Lithium
Lithium Primary batteries are used in pacemakers since they meet the requirements of long life, low drain current and voltage characteristics. The shelf life of primary lithium cells is typically equivalent to a 10% loss of capacity over five years.

The SA node is sometimes called the heart’s “natural pacemaker.” The SA node sends electrical impulses at a certain rate, but your heart rate may still change depending on physical demands, stress, or hormonal factors.

The Cleveland Clinic cardiologist who led the study concluded that physicians should switch off the pacemaker function on dual-chamber implantable defibrillators because it may knock the heart out of rhythm and hasten heart failure. The pacemaker uses a mild electrical impulse to continuously control the heartbeat.

Pacemakers: dos and don’ts

Don’t use an induction hob if it is less than 60cm (2 feet) from your pacemaker. Don’t put anything with a magnet within 15cm (6in) of your pacemaker. Don’t linger for too long in shop doorways with anti-theft systems, although walking through them is fine.

Baseline patient characteristics are summarized in Table 1: The median patient survival after pacemaker implantation was 101.9 months (approx. 8.5 years), at 5, 10, 15 and 20 years after implantation 65.6%, 44.8%, 30.8% and 21.4%, respectively, of patients were still alive.
