There are certain risks associated with pacemaker installation, such as vascular puncture, perforation of the heart muscle, and risk of poor healing of the capsule, but the probability of the risks occurring is relatively low. A pacemaker is a pulse generator consisting of a battery and circuitry that sends tiny regular electrical pulses to the heart to stimulate it to beat when needed. Pacemakers are suitable for people with severe sinus bradycardia, patients with sick sinus node syndrome, patients with weak heart contractions, and cardiac arrest patients. Pacemaker implantation is a relatively safe and routine procedure, with the following main categories of risks: 1. Risk of vascular puncture: the implantation process of pacemaker may lead to pneumothorax, bleeding, etc; 2. Risk of myocardial perforation: because cardiac electrodes need to be fixed in the endocardium, if the operation is too rough or if the patient’s myocardium has a variant, the electrodes may penetrate into the endocardium, leading to cardiac perforation; 3. Risk of poor healing of the capsule: if the patient is diabetic or has a very weakened body and poor healing function, the incision may not be able to heal after the operation, and there is even a risk of blood accumulation, fluid accumulation, infection and ulceration in the capsule; 4. Other risks: In the long term, some patients may experience relatively rare complications such as poor pacing function, lead breakage, battery failure, and pacemaker malfunction. Pacemaker implantation is a safer and more effective form of treatment, with clear benefits compared to the risks of surgery. Once a pacemaker is installed, it can be very helpful in improving the patient’s heart muscle function and quality of life. It is important to go to a regular hospital for diagnosis and treatment, as well as regular follow-up visits and pacemaker battery renewal. Due to individual differences, details should be consulted with a specialist after consultation.
