Answer:
Ventricular fibrillation a type of arrhythmia characterized by a very fast heart rate which causes no blood to reach vital organs causing cardiac arrest.While Atrial fibrillation is an atrial tachyarrhythmia characterized by the fact that the atria beat in an uncoordinated way at a very high rate that exceeds 350 beats per minute. As a result, the atria are no longer effective in pumping blood to the ventricles.
Explanation:
Under normal conditions the heart contracts rhythmically and synchronously. This contraction is the result of an electrical impulse that is generated in the atrium, reaches the ventricle and results in a heartbeat. In an arrhythmia there is an alteration of this mechanism that leads to the heart not contracting regularly, generating a rhythm disorder. The contraction of the ventricles pumps blood to the rest of the body. In ventricular fibrillation, the heart rhythm is very fast and chaotic (up to 300 beats per minute) and is characterized by not being able to provoke an efficient heart beat. Thus, the lack of contraction of the ventricles causes the blood to barely be pumped from the heart, producing a collapse of the cardiovascular system and cardiac arrest. Atrial fibrillation is characterized by disorganized and very rapid atrial activity (350-600 beats / min). This leads to an irregular ventricular response (150-200 beats / min) and an irregular pulse.During atrial fibrillation, the atrial contraction that helps fill the ventricles with blood is lost; this can significantly reduce cardiac output, particularly in patients with mitral stenosis, hypertension, or hypertrophic cardiomyopathy.It is associated with an increased risk of thromboembolism (formation of blood clots in the heart that can dislodge and go through the bloodstream until impacted on the a blood vessel, causing lack of irrigation in that area) and therefore stroke (cerebral thromboembolic accident).
Answer:
Running Is a very important physical activity. It is needed in everyday life, and it should be practiced to keep your body healthy. Younger children should run a lot, that's why sports are so encouraged in school.
Running can significantly improve physical and mental health. As a form of aerobic exercise, running can reduce stress, improve heart health, and even help alleviate symptoms of depression. Some researchers think running may be so good for us because it's something we evolved to do.
Even only running for 30 minutes is great for you. One 30 minute run is guaranteed to burn between 200-500 calories. That's a fantastic step forwards to your weight loss goal. Or a guilt-free guilty pleasure that day. Or splitting the bottle instead of having a glass.
Explanation:
Answer : The four psychological factors that affect how well a person adheres to an exercise program are;
1) Self motivation with self-awareness - When a person becomes aware about his health and body he starts working for it to maintain and keep themselves fit. Self motivation will help the person to continue the habit of exercising.
2) Personal Goal Setting - This is one of the important point for setting an individual goal for exercise and achieve that state of physical fitness freedom.
3) Self - efficacy - It is the time when a person will overcome barriers in physical exercises and will gain the boost and confidence to perform exercise with proper dedication, which will avoid relapse.
4) Physical activity environment - If the person who is undergoing daily training for physical fitness will perform better, because the surrounding environment will encourage that individual to stay motivated and achieve their fitness goal.
The most important amongst all is self-motivation, without which no individual can adhere to the regime and achieve their fitness goal.
