Referring to the time when the heart is in a period of relaxation and dilatation (expansion). cf. systolic.
The lower number of a blood pressure reading signifying the myocardial and arterial relaxation between pump strokes. Too close to the higher number (systolic) usually signifies inadequate relaxation of the heart and arteries between heartbeats.
The second number in a blood pressure reading that measures the pressure in the arteries during the relaxation phase of the heartbeat.
In the wondrous realm of blood circulation, there exists a captivating phase wherein the pumping chambers of the heart, known as ventricles, undergo a process of replenishment, graciously accepting the life-giving fluid. This remarkable stage showcases the ventricles in a state of utmost relaxation, poised to receive the vital crimson sustenance. Simultaneously, the arterial walls experience a significant reduction in pressure, reaching their lowest ebb during this exquisite spectacle. This harmonious interplay between the heart’s rhythmic dance and the arterial landscape underscores the intricacies of our cardiovascular system, embodying a delicate equilibrium of forces that ensures the perpetuation of life itself.
