Learn About Sick Sinus Syndrome
Sick sinus syndrome (also known as sinus node dysfunction) is a group of related heart conditions that can affect how the heart beats. "Sick sinus" refers to the sino-atrial (SA) node, which is an area of specialized cells in the heart that functions as a natural pacemaker. The SA node generates electrical impulses that start each heartbeat. These signals travel from the SA node to the rest of the heart, signaling the heart (cardiac) muscle to contract and pump blood. In people with sick sinus syndrome, the SA node does not function normally. In some cases, it does not produce the right signals to trigger a regular heartbeat. In others, abnormalities disrupt the electrical impulses and prevent them from reaching the rest of the heart.
Sick sinus syndrome can result from genetic or environmental factors. In many cases, the cause of the condition is unknown.
Sick sinus syndrome accounts for 1 in 600 patients with heart disease who are over age 65. The incidence of this condition increases with age.
Most cases of sick sinus syndrome are not inherited. They are described as sporadic, which means they occur in people with no history of the disorder in their family.

Summary: The purpose of the BIO-CONDUCT study is to demonstrate the safety and effectiveness of the BIOTRONIK Solia CSP S pacing lead when implanted in the left bundle branch area (LBBA). Safety will be assessed by evaluating serious adverse device effects that occur through 3 months post-implant. Efficacy will be assessed by evaluating implant success rate.
Summary: A multicenter, prospective, randomized study in a 1:1 ratio, single-blind with double-blind evaluation to evaluate the superiority of physiological ventricular pacing (proposed modality) vs. managed ventricular pacing (control) for prevention of persistent AF (PeAF) occurrence in patients with prolonged atrioventricular interval (PR≥180 ms) and indication for pacing: sinus node disease and/or paro...
