Even a healthy person can feel an increased heartbeat. It is often felt by people with increased nervous sensitivity. The following factors can lead to an increased heart rate:
- quick rise to height;
- significant physical effort;
- physical activity in a stuffy and hot environment (a lack of oxygen leads to an increased heart rate);
- severe mental stress, such as agitation or fear;
- medications such as medicines for the common cold
- the use of products containing caffeine (coca-cola, tea, coffee);
- disturbances in the digestive system, when the diaphragm rises slightly.
Do not hurry!
Had a dream about how you fainted? Give up a recent idea, for you will suffer a sad defeat. The period has come when you need to rest, think, choose new goals, but not act.
If you manage to lose consciousness in a dream, then in real life a very calm period begins. There will be so few events that you will literally scream with longing and boredom.
It is bad to see how others fall into unconsciousness. According to the dream book, this means that you will shock people with unreasonable behavior.
Possible reasons
Heart rhythm disturbances can signal cardiac pathologies. In such cases, you should immediately consult a doctor and undergo the necessary examination. In addition to cardiac pathologies, the syndrome can occur for the following reasons:
- disturbances in the work of the endocrine system;
- psychogenic diseases;
- intoxication from toxic substances;
- closed injuries;
- cardiosclerosis;
- hypoxia;
- vegetative-vascular dystonia;
- myocardial dystrophy;
- heart defects;
- low hemoglobin.
Any of the following can trigger heart palpitations at night while sleeping. To determine the main factor, you need to undergo a comprehensive examination. Now we need to consider the causes most often causing the syndrome of nocturnal heartbeat.
High blood pressure
An increase in blood pressure during a night’s sleep may well provoke an increase in heart rate. Hypertension, which manifests itself precisely at night, can be either a separate pathology or be the result of an incorrect selection of drugs for the treatment of hypertension.
In such cases, it is usually necessary to adjust the dose of medications so that the effect is prolonged (long-lasting) and the effect of taking them lasts even at night. Since high blood pressure during sleep is the most common cause of heart palpitations, it is important to know what to do during your next nighttime attack:
- drink cool water – when it enters the esophagus, it normalizes the heart rate;
- take a comfortable position, preferably half-sitting, to reduce blood flow to the veins of the heart;
- wash your face with cool water;
- Take a medication prescribed by your doctor to lower your blood pressure;
- provide a free flow of fresh air into the room.
It is important not to panic, to calm down, while breathing deeply and evenly.
Low pressure
Nocturnal tachycardia in hypotonic patients is quite common. The very low blood pressure in this case does not provoke an increase in heart rate. This happens when a concomitant pathology joins the hypotension, for example:
- vegetative dystonia;
- Iron-deficiency anemia;
- increased anxiety;
- pain syndrome from an injury received the day before.
In the presence of such pathologies in a hypotonic person, nocturnal awakenings from attacks of tachycardia are not uncommon. Heart palpitations with low blood pressure are accompanied by:
- nausea, up to vomiting;
- dizziness and pain in the temples;
- pallor and cyanosis of the skin;
- feeling of fear, panic;
- soreness in the sternum.
If the symptoms are pronounced, it is recommended to call the ambulance team, and before her arrival, drink water, you can take a sedative, for example, an infusion of valerian.
Tachycardia during pregnancy
While carrying a child, a woman’s body undergoes significant changes in organs and systems.
Heartbeat at night in a dream worries many pregnant women, and in most cases it does not signal any serious pathology.
It is necessary to take measures and consult a doctor for examination when the following symptoms join the nocturnal tachycardia:
- pain in the temples and behind the sternum;
- fainting;
- dizziness, nausea.
To avoid a nightly increase in heart rate, expectant mothers are recommended to have adequate rest, proper nutrition, avoidance of nervous overload and stress.
Panic attacks
This is the name for attacks of strong, causeless anxiety, which occur more often at night. The state of panic attack is accompanied by the following symptoms:
- sudden awakening from a strong heartbeat;
- excessive sweating;
- lack of air;
- numbness of the limbs.
With the development of such a condition, the patient may not realize that he has a psychological problem and for a long time does not go to the doctor, regularly experiencing attacks of nocturnal heartbeat and panic. To eliminate these manifestations, the help of a psychologist is required, to eliminate the root cause of nocturnal tachycardia – depressive disorders and neuroses.
Decreased vagus nerve tone
The autonomic nervous system has a complex system of regulation, and the vagus nerve is the main component of this process. At night, under its influence, the heartbeat slows down, the level of blood pressure decreases, the body rests. With a decrease in the tone of the vagus nerve, the activity of the sympathetic part of the nervous system increases, this leads to an increase in pressure and the development of tachycardia during nighttime sleep. With this problem, you need to contact a neurologist for diagnosis and therapeutic measures.
As you can see, there are not so few reasons provoking an increase in the heartbeat at night. In addition to the above, it can be alcohol abuse, chronic fatigue, insomnia, family troubles. What kind of pathology causes tachycardia syndrome should be determined by the doctor, based on the general clinical picture and concomitant diseases of the patient.
Required examinations
If you suspect epilepsy, as well as in any case of loss of consciousness during sleep, it is imperative to undergo an examination.
The doctor will send the patient to an encephalographic study to find out what is the activity of different areas of the brain. It is often carried out using functional tests. In most patients with subcortical epilepsy, changes are found that are expressed as a slow wave-peak combination.
Cortical epilepsy gives a different picture: erratic peaks, slow waves and bursts follow each other rather chaotically.
In addition, the patient must undergo an examination of the functional capabilities of the heart muscle. An echocardiogram is performed, during which the size, volume, filling, and functioning of large vessels are assessed. Sometimes it is also necessary to undergo daily ECG monitoring ( Holter ). The need for this study is due to the fact that the doctor needs to exclude pathologies of the heart rhythm, which can also give a picture similar to fainting, especially at night.
