Protodiastole (Protodiastole)

Protodiastole is a short period during the cardiac cycle that begins after the end of systole but before the closure of the aortic valve. At this moment, the heart is at rest and is preparing for the next cycle.

Protodiastole is an important stage of the cardiac cycle, as it determines the beginning of the diastolic phase. During protodiastole, the heart relaxes and fills with blood, allowing it to prepare for the next systole.

The duration of protodiastole can vary depending on various factors such as age, gender, physical activity, etc. In healthy people, protodiastole usually lasts about 0.1 seconds.

Violation of protodiastole can be associated with various heart diseases, such as arrhythmias, coronary heart disease, heart failure, etc. In this case, protodiastole may be shortened or absent altogether.

Thus, protodiastole plays an important role in the work of the heart and is one of the key stages of the cardiac cycle. Violation of protodiastole may indicate the presence of serious heart disease and requires timely treatment.

Introduction.

The cardiac cycle is the process that occurs in the human heart and allows it to pump blood throughout the body. During the cardiac cycle, the heart goes through a series of conditions that depend on its filling with blood and the tension of the heart muscles. One of these states is protodiastole, which lasts a very short time, but
