Arrhythmia

Question 1

Causes of Bradycardia

Answer 1

D- drugs
I- ischemia
N- neurogenic shock
E- electrolytes

Question 2

Absolute refractory period

Answer 2

Or the effective refractory period phase 0-3 which an electrical stimulus will not elicit an action potential because the membrane has not sufficiently depolarizer and sodium channels are not yet recovered

Question 3

Relative refractory period

Answer 3

Phase start of 3-4
Requires a large stimulus to activate action potential

Question 4

Supranormal phase

Answer 4

Phase end of 3-4 where arrhythmia is likely to occur because the action potential threshold is lower than normal
