References in classic literature ?
For three hundred years and more the long steadily accelerated diastole of Europeanised civilisation had been in progress: towns had been multiplying, populations increasing, values rising, new countries developing; thought, literature, knowledge unfolding and spreading.
Three hundred years of diastole, and then came the swift and unexpected systole, like the closing of a fist.
Lydgate talked persistently when they were in his work-room, putting arguments for and against the probability of certain biological views; but he had none of those definite things to say or to show which give the waymarks of a patient uninterrupted pursuit, such as he used himself to insist on, saying that "there must be a systole and diastole in all inquiry," and that "a man's mind must be continually expanding and shrinking between the whole human horizon and the horizon of an object-glass." That evening he seemed to be talking widely for the sake of resisting any personal bearing; and before long they went into the drawing room, where Lydgate, having asked Rosamond to give them music, sank back in his chair in silence, but with a strange light in his eyes.
POLARITY, or action and reaction, we meet in every part of nature; in darkness and light; in heat and cold; in the ebb and flow of waters; in male and female; in the inspiration and expiration of plants and animals; in the equation of quantity and quality in the fluids of the animal body; in the systole and diastole of the heart; in the undulations of fluids, and of sound; in the centrifugal and centripetal gravity; in electricity, galvanism, and chemical affinity.
Left atrium is directly exposed to LV pressures in diastole. Chronic sustained elevation of elevated diastolic filling pressures result in left atrial remodeling resulting in its enlargement.
The counter-argument to this is that the cardiac blood supply is unique, with the majority of the myocardium being perfused during diastole. [7] Conceivably, ischaemia could result from partial coronary artery spasm due to hypocalcaemia if diastolic myocardial blood flow decreased below a critical threshold, thereby causing a supply--demand mismatch.
Friedreich described the appearance of the jugular veins during systole and diastole:
Bradycardia is a noted feature of breath-hold immersion of the face in water, due to which the ventricular diastole will be prolonged, which in turn will lead to an increase in the LV EDV.
Where: LVIDD = Left Ventricular Internal Diameter in Diastole
The non-compacted to compacted ratio was more than 4:1 during diastole. These findings were consistent with the diagnosis of left ventricular non-compaction cardiomyopathy.
The team found that 60 minutes after meditating the 14 study participants showed lower resting heart rates and reduction in aortic pulsatile load - the amount of change in blood pressure between diastole and systole of each heartbeat multiplied by heart rate.
The results of echocardiography at that age were ejection fraction of 69%, interventricular septum diameter in systole of 8 mm (normal value=3.5-5 mm), interventricular septum diameter in diastole of 7 mm (normal value=3.5-5 mm), and posterior wall diameter of 9 mm in systole and 7 mm in diastole (normal value=3.5-5 mm).
