Heart Monitor is an unsplicable non-solid block which was added in the Growtopia General Hospital update, alongside the addition of Surgical Kit. This item can only be obtained from purchasing said pack.
Just as the description says, the red light of a Heart Monitor will constantly blink when the placer of the item is online. A message saying "[Username] Status: Online/Offline" will also appear.
- Heart Monitor's function to detect whether the placer is online or not is a reference to actual heart monitors, which are generally used to detect whether a hospital patient is still alive or not.
- Due to several reasons, most likely technical limitations, only up to 32 Heart Monitors can be placed in a world. A message about "wiring concerns" would appear when a player tries placing the 33rd.
- It takes a while for Heart Monitors to update.
