The "pacemaker" of the heart is the A. SA node. B. AV node. C. AV septum. D. ventricle. Blood Flow in the Heart: The heart is the major organ of the cardiovascular system and receives and delivers blood to and from all parts of the body. All deo...
The heart has a regulatory system, known as the intrinsic conduction system, that determines the pace of the heartbeat. Learn about the intrinsic conduction system, including the SA node, AV node, the bundle of His, bundle branches,...
The sinoatrial node (SAN) is the natural pacemaker of the heart that is composed of pacemaker cells [1]. Sick sinus syndrome (SSS) is usually caused by the disorders of SAN impulse formation or SAN-to-atrial impulse conduction, which comprises a sinoatrial block, sinus bradycardia, and sinus...
pacemaker 显示所有例句 n. 1. (心脏)起搏器an electronic device that is put inside a person's body to help their heart beat regularly 2. 领跑人;领跑动物a person or an animal that begins a race quickly so that the other people taking part will try to copy the speed and run a fast race...
If the SA nodes fail to serve as a pacemaker, then responsibility for setting the pace of the heart may be passed to the ___ which fires at approximately ___ beats per minute. If this part of the conduction system also fails, then autor...
There is a question: how highly available will be such high available cluster? To research this was developed a test bed, which imitates failures of a cluster node, waits for recovery, fixes failed node and cyclically continue testing.
Cardiac pacemaker cells of the sinoatrial node initiate each and every heartbeat. Compared with our understanding of the constituents of their electrical excitation, little is known about the metabolic underpinnings that drive the automaticity of pacemak
Heart The heart acts as a pump and maintains circulation of the blood by alternate concentration and relaxation of cardiac muscle (the myocardium). It generally contracts at
英语翻译ECG (electrocardiogram) is a test that measures the electrical activity of the heart.The heart is a muscular organ that beats in rhythm to pump the blood through the body.The signals that make the heart's muscle fibres contract come from the sino
Conditions that cause pacemaker formation in the developing heart are poorly understood. Embryonic rat myocardium grafted into the anterior eye chamber of an adult rat provides a promising model system in which to study pacemaker development. Electrophysiologic map- ping with two microelectrodes showed ...
