With the installation of a pacemaker, the heart rate can be maintained at a normal level of 60 to 100 beats per minute.
The normal value of heart rate is 60~100 beats per minute, while the elderly people are on the slower side, they can be lower than 60 beats per minute, but not lower than 40 beats per minute.
The pacemaker is mainly for bradycardia and bradyarrhythmia, these people’s heart rate is lower than 60 beats per minute, there will be insufficient blood supply to the heart, such as chest tightness, chest pain, palpitations, dizziness, etc. Through the implantation of the pacemaker to play the role of replacing the heart beat, so that the heart does not fall below the normal heart rate, to maintain the perfusion of the whole body, to prevent the tissue ischemia and lack of oxygen to appear symptoms.
Therefore, after implantation, the heart rate can reach normal, but the specific settings can be set according to the needs of the number of times, for example, set 50 beats per minute, and the heart rate can reach or exceed 100 beats per minute during exercise and excitement, which is a normal phenomenon.
