A cardiac arrest is the same as death. It’s just semantics. After a gunshot wound, if the person hemorrhages sufficiently, then the heart stops beating and they die. The social perception of death is that you have reached a point from which you can never come back, but medically speaking,Read More →
Transmitting data from a monitor to a distant monitoring station is known as telemetry or biotelemetry. Cardiac monitoring in the ED setting has a primary focus on the monitoring of arrhythmia, myocardial infarction, and QT-interval monitoring. What are the two types of cardiac monitoring? Common types of cardiac monitoring systemsRead More →
A cardiac cycle is defined as the steps involving the conversion of deoxygenated blood to oxygenated blood in the lungs and pumping it by the heart to the body through the aorta . What is the function of cardiac cycle? The cardiac cycle is a series of pressure changes thatRead More →
Cardiac and most smooth muscles are autorhythmic-they are capable of contracting spontaneously without nervous or hormonal stimulation. What is cardiac Autorhythmic? The heartbeats of the heart are autorhythmic, which means the heart produces its own pulses through electrochemical stimuli originating from a small group of cells in the wall ofRead More →
Phosphorylation of cardiac sarcomeric proteins plays a major role in the regulation of physiological performance of the heart. Tropomyosin, an essential thin filament protein, regulates muscle contraction and relaxation through its interactions with actin, myosin, and the troponin complex. Do all muscles have tropomyosin? Nonmuscle tropomyosin isoforms function in allRead More →
Physical exercise, emotional shock, etc. always lead to an increase in heart rate. Increased heart rate means an increase in cardiac output. Amount of stroke volume is determined by amount of blood coming inside heart during diastole. What increases cardiac output quizlet? An increase in heart rate increases cardiac output.Read More →
When sudden cardiac arrest occurs, reduced blood flow to your brain causes unconsciousness. If your heart rhythm doesn’t rapidly return to normal, brain damage occurs and death results. Survivors of cardiac arrest might show signs of brain damage. Can cardiac arrest happen without pain? Shortness of breath can occur withRead More →
The main causes of cardiac arrest related to the heart are: a heart attack (caused by coronary heart disease) cardiomyopathy and some inherited heart conditions. congenital heart disease. heart valve disease. acute myocarditis (inflammation of the heart muscle). Can cardiac arrest happen to anyone? Sudden cardiac arrest can happen inRead More →
Muscle: Muscle regeneration These are mononucleated quiescent cells. When the muscle is damaged, these cells are stimulated to divide. After dividing, the cells fuse with existing muscle fibres, to regenerate and repair the damaged fibres. What cardiac muscle cells are damaged by a heart attack they are usually replaced by?Read More →
