Remote monitoring (RM) is the newest function of cardiac implantable electronic devices (CIEDs). In our observational retrospective analysis, we aimed to assess whether telecardiology could be a safe alternative to routine outpatient examinations during the COVID-19 pandemic. The in- and outpatient visits, the number of acute cardiac decompensation episodes, the RM data from CIEDs, and general condition were examined via questionnaires (KCCQ, EQ-5D-5L). Regarding the enrolled 85 patients, the number of personal patient appearances was significantly lower in the year following the pandemic outbreak compared to the previous year (1.4 ± 1.4 and 1.9 ± 1.2,p= 0.0077). The number of acute decompensation events was five before and seven during lockdown (p= 0.6). Based on the RM data, there was no significant difference in heart failure (HF) markers (all relatedp> 0.05); only patient activity increased after restrictions were lifted compared to that before the lockdown (p= 0.03). During restrictions, patients reported increased anxiety and depression compared to their previous state (p< 0.001). There was no subjective change in the perception of HF symptoms (p= 0.7). Based on the subjective perception and CIED data, the quality of life of patients with CIED did not deteriorate during the pandemic, but their anxiety and depression intensified. Telecardiology may be a safe alternative to routine inpatient examination.
