Stimulants

Definition

Stimulants are drugs or medicines that increase your heart rate, breathing rate, and brain function. Some stimulants affect only a specific organ, such as the heart, lungs, brain, or nervous system.

Epinephrine is a stimulant. It is given during cardiac arrest to stimulate the heart and help restore the heartbeat.

Other times, stimulants can cause unwanted side effects. For example, pseudoephedrine found in some cold medicines can increase the heart rate.

Electrocardiogram (ECG) — An electrocardiogram is a test that measures the electrical activity of the heart. This includes the rate and regularity of beats as well as the size and position of the chambers, any damage to the heart, and effects of drugs or devices to regulate the heart.
