Pacemaker Implantation in Indore

A pacemaker is a small, battery-powered device implanted under the skin near the collarbone to regulate the heart's electrical activity when the natural conduction system fails to maintain an adequate rhythm. Bradyarrhythmias—rhythms that are too slow, too irregular or intermittently absent can cause dizziness, blackouts and heart failure - a pacemaker resolves these by delivering precisely timed electrical impulses to keep the heart beating at an adequate rate. CARE CHL Hospitals, Indore, provides pacemaker implantation across single-chamber, dual chamber and cardiac resynchronisation therapy (CRT) configurations, supported by dedicated electrophysiology and cardiac surgery expertise.

What Is a Pacemaker?

A pacemaker consists of a pulse generator that contains the battery and electronics and is connected to one or more leads (thin wires) threaded through a vein into the heart. Common types of pacemakers are the following:

• Single-chamber pacemakers place one lead in either the right ventricle (the lower right chamber) or less commonly, the right atrium and are used for simple bradyarrhythmias such as sick sinus syndrome without AV conduction abnormality.
• Dual-chamber pacemakers place leads in both the right atrium and right ventricle, sensing and pacing each in a coordinated sequence to preserve the natural atrial-ventricular timing relationship.
• CRT (cardiac resynchronisation therapy) devices add a third lead via the coronary sinus to the left ventricle, synchronising both ventricles and improving pumping efficiency in a failing or dyssynchronous heart.

When Is a Pacemaker Needed?

A pacemaker is indicated when the heart's own electrical system cannot maintain a reliably adequate rate and rhythm:

• Sick sinus syndrome (where the sinus node fires too slowly, pauses intermittently or alternates between fast and slow rates) is among the most common pacemaker indications.
• Complete heart block (third-degree AV block) means no impulses pass from the atria to the ventricles; without pacing, the ventricular rate falls to dangerously slow escape rhythms that cannot sustain consciousness.
• Second-degree AV block may require pacing when symptoms like dizziness, syncope, or breathlessness are present or when progression to complete block is likely.
• After cardiac surgery or catheter ablation, temporary or permanent pacing is sometimes required if the procedure affects the conduction system.

Symptoms That May Indicate a Need for a Pacemaker

Several symptoms may reflect an inadequately slow or intermittent heart rhythm and warrant cardiac investigation.

• Syncope (sudden loss of consciousness) or presyncope (dizziness, lightheadedness, or near-fainting) particularly if unprovoked and recurrent, is the most important symptom and the one that most often prompts urgent investigation. Other symptoms are
• Unexplained fatigue, breathlessness or reduced exercise tolerance when the heart rate fails to rise normally with activity suggests chronotropic incompetence—the sinus node's inability to increase rate on demand.
• Palpitations that feel slow or pausing rather than fast and fluttering can indicate sinus pauses or intermittent heart block detectable on prolonged ECG monitoring.
• Worsening heart failure in a patient with left bundle branch block (LBBB) may indicate CRT rather than a standard pacemaker.

Conditions Treated with Pacemaker Implantation

Pacemaker therapy addresses specific arrhythmia diagnoses confirmed on cardiac investigation:

• Sick sinus syndrome, including persistent sinus bradycardia, sinus pauses, sinoatrial exit block and tachycardia-bradycardia syndrome.
• AV nodal conduction disease including Mobitz II and third-degree heart block 
• Carotid sinus hypersensitivity or exaggerated pausing in response to carotid artery pressure 
• Heart failure with EF below 35% and a wide QRS complex (above 150 ms) on optimal medical therapy is the indication for cardiac resynchronisation therapy with an integrated defibrillator (CRT-D).

Risks and Possible Complications

Pacemaker implantation is a low-risk procedure, though like all cardiac interventions it carries well-defined risks. They are:

• Lead displacement 
• Pocket haematoma at the device site 
• Lead infection
• Pneumothorax (collapsed lung from inadvertent puncture during subclavian venous access).

Diagnosis Before Pacemaker Implantation

A structured diagnostic pathway confirms the arrhythmia and guides device selection:

• A 12-lead ECG documents the baseline rhythm and identifies conduction abnormalities such as heart block, bundle branch block or sinus node disease at the time of investigation.
• Holter monitoring or an implantable loop recorder (a subcutaneous ECG device worn for weeks to years) captures intermittent symptoms and correlates them with ECG recordings to establish a definitive rhythm diagnosis.
• Echocardiography assesses left ventricular ejection fraction, chamber dimensions and ventricular synchrony.

Pacemaker Implantation Procedure

Most pacemaker implantations take one to two hours, performed under local anaesthesia with sedation in a cardiac catheterisation laboratory. Steps are:

• A small incision below the collarbone on the non-dominant side accesses the subclavian or cephalic vein; leads are guided under fluoroscopy (X-ray imaging) into the correct cardiac chambers.
• Lead position and electrical performance are tested at implantation to confirm adequate sensing (detecting the heart's natural activity) and pacing threshold (the output needed to reliably capture the heart muscle).
• The pulse generator is connected to the leads, placed in a subcutaneous pocket, and the incision is closed. The device is programmed to the patient's specific requirements before they leave the catheterisation laboratory.
• Patients are typically observed overnight with telemetry monitoring. A chest X-ray the following morning confirms stable lead position and device function before discharge.
