Complete heart block is a serious heart rhythm disorder in which electrical signals from the upper chambers of the heart do not reach the lower chambers normally. This can make the heart beat too slowly and reduce blood flow to the body.
At Sparsh Hospital, patients can access specialist cardiac evaluation and treatment for heart rhythm disorders. Prompt medical assessment is important because untreated complete heart block can lead to fainting, heart failure or cardiac arrest.
Complete heart block, also called third-degree atrioventricular (AV) block, occurs when electrical impulses from the atria cannot pass normally to the ventricles. The ventricles then rely on a slower backup rhythm, which may not provide adequate blood flow.
Severity and cause determine immediate management. People with complete heart block require urgent medical assessment, even when symptoms are mild or absent.
Symptoms can develop suddenly or gradually and are usually related to a slow heart rate and reduced blood flow. They may include:
Some people may have few symptoms despite having significant conduction disease. Sudden fainting, severe breathlessness, chest pain or loss of consciousness requires emergency medical attention.
Complete heart block can result from conditions that damage or interfere with the heart’s electrical conduction system. Causes may include:
The cause is important because some reversible factors, such as certain medicines or acute medical conditions, may need to be addressed alongside rhythm management.
An electrocardiogram (ECG) is the main test used to identify complete heart block. It can show that the atria and ventricles are beating independently and help doctors assess the heart rate and rhythm.
Doctors may also recommend continuous ECG or Holter monitoring, echocardiography, blood tests and other cardiac investigations to identify the underlying cause and assess heart structure and function. The tests selected depend on the patient’s symptoms, medical history and clinical condition.
Complete heart block treatment depends on whether the condition is reversible, how stable the patient is and whether the conduction abnormality persists.
Unstable patients may need immediate treatment to support heart rate and circulation. Temporary pacing may be used as a bridge to more definitive treatment.
A permanent pacemaker is the main long-term treatment for persistent complete heart block that is not caused by a reversible or physiological condition. The device delivers electrical impulses to help maintain an appropriate heart rate.
If medicines are contributing to the heart block, doctors may review or change them when appropriate. Conditions such as a heart attack or other underlying cardiac problems also require specific treatment.
The pacing approach is selected based on the patient’s rhythm, heart function, anatomy, and clinical needs.
After pacemaker implantation, patients require follow-up to check the device and monitor heart function. The treating team may guide wound care, activity, medicines and device checks. Patients should report new dizziness, fainting, breathlessness or other concerning symptoms.
Anyone diagnosed with a complete heart block should receive specialist cardiac evaluation. Symptoms such as fainting, severe dizziness, chest discomfort, breathlessness or an unusually slow pulse require urgent assessment.
A cardiologist in Bangalore, particularly one experienced in heart rhythm disorders, can evaluate ECG findings, identify possible causes, and determine whether temporary or permanent pacing is required.
A Complete Heart Block treatment hospital should provide rapid rhythm assessment, specialist cardiology care, and access to cardiac device implantation when required.
Sparsh Hospital provides cardiac rhythm management supported by cardiologists, electrophysiologists and advanced cardiac infrastructure. Its services include ECG, echocardiography, Holter monitoring, electrophysiology studies and pacemaker, ICD and CRT implantation, along with emergency cardiac care.
Patients searching for a Complete Heart Block treatment centre in Bangalore can consider Sparsh Hospital for specialist cardiac evaluation and rhythm management. Cardiac services are available across locations including Infantry Road, Hennur, Yeshwanthpur, Yelahanka, RR Nagar and Sarjapur Road. Patients should confirm service availability at their preferred location.
Complete heart block is a serious electrical conduction disorder that can cause a dangerously slow and unreliable heart rhythm. Because persistent third-degree AV blocks can carry significant risks, prompt specialist assessment is important. Treatment may involve emergency stabilisation, temporary pacing, treatment of a reversible cause and, in many persistent cases, permanent pacemaker implantation.
At Sparsh Hospital, patients can access specialised cardiac rhythm care, advanced diagnostics, pacemaker implantation and long-term follow-up under a multidisciplinary cardiac team.
Yes. Complete heart block can cause a very slow heart rate, fainting, heart failure or cardiac arrest. It requires urgent medical assessment.
A persistent complete heart block that is not caused by a reversible condition generally requires permanent pacing. The cardiologist determines the appropriate device and timing.
Some medicines can slow electrical conduction and contribute to heart block. Doctors review medicines and decide whether adjustment is appropriate.
An ECG is the primary test used to diagnose complete heart block. Additional monitoring and imaging may help identify the cause.
