Because cardiac muscle is only able to depolarize after repolarization and the extrasystole cannot occur until relaxation. 1. Explain the effect that extreme vagus nerve stimulation had on the heart. When the extreme vagus nerve stimulation was being stimulated, the heart rate decreased. 2. during which proportion of the cardiac cycle was it possible to induce an extrasystole ?

Extrasystole is quizlet

In an attempt to restore blood pressure, the parasympathetic outflow to the heart is decreased and sympathetic outflow is increased. Why is it only possible to induce an extrasystole during relaxation? Your answer: the cardiac muscle is only able to depolarize after it repolarizes because of the long refractory period, so the extrasystole is not able yo occur until the relaxation period. 3. Explain why wave summation and tetanus are not possible in cardiac muscle tissue. Study Flashcards On A&P II Lab Practical 2 at Cram.com.

With the development of the right bundle branch block, the extrasystole must activate the His retrograde and exit to the ventricle via the left bundle branch resulting in an H-V interval that is equivalent to that during a conducted beat. Extrasystole is the most popular, as it is found in 70% of people. It can be defined at any age, there is also no connection between pathology and gender and constitutional features. The predisposing factors of the development of extrasystoles include arterial hypertension, ischemic heart disease, heart disease, lack of potassium and magnesium in the blood, as well as sex and age.
