Pacemakers

“The human heart works continuously to pump oxygen and nutrients throughout the body. Its rhythm is controlled by a natural electrical system that keeps the heartbeat steady and coordinated. When this electrical system does not work properly, the heart may beat too slowly, or irregularly. This can affect blood flow to the body and may cause symptoms such as fatigue, dizziness, fainting, or other serious heart complications. For such conditions, a cardiologist may recommend pacemaker surgery, a safe and effective way to restore a healthy heartbeat. Modern devices used in pacemaker treatment are small, advanced devices that monitor and regulate the heart’s rhythm with precision. If you are considering a pacemaker operation in Dubai or Abu Dhabi, The Heart.ae offers advanced cardiac care, expert diagnosis, and personal care from pacemaker implantation through recovery and follow-up.”

What Is a Pacemaker?

A pacemaker is a small medical device that is implanted under the skin in the chest to help regulate a person’s heartbeat. It is used to treat conditions such as bradycardia, which is an abnormally slow heartbeat where the electrical impulses that control the heart’s rhythm are blocked or delayed. A pacemaker surgery can help restore a normal heart rate, which can improve symptoms such as fatigue, dizziness, and shortness of breath. Pacemakers are commonly used in older adults who have heart conditions that affect the electrical system of the heart. However, they can really be implanted at any age even in infants.

How Pacemaker Treatment Helps Regulate Heart Rhythm

The pacemaker is programmed to monitor the heartbeat and deliver electrical impulses as needed to keep the heart beating at a normal rate. It can be adjusted by a doctor to ensure that it is providing the appropriate level of support for the patient’s needs.

The pacemaker works by sending electrical signals to the heart to stimulate contractions and maintain a regular heartbeat. It is made up of a small electronic chip, a battery, and wires with electrodes that are connected to the heart (pacemaker leads). These components are typically implanted during pacemaker surgery.

The first practical pacemakers were developed in the mid-20th century. Over the years, pacemaker technology has continued to evolve, with improvements in battery life, programming, and size. Today, pacemakers are much smaller and more reliable than early models, and are used to treat a wide range of heart conditions. This advancement has greatly enhanced the effectiveness of pacemaker treatment.

Types of Pacemakers Used for Treatment

There are several types of pacemakers available, each designed to meet the specific needs of patients with different types of heart conditions. Some of the most common types of pacemakers include:

Single-chamber pacemakers

These pacemakers have one lead that is placed in either the right atrium or the right ventricle of the heart. They are typically used to treat bradycardia (slow heart rate)

Biventricular pacemakers

Also known as cardiac resynchronization therapy (CRT) pacemakers, these devices have three leads that are placed in the right atrium, right ventricle, and left ventricle of the heart. They are used to treat heart failure in patients with a weakened heart muscle.

Dual-chamber pacemakers

These pacemakers have two leads, one placed in the right atrium and the other in the right ventricle. They are used to treat heart block, where there is a delay or complete blockage in the electrical impulses that regulate the heartbeat.

Leadless pacemakers

These pacemakers are much smaller than traditional pacemakers and do not require leads to be implanted into the heart. Instead, they are inserted directly into the heart through a vein in the leg.


Who Needs Pacemaker Surgery Treatment?

Not everyone with a heart condition needs a pacemaker. A cardiologist will recommend Pacemaker Surgery if diagnostic tests, such as an ECG or a Holter monitor, show that the heart’s electrical pathways are not working properly. People with the following rhythm disorders or electrical conduction problems may benefit greatly from pacemaker treatment.

When the resting heart rate is too slow, usually less than 50-60 beats per minute. It becomes problematic when blood is not supplied fast enough to the body.

Heart block happens when electrical signals traveling through the heart are delayed or blocked. This can disrupt normal heart rhythm and cause serious symptoms. A pacemaker operation in Dubai or Abu Dhabi helps restore proper communication between the heart’s chambers.

This condition affects the heart’s natural pacemaker, known as the sinus node. If it becomes damaged or wears down with age, it can cause the heart to alternate between dangerously slow and fast rhythms. It can also cause the heart to pause for several seconds. Patients with severe symptoms benefit from pacemaker surgery.

Some patients with atrial fibrillation may experience dangerously slow heart rates due to medications or underlying conduction problems. A pacemaker treatment is recommended to stabilize the heartbeat.

Specialized pacemakers, such as cardiac resynchronization therapy (CRT) devices, help improve coordination between the heart’s chambers in patients with heart failure.

Some patients develop conduction defects after heart surgery and need temporary or permanent pacemaker treatment.

Pacemaker Operation : Procedure and Recovery

The procedure to implant a pacemaker typically takes 1-2 hours and is performed under local anaesthesia, with the patient awake but sedated. Here are the general steps involved:

The patient is prepared for the procedure by having an IV line inserted and being connected to monitors to track their heart rate, blood pressure, and oxygen levels. The skin is sterilised and the patient is covered with sterile drapes.

A small incision is made in the chest near the collarbone, and the electrophysiologist creates a pocket under the skin for the pacemaker device.

One or more leads are inserted through a vein in the chest and guided to the heart. The leads are then attached to the pacemaker device and tested to make sure they are working properly.

The pacemaker device and leads are then inserted into the pocket created earlier under the skin. The device is then tested to ensure that it is functioning properly and delivering the correct electrical impulses.

The incision is closed using sutures or surgical staples.

The electrophysiologist will use a special programmer to communicate with the pacemaker and program the parameters depending on the case.

After the procedure, the patient is taken to a recovery room and monitored for a few hours. They will need to avoid strenuous activity and heavy lifting for several weeks while the incision heals.

The patient will need to have regular check-ups with their doctor to ensure that the pacemaker is functioning properly and to make any necessary adjustments to the device’s programming.

Overall, pacemakers are an important tool in the management of heart disease and can help improve the health and quality of life of individuals with certain heart conditions through pacemaker treatment.

Benefits of Pacemaker Treatment

Modern pacemaker surgery offers several important benefits apart from correcting a slow heartbeat to patients suffering from rhythm disorders.

The primary purpose of a pacemaker is to maintain a healthy and stable heartbeat, ensuring proper blood circulation throughout the body.

Many patients experience significant relief from symptoms like dizziness, fatigue, fainting episodes, breathlessness, and weakness.

After recovery, most patients can resume work, travel, exercise, and engage in social activities comfortably. They experience better sleep quality and emotional well-being after a pacemaker operation in Dubai or Abu Dhabi.

Untreated abnormal heart rhythms can increase the risk of falls due to fainting, heart failure, and cardiac arrest due to reduced oxygen supply to organs. A Pacemaker treatment helps lower these risks.

A pacemaker operation in Dubai or Abu Dhabi is usually performed under local anesthesia with mild sedation. Patients need hospitalization for just one or two days.

Today’s pacemakers are smaller, more accurate, and longer-lasting. New ones are MRI-compatible, and wireless monitoring is possible. They are leadless, hence reducing complications associated with traditional wires.

Risks and Complications of Pacemaker Surgery

Although pacemaker surgery is generally safe, like any medical procedure, it carries some risks. Fortunately, serious complications are uncommon when performed by experienced specialists such as Dr Moutaz El kadri at The Heart.ae. Main risks are:

An infection may develop near the implantation site. Symptoms can include redness, swelling, and pain near the site. Some may experience a mild fever.

Mild bruising around the incision area is common and usually resolves without intervention. This complication is common in patients taking blood thinners.

In rare cases, the pacemaker leads may shift from their original position. A brief follow-up procedure is performed to adjust the wire.

This uncommon complication can occur if the lung is accidentally punctured during lead placement. It is easily treatable by the medical team.

Some patients may experience a reaction to anesthesia or materials used in the device during pacemaker treatment.

Although rare, pacemakers may occasionally experience technical issues that require adjustment or replacement.

There is a very low risk of blood clot formation in the veins near the pacemaker leads, which may cause swelling or, rarely, more serious complications.

Some strong electromagnetic fields, such as those from MRI machines or industrial equipment, can interfere with older pacemaker models. But nowadays modern MRI-compatible devices are used in pacemaker operations in Dubai or Abu Dhabi.

 To minimize complications: 

  • Choose an experienced heart rhythm doctor and dedicated cardiac center 
  • Follow all post-surgery instructions 
  • Attend regular follow-up appointments 
  • Avoid strenuous arm movement immediately after surgery 

At The Heart.ae, we ensure successful outcomes during every pacemaker surgery.

Pacemaker Battery Replacement

Pacemakers run on batteries that last between 5 and 15 years, depending on the device type, usage frequency, pacemaker settings, and the patient’s condition.
  • Return of original symptoms such as dizziness or fatigue
  • A slower-than-programmed pacing rate noted during follow-up
  • Device alerts communicated through your remote monitoring system
  • Approaching the manufacturer’s estimated battery end-of-life date

Modern pacemakers alert physicians before the battery becomes critically low. At The Heart.ae, we maintain a proactive follow-up program that ensures no patient reaches a critical battery level without timely intervention. Our team coordinates every aspect of the replacement process, from pre-operative testing to post-procedure device programming.

Pacemaker battery replacement is usually simpler than pacemaker surgery.
The procedure generally involves:

  • Opening the existing incision site
  • Disconnecting the old pulse generator
  • Connecting the new generator
  • Testing the device
  • Closing the incision
