====== Heart Monitor ======

Human [[:guards:]] have **Heart Monitors**, which raise the [[:alarm tracker]] by 2 steps when they are killed.

Additionally, in [[:modes:Expert Plus]] mode or otherwise when playing with the "alarm when KO" [[:modes:custom]] difficulty setting enabled, a guard's Heart Monitor also raises the [[:alarm tracker]] by 1 step when he is [[:KO|knocked out]], unless he is already knocked out.

Heart Monitors can be permanently disabled using [[:items:EMP Packs]] or [[:agents:Dr. Xu]]'s [[:augments:Subdermal Tools]]. Heart Monitors are also bypassed by [[:weapons:#ranged weapons]] using the [[:augments:Anatomy Analysis]] augment. When a guard's Heart Monitor is disabled or bypassed, killing him or knocking him out does not raise the alarm tracker.

All human guards have a Heart Monitor, except for [[:guards:OMNI Harbingers]] who instead have a [[:guards:OMNI Harbinger#Consciousness Monitor]] and an [[:guards:OMNI Harbinger#Improved Heart Monitor]]. Note that when hovering over an OMNI Harbinger in the user interface, the tooltip //additionally// shows that he has a standard Heart Monitor, but this is misleading; an OMNI Harbinger's Heart Monitor never has any effect, so practically speaking OMNI Harbingers do not have Heart Monitors.
