BACKGROUND The hemodynamic advantages of maintaining AV synchrony through AV synchronous pacing are widely known as compared to single chamber pacing. DDD pacemaker implantation entails higher cost and is technically more challenging than the VDD pacemaker. METHODS Seventy one patients underwent VDD lead (Biotronik GmbH, St. Jude Medical and Medtronic Inc.) implantation at KEM hospital, Mumba...

background: permanent pacemakers provide effective relief of symptoms and are life-saving in patients with symptomatic heart block. implantable cardioverter defibrillators (icd) are also increasingly recognized as life-saving tools in various groups of patients with malignant ventricular tachyarrhythmias. methods: as part of the “world survey on pacemaker and icd implantations”, a survey of all...

A 57-year-old womanwith a history of dizziness due to episodes of complete heart block and bradycardia was referred to the electrophysiology ward for pacemaker implantation. A dual chamber pacemaker (Medtronic, Relia, Medtronic, Minneapolis, USA) was implanted. Its analysis showed normal function (atrial lead capture threshold 0.5 V at 0.4 ms, ventricular lead capture threshold 0.75 V at 0.4 ms...

In surgeries that require the implantation of a pacemaker, the endocardial pacemaker leads are introduced into the cardiac chambers through subclavian or axillary venous catheterization or cephalic vein cutdown. The drawback of this type of surgery is scarring of the pectoral area, which can be a serious cosmetic problem especially for young women. In this study, we report on 2 cases where a pe...

A 75-years-old female presented with dyspnea and syncope. Electrocardiogram revealed atrial fibrillation and complete atrioventricular block. She was therefore listed for pacemaker implantation on the next day. Initial attempt at venous access was left axillary vein. A venogram showed good venous anatomy (Fig. 1a). Several attempts to puncture axillary vein were made. However, there was no good...

INTRODUCTION The pacemaker implantation VDD is considered simpler, faster, less expensive and causes fewer complications compared to DDD. However, the VDD pacemaker has not been widely used in many centers, perhaps for fear of dysfunction of the sinus node and the reduction of atrial sensitivity by the pacemaker during follow-up after implantation. OBJECTIVE To compare patients with DDD and V...

After the introduction of the implantable cardioverter defibrillator (ICD) in clinical practice by Mirowski in 1980 [Mirowski et al., 1980] the first available devices offered only a basic ventricular pacing option. Since approximately 5-20% of patients with an indication for ICD therapy following implantation criteria at that time (secondary prevention) needed antibradycardia pacing as well, t...

BACKGROUND Pacemaker generators are routinely implanted in the anterior chest. However, where to place the generator may need to be considered from the mental, functional, and cosmetic standpoints. METHODS In this study, we performed the left axillary pacemaker generator implantation with a direct puncture of the left axillary vein in 40 consecutive patients, and evaluated the late safety and...

A 76-year-old patient with a medical history of hypertension, type 2 diabetes mellitus and moderate valvular aortic stenosis underwent cephalic DDD pacemaker implantation because of fatigue and a 3rd degree atrioventricular block with a ventricular escape rhythm of 45 beats per minute. After implantation, he complained about stabbing chest pains. A chest radiograph did not reveal any signs of a...

BACKGROUND The additional purpose for pacemaker implantation, beyond treating arrhythmias and conduction disturbances, is to improve the quality of life (QoL) of the patient. Most previous research has shown this purpose to have been achieved. However, the question as to whether all mental and physical components improve QoL to the same degree is still valid. The purpose of this study is to eva...
