HEART PALPITATIONS

HEART PALPITATIONS


Cardiac causes of sinus tachycardia

Cardiac causes of sinus tachycardia


The main way to regulate the heart rate is an electrical impulse, which is sent by the sinus node in the heart. This impulse spreads to all muscle fibers of the heart and forces them to contract simultaneously: in this way, the main function of the organ is realized – to push portions of blood through the main vessels. Violations in the sinus node are caused by the effects of various substances (hormones, chemical compounds).
With sinus tachycardia, the number of heartbeats usually ranges from 90 to 120 beats per minute, in some cases it reaches 150 to 160. Sinus tachycardia sometimes appears during eating, physical activity or emotional stress. It occurs with various diseases and is accompanied by symptoms characteristic of them.
So, palpitations are common in myocarditis (inflammation of the heart muscle) of various origins. At the same time, along with rapid heartbeats, there appear:
feelings of interruptions in the work of the heart,arrhythmia of heart contractions,shortness of breath ,chest painweakness and fatigue , joint pain (not always), a slight increase in body temperature .
Also, sinus tachycardia often occurs with heart failure , which may be a consequence of coronary artery disease or heart defects. In such cases, heart palpitations are also combined with shortness of breath, weakness and increased fatigue, which are often accompanied by edema of the lower extremities. If such symptoms appear, you should consult a cardiologist as soon as possible . After the underlying disease is eliminated, tachycardia will also disappear.
In addition, a rapid heartbeat is one of the symptoms of anemia. With anemia, due to a lack of hemoglobin, oxygen delivery to the tissues decreases. As a compensatory response, the sinus node begins to generate more electrical impulses, the heart contracts more often, and blood circulates faster to bring the lacking oxygen to the tissues. Tachycardia with anemia is accompanied by a number of additional symptoms:
shortness of breathweakness and dizziness”Flies” before the eyes,pallor (sometimes cyanosis) of the skin,chillinesshair loss and brittle nails,pinching on the tip of the tongue,numbness of the limbs.
In the presence of tachycardia and most additional symptoms, you should first consult a physician . After donating blood to determine the level of hemoglobin and serum iron, the doctor will determine for sure whether there is anemia. If anemia occurs, you may need to consult other specialists to establish the true cause of the disease.
Arterial hypotension is a condition in which sinus tachycardia occurs. It is often preceded by severe emotional stress, disturbances in sleep and wakefulness, and inadequate nutrition. In addition to heart palpitations, hypotension is characterized by drowsiness, irritability, apathy, memory impairment, headache, nausea, and dizziness. In this case, you should pay attention to your lifestyle: normalize nutrition, daily routine and physical activity.
An increase in heart rate is associated with intoxication. Abuse of drinks containing caffeine (coffee, tea, energy drinks), as well as certain medications, leads to sinus tachycardia.


Causes of paroxysmal tachycardia


In addition to sinus tachycardia, paroxysmal tachycardia is distinguished. It differs in that the impulse that causes contractions of the heart does not come from the sinus node, but from other, pathological pacemakers. With this type of tachycardia, the heart rate reaches 180 – 240 beats per minute. This condition can occur against the background of various heart lesions, so it is best to contact a cardiologist. The symptoms of paroxysmal tachycardia are very specific:
a sharp heartbeatdyspnea,weakness,a feeling of tightness in the chestpallor of the skin,pulsation of the cervical veins.


Respiratory failure as a cause of tachycardia


A decrease in the function of the respiratory system affects the functioning of the heart. The mechanism of tachycardia is approximately the same as in anemia, because in case of deterioration of the lungs, there is a lack of oxygen. There are many diseases that lead to respiratory failure, and they all have their own symptoms. The most common signs, along with a rapid heartbeat, are:
difficulty inhaling or exhalinga feeling of suffocationthe need to strain additional muscles during breathing (abdominal muscles, shoulder girdle),sleep and memory disturbances,headaches ,cough.
If palpitations are accompanied by such symptoms, you should definitely contact a pulmonologist , and if this is not possible, then a therapist.


Tachycardia with endocrine disorders

Why should tachycardia be treated?


Some disorders in the work of the endocrine system directly affect the work of the heart. Sinus tachycardia occurs under the influence of excessive amounts of thyroid hormones in thyrotoxicosis. In addition to heart palpitations, this disease is characterized by
a feeling of heatincreased body temperatureexcitability and frequent mood swings,sleeplessness ,weight loss with increased appetite,violation of the menstrual cycle in women, a change in facial [removed]it takes on an angry look).
Much less common are adrenal tumors that intensively synthesize adrenaline. Rapid heartbeat is observed with pheochromacytoma. In addition to tachycardia, this disease manifests itself as a sharp increase in blood pressure, fear, anxiety, chills, headaches, pain in the heart, nausea, sweating and a feeling of thirst. Often these symptoms occur simultaneously, so the condition can be described as an attack. If, along with tachycardia, these signs occur, you should consult an endocrinologist .


Why should tachycardia be treated?


Rapid heartbeat is a rather dangerous symptom that must be eliminated as soon as possible. Due to the frequent contractions, the heart does not get enough rest and is quickly depleted. As a result, heart failure occurs – a mismatch between the body’s needs for oxygen and the work of the heart.
Therefore, if tachycardia appears, you should consult a doctor. Even in the absence of specific symptoms that would accompany a rapid heartbeat, it is enough to start seeing a therapist. After completing the necessary examinations, he will refer you to the appropriate specialist.
