If the cycle stas with ' a ' wave of jvp . Arrange the following in order-
(A) R wave (B) T wave (C) 1st hea sound and Rapid ejection phase (D) All
(D) Answer- D. AllThe "a" wave is approximately synchronous with the first hea sound (S1) and just precedes the carotid upstroke.Sholy after the a-wave there is a second peak , the c-wave. The c-wave immediately follows the r wave of the ECG waveform.The v-wave corresponds to the end of the t wave in the ECG waveform.
