Pacemaker Implantation: When Is It Needed and How Does It Work?

• A pacemaker sends electrical signals to help the heart maintain a normal rate and rhythm.
• It is generally recommended for a heart rate that is too slow (bradycardia) or for certain heart block conditions.
• Implantation is usually a minimally invasive procedure performed under local anaesthesia.
• The procedure typically takes one to two hours, with most patients going home within a day or two.
• Several types of pacemakers exist, chosen based on the specific heart rhythm problem.
• Recovery generally involves some activity precautions for four to six weeks while the device settles in place.
• Regular follow-up checks monitor battery life and device function, typically every six to twelve months.
• A hospital with an experienced interventional cardiology and device implantation team supports a smoother, safer procedure and recovery.
  
  

What Is a Pacemaker and How Does It Work?

When Is a Pacemaker Needed?

• Bradycardia: a heart rate that is persistently too slow to meet the body's needs
• Heart block: a delay or blockage in the electrical signal travelling through the heart
• Sick sinus syndrome: a malfunction of the heart's natural pacemaker (the sinus node)
• Certain arrhythmias following a heart attack or heart surgery
• Fainting or dizziness caused by a slow or irregular heart rhythm
  
  

What Are the Symptoms That Might Mean You Need a Pacemaker?

• Unexplained fatigue or reduced exercise tolerance
• Dizziness or lightheadedness
• Fainting or near-fainting episodes
• A noticeably slow or irregular pulse
• Shortness of breath, particularly with exertion
  
  

Types of Pacemakers

• Single-chamber pacemaker: uses one lead, typically placed in the right ventricle
• Dual-chamber pacemaker: uses two leads, coordinating signals between the right atrium and right ventricle for a more natural rhythm
• Biventricular pacemaker (cardiac resynchronisation therapy): used for certain patients with heart failure, coordinating both lower chambers of the heart
• Leadless pacemaker: a newer, smaller device implanted directly inside the heart without separate leads, suitable for select patients
  
  

How Does Pacemaker Implantation Work?

• Local anaesthesia is used to numb the area, usually near the collarbone, and light sedation may also be given
• A small incision is made, and the lead or leads are guided through a vein into the correct position in the heart
• The pacemaker device is connected to the leads and placed in a small pocket created under the skin
• The device is tested to confirm it is sensing and pacing the heart correctly before the incision is closed
• The entire procedure typically takes about one to two hours
  
  

Is Pacemaker Implantation Major Surgery?

What to Expect: Hospital Stay and Recovery

• Most patients are monitored for a few hours to a day after the procedure
• An X-ray or device check may be done to confirm correct lead placement
• Most patients are discharged within one to two days
  
  

• Avoid raising the arm on the side of the implant above shoulder height
• Avoid heavy lifting or strenuous activity on that side while the device and leads settle into position
• Keep the incision site clean and dry, and monitor for signs of infection
• Follow any specific guidance from your cardiologist about driving and returning to work
  
  

How Long Does It Take to Recover from Pacemaker Surgery?

Living With a Pacemaker: Long-Term Follow-Up

• Regular follow-up visits, typically every six to twelve months, to check device function and battery status
• Some devices allow remote monitoring, sending data to your care team between in-person visits
• Pacemaker batteries generally last many years, and the device is replaced through a smaller procedure when needed
• Most people can resume normal daily activities, including exercise, once fully recovered
