Given a condition where no part of the atrial tissue was active, what would be the approximate resulting heart rate? Group of answer choices: 0 beats per minute (because they would be dead), 30 beats per minute, 50 beats per minute, 70 beats per minute.

Sino-Atrial node (SAN) can generate impulses (a) $70-75 \mathrm{~min}^{-1}$ (b) $50-55 \mathrm{~min}^{-1}$ (c) $35-40 \mathrm{~min}^{-1}$ (d) $90-100 \mathrm{~min}^{-1}$
If the frequency of human heart is $1.25 \mathrm{~Hz}$, the number of heart beats in 1 minute is (a) 65 (b) 75 (c) 80 (d) 90
