Question

Альпинист 5 часов поднимался на вершину. Его сердце билось с частотой 80 ударов в минуту. Сколько часов за время подъёма желудочек сердца альпиниста находился в состоянии систолы?

Answer 1

3 часа
5 делим на 2 получаем 2 с половиной + пол часа перекур получается три часа
НЕ ЗА ЧТО

Answer 2

Calculation of the Duration of Ventricular Systole

To calculate the duration of ventricular systole during the ascent, we need to know the heart rate (number of heartbeats per minute) and the duration of the cardiac cycle (the time it takes for one complete heartbeat).

Given that the heart rate of the mountaineer is 80 beats per minute, we can calculate the duration of each cardiac cycle using the formula:

Cardiac Cycle Duration = 60 / Heart Rate

Substituting the given heart rate value, we get:

Cardiac Cycle Duration = 60 / 80 = 0.75 minutes

Since the mountaineer spent 5 hours ascending, we need to convert this time to minutes:

Time of Ascent = 5 hours * 60 minutes/hour = 300 minutes

To calculate the number of cardiac cycles during the ascent, we divide the total time of ascent by the duration of each cardiac cycle:

Number of Cardiac Cycles = Time of Ascent / Cardiac Cycle Duration

Substituting the given values, we get:

Number of Cardiac Cycles = 300 minutes / 0.75 minutes = 400 cycles

Therefore, the mountaineer's ventricles were in a state of systole for 400 cycles during the ascent.
