Tachycardia is a significant symptom associated with cocaine overdose due to the drug's stimulant effects on the central nervous system. Cocaine increases the release of neurotransmitters like norepinephrine, which stimulate the heart and can lead to an elevated heart rate. This response is part of the body's fight-or-flight mechanism, as the use of cocaine often results in heightened alertness, energy levels, and an increased metabolic state.

In the context of cocaine overdose, tachycardia may progress further and can be accompanied by other cardiovascular issues, such as hypertension and arrhythmias. Monitoring and managing heart rate are critical in treating patients experiencing an overdose, as these cardiovascular symptoms pose serious risks to health.
