Increased Heart Rate

Increased heart rate (tachycardia) is a faster-than-normal heartbeat. Drug-induced tachycardia can lead to palpitations, shortness of breath, and, in severe cases, heart complications, especially in individuals with pre-existing heart conditions.

Increased heart rate, also known as tachycardia, is a condition where the heart beats faster than normal. While a mild increase can be a normal physiological response to exercise, stress, or excitement, drug-induced tachycardia can be problematic. It may present as palpitations, shortness of breath, dizziness, chest pain, or lightheadedness. Persistent or significantly elevated heart rate can lead to complications such as arrhythmias, heart failure, or sudden cardiac arrest in vulnerable individuals. The specific symptoms and severity depend on the extent of the increase, individual health status, and any underlying heart conditions. Drug-induced tachycardia can occur due to various mechanisms including stimulation of the sympathetic nervous system, inhibition of the parasympathetic nervous system, or direct effects on cardiac tissue. Individuals with pre-existing heart conditions are at higher risk of complications from drug-induced increased heart rate.
