What is the best treatment for left bundle branch block?
What is the best treatment for left bundle branch block?
People with heart failure and left bundle branch block may need cardiac resynchronization therapy or CRT. This is a type of pacemaker therapy that helps the ventricles contract at the same time. CRT can increase the amount of blood that the heart ejects and can improve symptoms of shortness of breath and fatigue.
Can you call STEMI with LBBB?
As with all LBBB, there is a small r-wave in V1-V3 and a deep S-wave. Can you diagnose STEMI here? —Yes! The diagnosis of STEMI in the presence of left bundle branch block has been problematic for years.
Can you fix a left bundle branch block?
Unfortunately LBBB is not reversible. In your case, in the absence of any structural heart disease and symptoms, the overall risk of cardiovascular morbidity or mortality should be very low.
Why is LBBB a STEMI mimic?
This is further complicated because an LBBB itself is a risk factor for cardiac death and any new LBBB can be the presenting ECG pattern in a proximal left anterior descending coronary artery (LAD) occlusion. Thus, a new LBBB ECG pattern in patients with a compatible clinical scenario is considered a STEMI equivalent.
What are the treatment options for LBBB?
LBBB itself has no specific treatment. The condition is usually permanent and requires treatment of underlying disorders. The exception to this is in HFrEF with sinus rhythm, and LBBB with QRS duration greater than 150 ms with NYHA class II-IV heart failure will benefit from cardiac resynchronization therapy as recommended by the ACC and AHA.
What is the prevalence of LBBB with mi?
About 1 in 200 patients with MI have LBBB. Sgarbossa’s is a well accepted approach at determining which LBBB are having an MI. In the original Sgarbossa criteria, a score of <3 typically is not considered diagnostic of acute MI, but also does not rule out MI.
Can LBBB be seen in patients without any clinical disease?
Although LBBB is often associated with significant heart disease and is often the result of myocardial injury, strain or hypertrophy, it can also be seen in patients without any particular clinical disease. This activity reviews the cause and presentation of LBBB and highlights the role of the interprofessional team in its management. Objectives:
When is immediate reperfusion indicated in patients with suspected mi and LBBB?
Clinically or hemodynamically unstable patients with suspected MI and new LBBB should be considered for immediate reperfusion therapy per guidelines.
