This study is tracking people who experienced sudden atrial fibrillation (an irregular heartbeat) during an acute illness or hospitalization. You would receive a small insertable cardiac monitor — a device about the size of a small flash drive — that your doctor implants under your skin to continuously record your heart's rhythm. The researchers want to understand how often the irregular heartbeat comes back after the initial episode and whether it happens more frequently in people who had surgery versus those who got sick from other causes.
When people develop an irregular heartbeat suddenly during an illness or hospital stay, doctors don't always know whether it will come back. This study exists to track heart rhythms over the long term so doctors can better understand patterns and eventually help predict who needs treatment after these episodes.

You would have a small heart monitor device implanted under your skin during a brief procedure — this is part of your standard care, not an experimental treatment. After implantation, the device continuously monitors and records your heart rhythm. You would attend follow-up visits so doctors can check the device and review your heart rhythm data over time. The study will track you to see if your irregular heartbeat returns and how often it happens.
