Is it possible for your heart to go into fibrillation if you exceed your maximal heart rate?

Your maximal heart rate is 220 - MINUS your age. In most human their MHR is about 200- 220 BPM. Maximal heart rate is the highest number of times per minuet that you heart could contract during maximal physical exersion. It is unlikely for your heart to go into Fibrillation at heart rates of 200 - 250 BPM. Fibrillation occurs at heart rates of 300- 600 BPM and can be causes by Heart disease Electrical shock Heart attacks Heart Arrhythmia

Of maximal heart rate percent submax or submaximal equates to what?
Submaximal usually equates to about 70-85 percent of maximal heart rate (MHR).
How and why does aging affect the maximal heart rate?
Young children generally have a maximal heart rate approaching 220 beats per minute. This maximal rate falls throughout life. By age 60 maximal heart rate in a group of 100 men will average about 160 beats per minute. This fall in heart rate seems to be a linear process so that maximal heart rate can be estimated by the formula 220- AGE. This is an ESTIMATE, however. If we actually measure the maximal heart rates of those same 100 men during a maximal exercise test we would probably see a range of heart rates between 140 and 180. There is no strong evidence to suggest that training influences the decline in maximal heart rate. This reduction appears to be due to alterations in the cardiac electrical conduction system (SA node and Bundle of His), as well as down regulation of beta-1 receptors, which decreases the heart's sensitivity to catecholamine stimulation.
Is atrial fibrillation worse that ventricular fibrillation?
No, ventricular fibrillation is worse than atrial fibrillation. This is because the ventricle is the chamber responsible for the main force pumping the blood out of the heart. If this contraction is not coordinated (like when fibrillation occurs), then the heart will not be able to function and consciousness will be lost within a few seconds. Ventricular fibrillation may result from electric shock, major myocardial infarct or some anaesthetic drugs. Resuscitation is usually possible by applying an electric shock (defibrillation) - which causes all cells to enter the refractory period and gives the sinoatrial node a chance to resume its normal pacemaker activity.
What is atrial fibrillation and flutter?
abnormal heart rhythms in which the atria, or upper chambers of the heart, are out of sync with the ventricles, or lower chambers of the heart. In atrial fibrillation, the atria "quiver" chaotically and the ventricles beat irregularly
What is the condition of rapid and irregular or out of phase heart contractions?
fibrillation
What is a possible reason for lower maximal heart rates observed in endurance-trained athletes?
Slower heart rates increase ventricular filling time
Of maximal heart rate percent submax or submaximal equates to what?
Submaximal usually equates to about 70-85 percent of maximal heart rate (MHR).
What is an atrial fibrillation?
An atrial fibrillation is a cardiac arrhythmia which involves the upper two chambers of the heart.

How do you use the word fibrillation in a sentence?
The E.K.G. showed his heart was in fibrillation.Fibrillation of the heart muscle means the heart cannot contract effectively.If doctors cannot stop fibrillation, the heart muscle can stop working.
Is atrial fibrillation worse that ventricular fibrillation?
No, ventricular fibrillation is worse than atrial fibrillation. This is because the ventricle is the chamber responsible for the main force pumping the blood out of the heart. If this contraction is not coordinated (like when fibrillation occurs), then the heart will not be able to function and consciousness will be lost within a few seconds.

What does fibrillation mean in medical terms?
Fibrillation is a medical term meaning an interruption of electrical activities in the heart. The most common types of fibrillation are atrial fibrillation and ventricular relation, termed as AFib and VFib, respectively.
What is atrial fibrillation and flutter?
abnormal heart rhythms in which the atria, or upper chambers of the heart, are out of sync with the ventricles, or lower chambers of the heart. In atrial fibrillation, the atria "quiver" chaotically and the ventricles beat irregularly
What is the medical term meaning abnormal heart rhythm that causes the ventricles to quiver?
Atrial fibrillation is the medical term meaning the irregular, uncoordinated, ineffective twitching contraction of the walls of the atria. A related condition is ventricular fibrillation, which occurs in the lower chambers of the heart.
How can ventricular fibrillation be prevented?
A healthy lifestyle to reduce the risk of heart diseases which lead to ventricular fibrillation is the best prevention.
What is the condition of rapid and irregular or out of phase heart contractions?
fibrillation
A quivering or spontaneous muscle contraction of the heart is called?
fibrillation
