Bazetta Indicator

The Bazett index is a mathematical index that is used to estimate the heart rate (HR) of a person. It was developed by American cardiologist William Bazett in the 1920s and named after him.

The Bazetta index is calculated using the formula:

B = 60 / (R - 0.6)

where B is the Bazetta index, R is the time interval between two consecutive heartbeats.

Interpretation of the bazetta index allows you to estimate a person’s heart rate at rest and during physical activity. The higher the bazetta index value, the higher the heart rate.

The use of the bazetta indicator has practical applications in medicine, for example, to determine the risk of developing cardiovascular diseases in patients with hypertension. This index can also be used in sports to assess the physical fitness of an athlete.

Despite the fact that the basal indicator was proposed more than 100 years ago, it still remains one of the most common indices used to assess heart rate and determine the state of the human cardiovascular system.

Stephen B. Rether proposed to use as a new criterion for the recovery time of coronary circulation the ratio of the product of the number of pauses greater than 0.2 seconds after the ECG before and during movement and the proportion of total movement time in the form of a two-factor indicator, which he designated as the “Bazetta indicator”.

Work by S.B. Reter, as well as some other researchers (V.V. Volotovshchikova, E.A. Osipova, E.N. Melentyev, A.I. Chukanova, V.P. Loginov), nevertheless remained outside the scope of attention of cardiologists and practitioners , although it was she who largely contributed to improving the work of the clinical arrhythmology department of the Scientific Center for Cardiovascular Surgery named after. A.N.Bakuleva RAMS.

The use of the baset-B indicator characterizes the compliance of the heart rhythm with the target heart rate frequency, determined by both basal metabolism and the physical activity of the patient. The method is widely applicable in patients complaining of palpitations and unsatisfactory quality of life. Normalization of the adjusted time of blood flow restoration according to the Basalla criterion reduces the symptoms of tachycardia and improves the quality of life of patients. At the same time, there are some aspects of the manifestation of autonomic dysfunction and coronary insufficiency that need to be discussed in this publication in order to further clarify the feasibility of this important new indicator.
