A line does have infinite length because it exists on an infinite plane. The only time it does not have infinite length is when it is a line segment.
nanosecond.
A point. (Also time, language, concepts, etc.)
It depends on the time of day, and, therefore, it depends on where the sun is in the sky.
Instead of counting out all of the square units and determining by having a real life situation and measuring a certain amount of length to measure each and every individual square, you multiply the length times the width to save hours of time.
Atrial refers to the top portion of the heart and diastole is when the heart is at rest. Atrial diastole would be when the top portion of the heart is not beating.
Diastole is when a given chamber of the heart is relaxing. There is atrial diastole and ventricular diastole. Most of the time when talking about diastole we are referring to the ventricular because that is when we measure the diastolic (low) pressure in your systemic arteries, usually the brachial artery.
Atrial diastole is the phase of the cardiac cycle when the atria relax and fill with blood. It typically lasts about 0.7 seconds during a normal heart cycle at a resting heart rate of around 70 beats per minute. This duration can vary based on heart rate and physiological conditions. During rapid heart rates, atrial diastole may be shorter, impacting filling time.
At diastole the muscles of the atria and ventricles relax and blood flows into the heart. Therefore the atria and ventricles and at rest together during diastole.
No it does not. Atrial repolarization is generally not visible on the telemetry strip because it happens at the same time as ventricular depolarization (QRS complex). The P wave represents atrial DEpolarization (and atrial systole). Atrial repolarization happens during atrial diastole (and ventricular systole).
The third apsect of the cardiac cycle is the rest period, however it is not separate from the sytole and diastole. It is merely the time frame during a cycle when both the artia and ventricles are in disastole at the same time. It thus can be said that the period of rest overlaps atrial and ventricular diastole.
Relaxation = Diastole Contraction of the atria=Atrial systole Contraction of the ventricles = Ventricular systole
Dysrhythmias that cause a loss of atrial kick include atrial fibrillation and atrial flutter. In these conditions, the atria do not contract effectively, leading to reduced blood flow into the ventricles during diastole. This loss of atrial kick can significantly impact cardiac output, particularly in patients with underlying heart conditions. Other dysrhythmias, such as complete heart block, can also affect atrial contraction and contribute to this phenomenon.
The heart spends more time in diastole.
The stage of the cardiac cycle that precedes the resting period is known as diastole. During diastole, the heart relaxes and fills with blood before contracting again during systole.
Cardiac cycle, which is made up of atrial and ventricular systole and diastole.
Systole is when a chamber of the heart (i.e. atrial vs. ventricular systole) is contracting. Diastole is when a chamber of the heart is relaxing. Without qualifying which chamber it is usually assumed to mean the left ventricle.Systole refers to when the heart is contracted and diastole refers to when the heart is relaxed.
