Produced when a signal from the SA node spreads through the atria on a ECG - Answer- P-Wave Detects electrical current in the heart - Answer- Electrocardiogram Generated by ventricular repolarization - Answer- T-Wave produced when signal from AV node spreads through ventricular myocardium and depolarizes muscle - Answer- QRS complex The heart beats due to this - Answer- autorhythmicity Charge shifts from negative to positive - Answer- Depolarization Nerve like process that spre...

Rush - Advanced Pharmacology - NSG 531 - Exam 3 Questions with Complete Solutions what is the difference between cardiac myocyte action potential and that of the CNS or ANS? - Correct Answer nerve cell action potential is very short cardiac action potential is much longer they are longer to have adequate filling time in order to get a good contraction for a reasonable bolus of blood the only way this can happen is if the action potential is longer this will also mean that the refractory per...
