First seen Nov 01, 2025 · Last updated Jun 12, 2026 · Updated 27 times

Summary

This study is for people starting a type of cancer drug called BTK inhibitors, which can sometimes cause irregular heartbeats. Researchers will implant a small heart monitor under the skin to continuously check for problems like atrial fibrillation. The goal is to learn how often these heart issues happen and how doctors respond, so they can better manage risks in the future. About 50 adults with blood cancers like CLL will take part.
