Abstract:
Data on the development of left ventricular dysfunction after permanent pacemaker implantation are available. According to data from the DAVID (The Dual Chamber and VVI Implantable Defibrillator) study, it was shown that DDDR-paced patients had significantly more fatal events and HF deterioration cases requiring hospitalization. Similar were the results of the MOde Selection Trial (MOST), which poses serious questions to the cardiology community. For that reason it is important to understand how PPM implantation changes the hemodynamic parameters of the heart and what consequences this may have. On the one hand, asynchronous contraction of the paced heart and increase in AF risk with advancing age require active screening of asymptomatic paroxysms of tachyarrhythmias to promptly adjust therapy. On the other hand, minimizing the rate of ventricular pacing through proper programming of the devices should not be overlooked. Recently, various biomarkers have been validated to select high-risk patients in which the therapeutic strategy can be modulated on time.
