Heart Palpitations During Pregnancy

doppler-ultrasound-381363_1920Pregnancy brings a lot of changes to the body. Except stomach growth, there are a lot of transitions which don’t meet the eye, such as heart palpitation. This is a sensation where one can feel like as if the heart wants to jump out of the chest. This kind of feel can radiate towards the throat and it may seem like the heart is in your neck. It can be very frightening, especially since you’re not afraid only for your sake but for the baby as well. There are some other causes that can result in increased heart rate such as coffee, nicotine and alcohol, but in pregnancy, there are many different reasons.

Increased Volume Of The Blood

As you may know, when a woman gets pregnant, the volume of the blood increases up to 50% or more due to a baby’s circulation. This is to ensure that the baby gets all the nutrients and oxygen that it requires. So, when that increased volume of blood starts to flow through the same heart, it has to work harder in order to succeed in sending all the blood to every part of the body. There are two components which influence on the heart work, which is frequency and cardiac output. The heart is starting to pump at a higher frequency in order to achieve in sending all the blood to the system. At that level of frequency, there are more “mistakes” and sometimes heartbeats can seem a bit asynchronous. These are the things that a pregnant woman senses as a palpitation. It lasts for a few seconds and subsides on its own.


Progesterone is the females hormone which has the role in making changes in pregnant women. High concentration of progesterone can have an impact on cardiovascular system leading to tachycardia. It makes a heart rate faster and makes the heart work stronger, which also leads to heartbeat “mistakes” mentioned above as palpitations. This also ensures that the fetus gets enough blood for a proper development.


A pregnant woman has many things on her mind, but also is more emotional due to hormonal change. It is important to segregate from the stressful situations and to be surrounded by positive and calm people. It is recommended for a pregnant woman to include some relaxing ritual like meditation or yoga, deep breathing and massage for mind escaping.
