VO 2, anaerobic threshold, rate of perceived exertion, or exercise duration compared to VVI backup pacing in patients with left ventricular dysfunction and no pacing indications.

Apr PACE. We conducted a prospective, 6-month echocardiographic study on the effect of VVI pacing on left atrial and ventricular function and dimensions in patients with sick sinus syndrome. In 26 patients who presented with and remained in sinus rhythm, paced left ventricular ejection fraction and stroke volume were significantly decreased In nine patients with atrial fibrillation at implantation paced left ventricular ejection fraction at follow-up was significantly decreased Cessation of pacing and restoration of sinus rhythm in 21 patients at follow-up did not result in any significant change of ejection fraction However, compared with preimplantation values, ejection fraction was significantly decreased In 14 of those patients, discontinuation of pacing resulted in a significant increase of left atrial fractional shortening 8.

Long-term VVI pacing in patients with sick sinus syndrome results in increase of the left ventricular end-systolic dimension and permanent reduction of the left ventricular ejection fraction.

In the left atrium, VVI pacing causes an immediate reduction of the fractional shortening as well as long-term increase of the diastolic dimension. Emergency treatment of acute heart failure. A historical analysis]. Transvenous permanent pacing can be accomplished today with a low complication rate, mainly due to better technology and surgical procedures.

User Interface — 53401 Temporary Pacemaker and Single Chamber Pacing Overview

Dual chamber versus single chamber ventricular pacemakers for sick sinus syndrome and atrioventricular block. Sick sinus syndrome SSS and atrioventricular block AV block are the two most common reasons people have pacemakers implanted. Both involve the heart beating abnormally slowly. Pacemakers replace or control the heart's own electrical activity. Single chamber pacemakers work on one of the chambers sections of the heart, while dual chamber pacemakers, which are more expensive, work on two simultaneously.

The review of trials found that dual chamber pacemakers tended to prevent more subsequent heart problems than single chamber ventricular pacemakers. The impact on people's overall quality of life is uncertain. The review did not investigate the relative benefits or risks of surgery to upgrade to a dual chamber pacemaker. Show more. Jun PACE. Rolf Nordlander.

Cardiac Electrophysiology and Arrhythmias. B Ryden Kristensson. Improvement in Myocardial Performance with Exercise. A sensor that detects body activity by low frequency sonic impulses has been incorporated in a pacemaker so that body activity may be translated to an increased pacing rate in response to exercise. The pacemaker is designed for patients who may benefit from an increased cardiac output mediated by an increased heart rate during exercise. Following permanent pacemaker implantation, six patients mean age 69 years entered a single blind, randomized, crossover trial for comparison of activity-sensing, rate-responsive pacing A to fixed rate demand pacing D.
