A pacemaker is a small medical device used to help manage certain abnormal heart rhythms, particularly when the heart beats too slowly or the electrical signals controlling the heartbeat do not function normally.
The heart has its own electrical system that coordinates each heartbeat. When this system develops a problem, the heart may not pump blood effectively enough to meet the body's needs. Some people experience dizziness, weakness, fainting, unusual fatigue or breathlessness, while others may have rhythm abnormalities detected during medical testing.
A pacemaker may be considered in conditions such as:
- Symptomatic slow heart rate
- Certain forms of heart block
- Electrical conduction problems
- Specific rhythm disorders requiring pacing support
Pacemakers do not treat every type of heart disease or irregular heartbeat. The decision depends on symptoms, ECG findings, heart rhythm monitoring and the underlying electrical problem.
The device generally consists of a pulse generator and leads that help deliver electrical impulses when necessary. Modern devices can monitor heart rhythm continuously and respond according to programmed settings.
For patients in Pune and other parts of Maharashtra, cardiac evaluation before pacemaker treatment may involve an ECG, ambulatory rhythm monitoring, echocardiography or other investigations depending on the clinical situation.
At The Heart Clinic, Dr. Satyajeet can assess symptoms and rhythm findings to determine whether further electrophysiological evaluation or pacing therapy is appropriate.
People experiencing unexplained fainting, recurring dizziness or unusually slow pulse rates should have the cause properly evaluated. Identifying the underlying rhythm disturbance is the first step toward deciding whether a pacemaker or another treatment approach is suitable.
