Normal heart function is not accompanied by unpleasant symptoms: heart palpitations, sinking, pain or heaviness in the chest. With tachycardia, the number of heartbeats increases significantly, the patient can literally feel the heart beating.
Tachycardia is the main cause of increased heart rate
Perfectly healthy people can feel how the heart beats after stress, heavy physical exertion, lack of oxygen in the air, intake of a large amount of caffeine-containing products, alcoholic beverages. Tachycardia is considered a physiological norm in children under 7 years of age. If in adults the heartbeat occurs systematically, this is the reason for contacting a cardiologist.
Pathological tachycardia is accompanied not only by a feeling of a strong heartbeat, but by dizziness, throbbing of the vessels of the neck, and fainting. Such symptoms can lead to the immediate development of acute heart failure, cardiac arrest, heart attack and ischemia of the heart muscle.
The heart rhythm disturbance is based on an increase in the activity of the sinus node, which is responsible for the rhythm and rate of heart contractions. An abnormal increase in the number of heartbeats leads to a decrease in blood output. The ventricles do not have time to fill with blood, which leads to a sharp decrease in blood pressure, an increase in the volume of the heart muscle
Sinus tachycardia is accompanied by an increase in the number of heartbeats from 90 to 220 beats. Most often, palpitations are the only symptom of heart failure and left ventricular dysfunction.
In addition to palpitations, there may be a lack of air, weakness, fatigue, sleep disturbances, and mood instability.
Coronary atherosclerosis leads to an increase in the number of heartbeats, angina attacks and increased symptoms of heart failure.
What to do if your heart feels like a beat
In case of tachycardia, it is necessary to undergo a medical examination: ECG, 24-hour Holter monitoring, echocardiography, magnetic resonance imaging, electrophysiological examination. A general and biochemical blood test, determination of thyroid-stimulating hormones is also recommended. To exclude all endocrine disorders that can lead to a feeling of palpitations, it is necessary to examine and consult an endocrinologist, a neurologist. With reflex and compensatory tachycardia, all the reasons that led to a significant increase in the number of heart contractions should be eliminated initially. In case of pathological tachycardia caused by heart disease, B-blockers are prescribed: "Concor", "Bisoprolol" or calcium antagonists: "Diltiazem", "Verapamil".
