Detailed explanation-1: -Answer: The position of a pacemaker can shift over time. After about a year, however, a strong capsule has formed around the device and it should not move any further. Because the device and the leads are very secure at this point, you can exercise without restrictions.
Detailed explanation-2: -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.
Detailed explanation-3: -The most common reason people get a pacemaker is their heart beats too slowly (called bradycardia), or it pauses, causing fainting spells or other symptoms. In some cases, the pacemaker may also be used to prevent or treat a heartbeat that is too fast (tachycardia) or irregular.
