Summary
Left bundle pacing (LBP) is a viable alternative for patients experiencing His-bundle pacing failure. This technique offers a solution for His-bundle pacing non-responders, improving outcomes in cardiac pacing.
Area of Science:
- Cardiology
- Electrophysiology
- Medical Devices
Background:
- His-bundle pacing is a novel technique for cardiac pacing, aiming to reduce pacing-induced side effects.
- Despite its advantages, His-bundle pacing does not achieve a 100% success rate, necessitating alternative strategies.
Purpose of the Study:
- To evaluate the efficacy of left bundle pacing or peri-left bundle pacing (LBP/peri-LBP) in patients who failed His-bundle pacing.
- To assess left ventricular contraction and desynchrony following LBP/peri-LBP implantation.
Main Methods:
- The study involved patients with atrioventricular block who previously failed His-bundle pacing.
- LBP/peri-LBP techniques were employed to directly capture the left bundle or adjacent ventricular tissue.
- Post-procedure assessments included evaluation of pacing success rates, left ventricular contraction, and desynchrony.
Main Results:
- LBP/peri-LBP demonstrated success in patients with failed His-bundle pacing.
- The study assessed the impact of LBP/peri-LBP on left ventricular function and synchrony.
Conclusions:
- Left bundle pacing or peri-left bundle pacing serves as an effective alternative ventricular pacing method.
- This approach is particularly beneficial for patients with atrioventricular block who are not candidates for or have failed His-bundle pacing.

In skeletal muscles, acetylcholine is released by nerve terminals at the motor endplate—the point of synaptic communication between motor neurons and muscle fibers. The binding of acetylcholine to its receptors on the sarcolemma allows entry of sodium ions into the cell and triggers an action potential in the muscle cell. Thus, electrical signals from the brain are transmitted to the muscle. Subsequently, the enzyme acetylcholinesterase breaks down acetylcholine to prevent excessive...

Smooth muscle contraction is a complex process vital for various bodily functions, from maintaining blood vessel tension to facilitating the movement of food through the digestive tract. Unlike striated muscles, smooth muscle contraction begins more slowly and lasts longer.
The onset of contraction is triggered by an increase in calcium ions within the sarcoplasm, similar to the process in striated muscle. However, smooth muscles have a relatively smaller reservoir of the sarcoplasmic...

5.6K
Skeletal muscle fibers have the unique ability to switch between rest and contraction states, using different sources of ATP for energy. The contraction cycle and Ca2+ transport back into the sarcoplasmic reticulum for relaxation require significant ATP. However, the ATP reserves in muscle fibers are limited and can only sustain contractions for a few seconds. Additional ATP production becomes necessary for prolonged contractions. As a result, muscle fibers generate ATP through various sources,...
