Slow heartbeat: is bradycardia dangerous and when is a pacemaker needed?

A slow heartbeat (bradycardia) is a resting pulse below 60 beats per minute. It may be normal during sleep or in very fit people, so you cannot draw a conclusion from the number alone. Not everyone needs a pacemaker: according to the 2021 ESC/EHRA guideline, the doctor and the patient make the decision together based on the test results. If you faint, call 103; if you feel dizzy, see a doctor.

Pacemaker: single- vs dual-chamber, implantation and recovery

A pacemaker (heart stimulator) is a small device that sends an electrical signal to the heart when it beats too slowly. According to the EHRA patient website, a single-chamber pacemaker has one lead, and a dual-chamber pacemaker has two leads. It is usually implanted under local anesthesia. You can usually return to work and everyday activities within one or two weeks. Follow your own doctor's instructions on restrictions.
