Cardiovascular physiology is the study of the circulatory system. More specifically, it addresses the physiology of the heart ("cardio") and blood vessels ("vascular").

These subjects are sometimes addressed separately, under the names cardiac physiology and circulatory physiology.

Biology Measurement Rate

Heart rate refers to the speed of the heartbeat, specifically the number of heartbeats per unit of time. The heart rate is typically expressed as beats per minute (bpm). The heart rate can vary according to the body's physical needs, including the need to absorb oxygen and excrete carbon dioxide. Activities that can provoke change include physical exercise, sleep, illness, ingesting, and drugs.

The normal human heart rate ranges from 60–100 bpm. Bradycardia refers to a slow heart rate, defined as below 60 bpm. Tachycardia refers to a fast heart rate, defined as above 100 bpm. When the heart is not beating in a regular pattern, this is referred to as an arrhythmia. These abnormalities of heart rate sometimes, but not always, indicate disease.

Heart

Rate pressure product, also known as Cardiovascular Product or Double Product, is used in cardiology and exercise physiology to determine the cardiovascular risk of subjects.

Rate Pressure Product (RPP) = Heart Rate (HR) * Systolic Blood Pressure (SBP)

Heart Rhythm Meditation (HRM) is an ancient method of meditation that has been expanded and developed by Puran Bair and Susanna Bair of the Institute for Applied Meditation. The method was described in the 1998 book Living from the Heart, by Puran Bair (2nd Edition Published in 2009) and in the 2007 book Energize Your Heart in 4 Dimensions, by Puran and Susanna Bair.

All meditation methods are effective in reducing stress, but they do so in different ways. For example, the earliest methods meant to explore the field of consciousness beyond the physical universe, as the material world was seen as illusory and limiting. As a by-product, these methods eliminate stress by creating detachment. In contrast, modern methods of meditation honor the physical world as the final step in spirituality, and honor the problems of life as the stimuli of growth. They do not create detachment; they create creativity. The aim of Heart Rhythm Meditation is to pull the richness of the universe into the person, and anchor it in the heart, expanding the heart faculty. The goals are to increase creativity, courage and compassion; Heart Rhythm Meditation is a path in life. Stress is reduced by increasing an individual's capacity.

Anatomy

Cardiac dysrhythmia (also known as arrhythmia or irregular heartbeat) is any of a group of conditions in which the electrical activity of the heart is irregular or is faster or slower than normal. The heartbeat may be too fast (over 100 beats per minute) or too slow (less than 60 beats per minute), and may be regular or irregular. A heart beat that is too fast is called tachycardia and a heart beat that is too slow is called bradycardia. Although many arrhythmias are not life-threatening, some can cause cardiac arrest.

Arrhythmias can occur in the upper chambers of the heart, (atria), or in the lower chambers of the heart, (ventricles). Arrhythmias may occur at any age. Some are barely perceptible, whereas others can be more dramatic and can even lead to sudden cardiac death.

The circulatory system is an organ system that permits blood and lymph circulation to transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, blood cells, etc. to and from cells in the body to nourish it and help to fight diseases, stabilize body temperature and pH, and to maintain homeostasis.

This system may be seen strictly as a blood distribution network, but some consider the circulatory system as composed of the cardiovascular system, which distributes blood, and the lymphatic system, which returns excess filtered blood plasma from the interstitial fluid (between cells) as lymph. While humans, as well as other vertebrates, have a closed cardiovascular system (meaning that the blood never leaves the network of arteries, veins and capillaries), some invertebrate groups have an open cardiovascular system. The more primitive, diploblastic animal phyla lack circulatory systems. The lymphatic system, on the other hand, is an open system providing an accessory route for excess interstitial fluid to get returned to the blood.
