Are you waking up with a fast heart rate? Don’t be subjective to this. Find out why and how to fix this situation in the article below!

What is a fast heart rate?

According to Livestrong, tachycardia is defined as a heart rate greater than 100 beats per minute. A rapid heartbeat does not mean that the blood rushes out of the heart more than usual. But it causes the contractions of the heart chambers to occur too short, causing blood to stagnate in the heart, leading to excessive blood feeding. little. This long-term process can lead to dangerous complications such as thrombosis, stroke, heart failure, even cardiac arrest.

Why are you waking up with a fast heart rate?


Wake up from a deep sleep with a pounding heart can be a sign of anxiety or a neurological disorder (cardiac nerve disorder). If you are facing a lot of stress in your life, with signs of appetite, insomnia, you may be able to explain the cause of tachycardia when you first wake up. However, this situation may also be because you have just woken up from a nightmare.


Some common causes of increased heart rate, whether you are awake or sleeping, are caffeine, energy drinks, alcohol and certain drugs, such as inhaled asthma drugs and flu drug, cardiovascular medicine… All these substances are considered stimulants to increase your heart rate.

waking up with a fast heart rate
Fast heart rate if only due to the normal physiological response of the body is usually not dangerous. However, if the heart palpitations are frequent or appear in the background of another cardiovascular disease, it may be a dangerous arrhythmia that needs treatment.


We often don’t pay attention to our sleep schedule and only go to sleep when actually feeling sleepy. But less practical sleep causes unexpected effects on our cardiovascular system.

Less sleep has been shown to cause adverse effects on the heart. Many studies have shown an association between low sleep and high blood pressure.

Recently, a small study published in the journal Hypertension indicates that naps are associated with some negative signs, especially when these naps are not in the nighttime normal.

Less sleep not only causes fatigue but also a potential risk of heart disease.

The secret to reducing tachycardia

Drink a lot of water

60-70% of the human body is water, so water is very important for health. Water is the solvent for active substances. Not having enough water will probably lead to mild palpitations, due to electrolyte imbalance. Therefore, adding enough water every day will help maintain a stable heart rate.


When the heart rate increases rapidly and becomes a disease, the phenomenon of palpitations can occur at any time, even while sleeping, making the person more prone to startling and nervousness. Therefore, when you see your heart beating so fast, relaxing and exercising regularly will help reduce many of the symptoms of anxiety.

Electrolyte balance

The contraction of the heart is due to the electrocardiographic impulse generated by the difference in charge of four important ions in the cell, including K +, Ca2 +, Na +, Mg2 +. For some reason, the charge of these ions is altered which can lead to cardiac arrhythmias. Therefore, the best way to limit tachycardia is to ensure that these concentrations of ions are balanced and stable.

Wanting to stabilize these concentrations of ions needs to know which foods they contain. Potassium is found in fruits such as apples, bananas, oranges, milk, and bread. Calcium is found in almonds, oatmeal, milk, and tofu. Sodium is abundant in meats, dairy products or pieces of bread. And food sources rich in magnesium come from nuts or grains …


Drugs are indispensable in controlling tachycardia. You are required to use medications prescribed by your doctor if you have a rapid heart rate to relieve symptoms, slow the progression of the disease, and prevent complications such as stroke, thrombosis … However, it should not be placing too much faith in treatment drugs, because some cases can cause side effects that aggravate the heart rhythm disorder.

These are explanations for your fast heartbeat when you sleep and after you  start waking up with fast heart rate. It is best to monitor your heart rate regularly, minimizing the causes that may increase your heart rate and monitor accompanying symptoms. If heart palpitations are occurring more and more with signs of palpitations, palpitations, fatigue, lightheadedness … then you should go to the cardiologist as soon as possible to have an accurate diagnosis and appropriate treatment.
