Tachycardia is the primary cause of increased heart rate
To feel his heart beating, can completely healthy people after stress, heavy physical exertion, lack of oxygen in the air, drinking large amounts of caffeinated products, alcoholic beverages. Tachycardia is considered physiologically normal in children up to 7 years. If the adult heartbeat occurs systematically, that is the reason for going to a cardiologist.
Pathological tachycardia is accompanied not only by a feeling of palpitations, but dizziness, throbbing of vessels of neck, faint. These symptoms may lead to the immediate development of acute heart failure, cardiac arrest, heart attack and ischemia of the heart muscle.
The basis of heart rhythm disorders is the increase in the activity of the sinus node responsible for the rhythm and pace of cardiac contractions. A pathological increase in heart rate leads to a decrease in ejection of blood. The ventricles do not have time to fill with blood, which leads to a sharp decrease in blood pressure, increase heart muscle
Sinus tachycardia is accompanied by an increase in heart rate from 90 to 220 beats. Most often, the heart feeling is the only symptom of heart failure and left ventricular dysfunction of the heart.
In addition to the heartbeat can be felt shortness of breath, weakness, fatigue, sleep disturbances, mood instability.
Coronary atherosclerosis leads to increased heart rate, angina attacks and increasing symptoms of heart failure.
What if feels like beats the heart
With tachycardia should undergo a medical examination: ECG, daily monitoring by Holter, echocardiography, magnetic resonance imaging, electrophysiological study. Also recommended General and biochemical analysis of blood, definition of thyroid-stimulating hormones. To the exclusion of all endocrine disorders that can lead to palpitations, it is necessary examination and consultation with an endocrinologist and a neurologist. In a reflex compensatory tachycardia initially you should eliminate all the causes that have led to a significant increase in the number of cardiac contractions. In pathological tachycardia caused by heart disease, prescribed-blockers: "Concor", "Bisoprolol" or calcium antagonists: Diltiazem", "Verapamil".
Advice 2: Why fast beating heart
Some people know the condition when the heart suddenly starts speeding up for no apparent reason. Rapid heartbeat may be conditioned by several factors, which, in turn, caused by diseases of the cardiovascular system or other external influences.
Tachycardia is a heart rate more than 100 beats per minute. It may occur as a result of increased activity of the region which is above the ventricle – this is called supraventricular tachycardia. There are five types of supraventricular tachycardia: atrial flutter, atrial tachycardia, atrial fibrillation, syndrome Wolff-Parkinson-white and atrioventricular nodal reciprocal tachycardia.
Supraventricular tachycardia often occurs in people with perfectly healthy hearts who do not even notice heart palpitations.
Atrial flutter is typically called age-related heart disease and is characterized by internal discomfort, frequent heartbeat, shortness of breath, fatigue and a feeling of tightness in the chest. However, the most common cause of palpitations is atrial fibrillation, which develops for no apparent reason. Its symptoms begin to appear with age and represent the intermittent pulse, dizziness, shortness of breath and irregular heartbeat frequent. If the heart beats too fast, people can lose consciousness.
Problems with the heart ventricles
Heart rate exceeding 120 beats per minute, is called ventricular flutter. This condition is dangerous to their excessively rapid contraction in which the ventricles do not have time to fill with blood and the heart pumps into the vascular system a very small amount of blood rich in vital oxygen. Most often, ventricular flutter occurs in patients with heart disease who suffered a heart attack or suffer from narrowing of the coronary arteries.
Flutter heart ventricles traditionally treated such procedures as defibrillation, is performed in a hospital.
If the heart beats with a frequency of 300 beats per minute or more, the diagnosis "ventricular fibrillation". The steady conservation of this state, the patient loses consciousness from collapse of the cardiovascular system and is experiencing oxygen deprivation. In the untimely appeal in an ambulance a result of ventricular fibrillation may occur irreversible damage to the brain and other internal organs, and death.
To control the palpitations, you need to identify and cure the disease that provokes its repetition. In certain severe cases, doctors prescribe the patient the implantation of cardioverter-defibrillator.
