Understand the differences between palpitation, tachycardia and arrhythmia

You are at rest and suddenly your heart starts to beat faster for no apparent reason, sometimes accompanied by shortness of breath and chest pain. These are some of the symptoms related to palpitation, tachycardia and arrhythmia.

Cardiovascular diseases are the leading cause of death in the world. The heart is an essential organ for humans, as it pumps blood throughout the body. So it is important to take good care of him.

In the content below, we discuss the main differences between palpitation, tachycardia and arrhythmia, their causes and possible treatments. Keep reading to learn more!

What is the difference between palpitation, tachycardia and arrhythmia?

Palpitation occurs when you consciously feel your heartbeat irregularly. It is the famous feeling that “the heart will come out of the mouth”.

This condition, in general, is associated with stress , tiredness after physical effort, shortness of breath and chest pain. It may be related to tachycardia but does not necessarily indicate heart disease.

Arrhythmia is a type of cardiac disorder that can make the heart beat too fast or too slowly. This condition is called tachycardia when the heart rate is above 100 beats per minute and bradycardia when it is below 60 beats per minute.

What are the causes and symptoms of each disease?

As already mentioned, the main symptom of palpitation is the conscious awareness of the heartbeat. It can have several causes ranging from strong emotions like anxiety, fear and pain, to dehydration of the body.

Arrhythmias, including tachycardia, may have more severe symptoms such as chest pain or discomfort, shortness of breath, dizziness, fainting, paleness and palpitations.

They happen due to a mismatch in the cardiac electrical system that can be caused by both heart diseases such as hypertension and coronary artery disease as well as by the use of drugs, hyperthyroidism and excessive caffeine consumption.

What is the appropriate treatment for these diseases?

The evaluation of these diseases must be done by a cardiologist. He will be able to identify the cause of the condition in question and thus indicate an effective treatment.

For example, a patient who is experiencing palpitations due to anxiety disorders will have a different treatment than the one with dehydration of the body.

In the case of arrhythmias and tachycardia, there may be a need for surgery (when the person suffers a heart attack, for example) or the use of equipment attached to the heart. In other patients, the use of medications may be sufficient to control this condition.

Now that you know the differences between palpitation, tachycardia and arrhythmia it is important to be aware of its signs. See a cardiologist when you feel that there is something abnormal with your heart, as he is the professional prepared to treat these diseases.

Remember that your health is very important. So keep your exams up to date and visit a good medical clinic at least once a year for a checkup.
