Which of the following is not correctly matched?
Tachycardia - Heart rate is 70-75 beats
When the heart pumps blood into the systemic circulation, it does so with a huge amount of pressure. This pressure becomes a waveform that travels through the arteries ahead of the actual column of the blood which is pumped out. This waveform creates the throbbing sensation we feel when we palpate peripheral arteries. This is what we call the pulse. The normal pulse or heart rate is around 70 to 75 times per minute averaging at 72 beats per minute. Atrial fibrillation is where the ineffective pumping of the heart becomes insufficient to produce waveforms that can reach the periphery. Any heart rate above 100 beats per minute is considered tachycardia and anything below 60 beats per minute is called bradycardia.
