In this lab my group and I measured Alexis's heart beat. A single heart beat contains five components which are P,Q, R, S, and T. P is the start of the impulse that spreads to the sinoatrial node downward from the atria to the atrioventricular node and to the ventricles. The QRS wave occurs when the ventricles contract, then the pulse travels septum then it travels up the outer walls. The T wave is the recovery (re-polarization) of the heart and you may notice that the T wave is a little big in this graph due to our equipment. The times it took the R wave to reach it's peak in our lab is listed below. After looking at them you can come to the conclusion that Alexis's electrical pulses occurred every 0.8 or estimating 75 beats per a minute.
