**2. Patient selection**

Patients are nominated for pacemaker (PPM) and implantable cardiac defibrillator (ICD) implantation according to the patient's history, symptoms and signs, physical examinations and other documents, cardiac imaging (echocardiography) in case of bradycardia/tachycardia, and based on the 2021 European Society of Cardiology (ESC) guidelines on cardiac pacing and cardiac resynchronization therapy, which was developed by the Task Force on cardiac pacing and cardiac resynchronization therapy [1].

A majority of all pacemaker implantations are indicated to patients above 60 years old. After admitting the patient and obtaining informed consent, the necessary blood tests, chest X-ray, and electrocardiography are taken, and then the patient is prepared for the procedure. The patient is transferred to the electrophysiology laboratory, where it is essential to have properly functioning equipment. In addition, standard air conditioning is crucial in controlling air infections. In the era of the Covid-19 pandemic, we need to consider health protocols and guidelines for the personal protection of staff and patients. If there is no emergency condition, pacemaker and ICD implantation should be delayed; otherwise, we must follow all the instructions and protocols related to the prevention of the disease.
