What could a strong but slow pulse imply?

A strong but slow pulse can indicate several underlying conditions, often linked to changes in neurological status or central nervous system function. In the context of a skull fracture or stroke, the autonomic nervous system can be affected, leading to changes in heart rate and rhythm. This can manifest as a strong pulse that is slower than normal, which might be due to increased intracranial pressure, irritation of the vagus nerve, or significant brain injury.

The conditions involving heat exhaustion, cardiac arrest, or hyperventilation typically present with a different pulse quality. For example, heat exhaustion might lead to a rapid heart rate as the body tries to cool down, and cardiac arrest typically has no pulse. Hyperventilation is associated with a rapid pulse due to the body's fight-or-flight response. Therefore, the presentation of a strong but slow pulse is more closely aligned with neurological events, making skull fracture or stroke the correct implication in this scenario.
