Heart rhythm is a cyclic change in the electrical activity of the heart that occurs as a result of contraction and relaxation of the heart muscle. These changes are an important indicator of heart health and can help identify various heart diseases and disorders.
One of the most common types of heart rhythm is sinus rhythm, which is a normal and healthy condition of the heart. However, there are also other types of heart rhythm, such as atrial fibrillation, ventricular tachycardia, atrial fibrillation and others.
Heart rhythm can change depending on various factors such as age, gender, physical activity, stress level, etc. Changes in heart rhythm can be caused by various diseases, such as coronary heart disease, hypertension, heart failure, arrhythmia, etc.
In medicine, heart rhythm is studied using electrocardiography (ECG). An ECG is a method for studying the electrical activity of the heart by recording electrical potentials arising on the surface of the body. An ECG allows you to evaluate the heart rate (HR), the presence of arrhythmia and other heart rhythm disturbances.
When studying heart rhythm, it is important to consider not only the heart rate, but also the shape of the heart rhythm. The shape of the heart rhythm can be sinus, atrial fibrillation, paroxysmal, etc. Each of these types of rhythm has its own characteristics and may indicate various heart diseases.
Thus, heart rhythm is an important indicator of heart health that can help identify various disorders and diseases. The study of heart rhythm is carried out using an ECG and allows you to evaluate the shape and frequency of heart contractions.
