Complications and Recovery from Bundle Branch Block
Complications and recovery from bundle branch block vary based on the type of block and any underlying cardiac disease. While many people live without issues, complications of bundle branch block can include heart failure, arrhythmias, and difficulties diagnosing heart attacks.
One of the primary concerns with left bundle branch block is that it may indicate or worsen underlying heart disease. It often occurs in people with weakened heart muscle and may lead to or exacerbate:
- Heart failure due to poor synchronisation of ventricular contractions
- Worsening of existing cardiomyopathy
- Increased risk of sudden cardiac arrest in some high-risk groups
In right bundle branch block, complications are less common but may be significant if related to congenital defects or pulmonary conditions.
Another complication is difficulty diagnosing myocardial infarction (heart attack). LBBB can mask typical ECG signs of a heart attack, making it harder for doctors to recognise and treat acute events quickly. Special criteria, such as Sgarbossa’s, are used to assist with interpretation.
People with recurrent fainting, fatigue, or reduced exercise tolerance may require pacemaker implantation, especially if the block leads to complete heart block or dangerously slow heart rhythms.
Complications and Recovery from Bundle Branch Block
Recovery depends on the cause and severity. If the bundle branch block is isolated and no underlying disease is found, the outlook is generally excellent, with little to no lifestyle limitation.
In patients who require pacemakers or cardiac resynchronisation therapy, recovery includes device programming, follow-up monitoring, and sometimes rehabilitation for heart failure.
Lifestyle strategies such as managing blood pressure, maintaining a healthy weight, avoiding tobacco, and treating sleep apnoea can all improve heart function and reduce complications.
With proper care and monitoring,recovery from bundle branch block are manageable, and many people lead healthy, active lives with or without medical intervention.
