The Russian doctor, Daria Sergeyevna, a cardiologist, revealed the causes of the “palpitations” of the heart.
In an interview with the newspaper “Izvestia”, the specialist notes that palpitations mean that the heart rate is higher than 100 beats per minute. The causes of this condition are many, some of which are related to the health of the heart, and some to the presence of a disorder in other parts of the body.
The specialist adds that the most common cause is sinus tachycardia, which usually occurs during exercise, strenuous work, stress and during pregnancy. It also occurs in children, adolescents, and people with low blood pressure.
Sinus tachycardia may be a symptom of a disease such as hypothyroidism and a manifestation of anemia, even after drinking alcohol and smoking.
“Atrial fibrillation is the most dangerous form of tachycardia, where the heart rate may reach 200 per minute and more, and this condition is accompanied by a feeling of shortness of breath, general weakness and dizziness. However, some patients do not notice their rapid and irregular pulse,” she says.
And she adds, this disease becomes more dangerous in the absence of timely medical care, as it may lead to stroke or heart failure.
The specialist indicates that the other type of palpitations is paroxysmal tachycardia, that is, a paroxysmal increase in heart rate from 150 to 200 beats per minute or more. When a seizure of this type begins suddenly, the person feels general weakness, shortness of breath, blurred vision, and may lose consciousness. Young people often develop this type of arrhythmia, as it is associated with the presence of additional pathways in the heart, from birth, and over time they can “wake up” and cause tachycardia.
She says, “The most dangerous type of palpitations is ventricular tachycardia (ventricular fibrillation), which is generated in one of the ventricles, although it is not adapted to this work, and the heart cannot contract effectively, which leads to a dangerously low blood flow rate. The person loses consciousness, breathing stops, the pulse is not detected and clinical death develops. Therefore, immediate resuscitation measures are required.”
And she adds, this condition is usually affected by people who suffer from heart problems, including those who have had myocardial infarction, cardiomyopathy, and so on.
The specialist notes, however, that there are a number of congenital heart diseases, which cause life-threatening ventricular tachycardia and which leads to sudden cardiac death with no other symptoms. Such as arrhythmias due to right ventricular dysplasia, long QT syndrome, short QT syndrome, Brugada syndrome, polymorphic ventricular tachycardia, and others.
