Tachycardia: here are 7 causes that make your heart beat too fast

Heart rhythm disorder, tachycardia is characterized by the acceleration of heartbeats. Besides physical exercise, here are the factors that can cause palpitations.

Tachycardia results in an abnormal acceleration of the heart rate, and can have several causes. Generally, we speak of tachycardia when the heart exceeds 100 beats per minute.

The pregnancy

Palpitations are sometimes felt during pregnancy. This phenomenon is particularly linked to the increase in blood volume. The heart of the pregnant woman is thus more solicited, and tends to get carried away.

Energy drinks

Overconsumption of coffee, tea, and other energy drinks fortified with caffeine or taurine can also increase blood pressure and cause abnormal heartbeats.

The alcohol

Same for alcoholic beverages. Excessive alcohol consumption can lead to a rapid heart rate. Knowing that palpitations can also occur during withdrawal in alcohol-dependent people.

The tobacco

Another possible cause: smoking, and more specifically the nicotine contained in tobacco. Tachycardia is one of the signs of nicotine overdose. This is also the case for cocaine, heroin, and other exciting drugs.


When the pulse is greater than 100 beats per minute at rest, this may on the other hand be linked to hyperthyroidism, a disorder of the thyroid gland which results from an abnormally high production of thyroid hormones.

Taking certain medications

Palpitations are sometimes felt after taking certain medications. This particularly concerns certain decongestant treatments used to treat rhinitis, or even salbutamol, to fight against asthma.

anxiety disorders

It can be associated with emotional disturbances, such as anxiety and stress. During a period of tension, the adrenal glands secrete several substances, including cortisol, which increase the heart rate.
