Flashcard 15: Atrial _____ is preceded by the P wave on ECG, which marks depolarization of the atria
Answer: systole

Flashcard 16: The increase in atrial pressure caused by atrial systole appears on the venous pulse curve as the _____ wave
Answer: a
Extra:
The 'a' wave appears as contraction of the right atrium because the jugular venous pulse is measured on the venous side - this distinction comes into play for right vs left sided AV valve problems. Notice how the 'a' wave hight is a little higher than the 'v' wave height
How the 'a' wave changes based on different pathologies. Mainly focus on Tricuspid regurgitation & stenosis, and Atrial fibrillation:

increased JVP without inspiratory decline is known as Kussmaul's sign; may also have prominent x & y descents on jugular venous pulse tracings and a pericardial knock (mid-diastolic sound) on PE
