Cardioarterial Interval

Cardioarterial interval

The cardioarterial interval (also known as the cardio-arterial interval) is the time interval between the heartbeat and the subsequent peripheral pulse. It reflects the time of propagation of the pulse wave from the heart to the peripheral arteries.

The cardioarterial interval depends on arterial stiffness and vascular compliance. The higher the stiffness of the arteries and the lower their distensibility, the shorter the cardio-arterial interval.

An increase in the cardio-arterial interval can be observed with atherosclerosis, hypertension, diabetes mellitus and other diseases accompanied by a decrease in the elasticity of the arteries.

The cardioarterial interval is an important diagnostic indicator that allows one to assess the stiffness of the arterial wall. Its measurement is used in clinical practice to identify disorders of the cardiovascular system and monitor the effectiveness of treatment.

Cardioarterial intervals are the time intervals separating the periods of heartbeat and blood pressure. Intervals are important for studying the relationship between heart function and the state of blood flow in the arteries. In this article we will look at what aspects of the cardioarterial interval and how it is related to cardiovascular diseases, as well as ways to treat and prevent them.

Determination of cardiointerval

Cardiac interval is the time interval from the beginning of contraction of one chamber of the heart to the beginning of contraction of the next. It is measured by an electrocardiograph (ECG). Depending on its duration at each specific moment of the cardiac cycle, the following are distinguished:
