Standard Pacemaker Implantation
Standard pacemaker implantation is a procedure to implant a device that regulates abnormal heart rhythms.
Invasive Procedure
Standard Pacemaker Implantation
The heart is a hollow muscular pump that propels blood to the different parts of the body and is controlled by electrical signals generated within the heart itself. A number of heart conditions such as bradycardia, supraventricular tachycardia, syncope, heart failure and hypertrophic cardiomyopathy can disrupt these signals and cause an abnormal heart beat, which may be too slow, fast or irregular and can lead to fatigue, shortness of breath and fainting.
A pacemaker is a small device that is implanted under the skin of the chest or abdomen to regularize an abnormal heart rhythm by transmitting regular electrical impulses to the heart muscle. Hence a pacemaker helps to relieve the symptoms due to abnormal cardiac rhythm and enables the patient to resume an active lifestyle.
The pacemaker apparatus consists of a small battery operated pulse generator and a battery. It is connected to the heart through wires and electrodes. A pacemaker battery usually lasts for about 8 to 10 years. The pulse generator recognizes an abnormal heart rhythm and responds by sending electrical pulses to correct the aberrant rhythm. Once the rhythm is normalized it stops sending signals. The pulse generator is programmed after implantation of the pacemaker, according to the individual needs of a patient.
The pacemaker can be implanted either by an endocardial (transvenous) approach or epicardial approach.

Endocardial (Transvenous) Approach
This is the most widely used approach. In this approach a small incision is made over the chest, under local anesthesia and sedation. The lead of the pacemaker is then inserted through the incision into a cardiac vein, guided by intra-operative fluoroscopy, and the lead is lodged into the heart tissue. The leads are then tested by transmitting a small amount of energy to contract the heart. After having successfully tested the leads, the other end is connected to the pacemaker. In this approach, the pacemaker is placed in a small pocket under the skin of the chest.
Epicardial Approach
This is a less common approach. It is used more often in children and patients undergoing heart surgery at the same time. This procedure is performed under general anesthesia. The lead of the pacemaker is attached to the epicardium, the outer layer of the wall of the heart. Once the leads are tested, the other end is connected to the pacemaker that is placed in a pocket created under the skin of the abdomen. This approach takes a longer operative and recovery time than the endocardial approach. This can be significantly reduced with the use of minimally invasive techniques.
Irrespective of the approach, the final adjustments of the pacemaker are made by the doctor after the pacemaker implantation by using an external device. The settings of the pacemaker depend on the individual requirement of electrical energy to stimulate normal heart rhythm.
Your cardiac surgeon will determine the best approach depending on your age and other associated conditions.

Potential Side Effects
Risks & Complications
As with any procedure, endovenous radio-frequency ablation involves minor risks and complications. They include:
- Pacemaker infection: Pacemaker infection is associated with symptoms of high temperature of 100.4F and/ or pain, swelling and redness at the site of pacemaker implantation.
- Pacemaker malfunction: Symptoms of a pacemaker malfunction may include abnormal heart beat, dizziness, hiccups or fainting.
Contact your cardiologist immediately if you experience any of the above-mentioned symptoms, after an implant surgery. Treatment of pacemaker infection mostly involves antibiotics and surgery to remove and replace the pacemaker. Pacemaker malfunction is managed by using wireless signals or magnets. If these are not effective the pacemaker has to be removed and replaced.
