Drinking tea in moderation does not usually lead to tachycardia, but if it is strong or consumed in excess, it may induce tachycardia. Tachycardia refers to a heart rate of more than 100 beats per minute. Some organic heart diseases, such as coronary heart disease, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, myocarditis, etc.; as well as chronic obstructive pulmonary disease, hyperthyroidism, severe anemia, electrolyte abnormalities and other diseases may cause tachycardia. Daily strenuous exercise, drastic changes in mood, drinking alcohol, drinking strong tea or coffee can also cause physiological tachycardia, usually after a period of time can be recovered on their own. Drinking a moderate amount of tea will not cause tachycardia, but only drinking strong tea or a large amount of tea may lead to sympathetic excitation, which will accelerate the heart rate. Therefore, it is recommended to drink light tea in moderation to avoid adverse symptoms.
