Abstract

Elektrostimulator srca dio je elektrostimulacijskog sistema koji generiranjem impulsa nadomješta oslabljenu kronotropnu funkciju. Elektrostimulacijski sistem čine generator impulsa i elektrode koje se uvode u miokard. Generiranjem impulsa val se depolarizacije širi i uzrokuje kontrakciju miokarda čime se osigurava normalan ritam otkucaja. Indikacije za ugradnju trajnog elektrostimulatora srca u posljednjih su se 20 godina uvelike proširile i time utjecale na broj implantiranih uređaja i kvalitetu života srčanih bolesnika. U centru za implantaciju elektrostimulatora srca KBC-a Sestre milosrdnice u 2013. godini implantirano je 242 uređaja. Najčešća indikacija su atriventrikularni blokovi provođenja, slijedi fibrilacija atrija s bradiaritmijom ventrikula, pa bolest sinoatrijskog čvora, sindrom hipersenzitivnog sinusa karotikusa i infranodalne smetnje provođenja. Ovisno o poremećaju električnog sistema srca ugrađuju se različiti tipovi elektrostimulatora. U KBC Sestre milosrdnice najčešće se implantirao DDD elektrostimulator, dvokomorni uređaj koji ima dvije elektrode, jednu u desnoj pretkljetki, drugu u desnoj klijetki, što omogućava „fiziološku“ sekvencijsku stimulaciju srca.

Abstract (english)

Pacemaker is a part of heart's electrical system. It replaces impaired chronotropic function by generating impulses. Heart's electrical system is consisted of pulse generator and electrodes which are attached to the surface of the myocardium. By generating a pulse, wave of depolarization spreads and causes contraction of the myocardium ensuring the normal rhythm of the heart. Indications for permanent pacemaker implantation in the past 20 years have greatly expanded and thus affected the number of implanted devices and the quality of life in cardiac patients. At the center of implantable pacemakers of The University Hospital Sisters of Charity in 2013., 242 devices were implanted. The most common indications are atrioventricular block, atrial fibrillation with ventricular bradyarrhythmias, sinus node dysfunction, carotid sinus hypersensitivity and infranodal conduction block. Depending on the disorder of the heart's electrical system, various types of pacemakers are installed. The most common pacemaker implanted at The University Hospital Sisters of Mercy is DDD pacemaker, dual-chambered device that has two electrodes, one in the right atrium, another in the right ventricle, and it allows "physiological" sequential stimulation of the heart.
