The pacemaker is a small battery-operated device that senses when the heart is beating irregularly or slowly. It sends a signal to the heart, which makes it beat at the correct rate.

Newer pacemakers weigh just 1 ounce (28 grams). Most pacemakers have 2 parts:

· The generator contains the battery and information to monitor the heartbeat.

· Leads are wires that connect the heart to the generator and carry electrical messages to the heart.

The pacemaker is implanted under the skin, it is a procedure that takes about 1 hour in most cases. The patient will be given a sedative to help relax and the patient is awake during the procedure.

In an interview for Medicine and Public Health, the clinical cardiologist and internist Jorge Mario Palmezano talks about the pacemaker procedure. The doctor explains about the electricity discharged by the pacemaker and states

“Electricity goes directly to the heart, but they are very mild electrical discharges, which are highly regulated apart from experience over time. This is a small device that comes with a titanium metal casing that does not have any type of reaction with the human body and inside this there is a battery that is based on lithium and iodine that at no time has external contact with it. body and through this battery, depending on the use, it can last for an average of 12 or 14 years ”, he concludes.

The patient after doing the pacemaker procedure can have a long operating time, if this battery runs out, the device can be changed, which is known as generated, usually there are cables connected to the heart and they go dependent on this device, after this the patient is stimulated and he will not feel anything and can lead a life without problems.

Pacemaker Procedure

A small incision is made in the region of the right or left subclavian, a pocket is created in these areas under the skin. The generator can also be placed on the abdomen, but it is less common.

Using live x-ray images to view the area, the doctor places the leads through the cut, into a vein, and then into the heart. The leads are connected to the generator and it is observed that the pacemaker is working well, depending on the technique used, you can go home or leave it under observation.

Dr. Jorge Mario explains “The patients have a clear indication since they have already gone through a cardiology medical team and have seen a cardiology specialist known as an electrophysiologist who is in charge of implanting these devices.” The devices are placed urgently or scheduled, in most cases it is scheduled, it is done on an outpatient basis or you can also go the next day after verifying that everything in the patient is correct.

Pacemaker contraindications

The pacemaker no longer presents contraindications thanks to the advances that have been made, for this reason these patients, Palmezano affirms “the patients can already use a cell phone, the refrigerator, travel by plane, play sports, go through a metal detector at an airport , enter the pool, but we always try to make sure our patients are clear that there are many benefits that the pacemaker can give them and that it improves their quality of life ”, he concludes.

Cardiovascular disease is a broad term for problems with the heart and blood vessels, these problems are often due to atherosclerosis, it is a condition that occurs when fat and cholesterol accumulate in the arteries and this accumulation is known as license plate.

The first cause in the world is cardiovascular disease and within cardiovascular diseases, acute myocardial infarction is the one that takes the first place. The doctor answers the figures of how many pacemakers are changed per day “in a day in a specialized center they can place 3 or 5 devices depending on the schedule, many times these devices are placed on patients who are admitted for emergency due to cardiovascular disease, but also for programming, which is when the patient comes with chronic discomfort, but it is quite frequent ”he explains.

Prevalence of cardiovascular diseases

The prevalence of cardiovascular diseases occurs in older adults, but nowadays it also occurs in young people who present electrical alterations and damage the cardiac electrical system or athletes who carry them, pacemakers are used for the entire population in general, not only the someone in specific if you need it. Jorge Mario “patients with pacemakers will improve their quality of life”.

Cardiovascular disease symptoms

The patient may be asymptomatic and have electrical disturbances in the heart, but he may also have severe symptoms where he has difficulty breathing, fatigue with physical activity, loss of consciousness. The doctor explains “every patient before being implanted with a device must be evaluated by a professional medical team such as a cardiologist to be able to define if this cause that has led to this electrical alteration to the heart is reversible or irreversible, if it is reversible we can treat the cause so that the patient does not need a pacemaker and if it is irreversible proceed to place the device ”he concludes.


It is important to go to an annual general check-up, in this way many diseases can be detected in time. Doctor Palmezano recommends that “from the age of 65 you start going where the cardiologist, however, it never hurts that even in healthy conditions you can go to your doctor to strengthen all the necessary measures to prevent cardiovascular disease “ends.
