Question
The relationship between cardiac output, heart rate and stroke volume is defined as:Question 1Select one:a.Heart rate = cardiac output / stroke volumeb.Cardiac output = stroke volume / heart ratec.Stroke volume = cardiac output X heart rated.Cardiac output = heart rate / stroke volume
Solution
Para responder a la pregunta, primero debemos entender las definiciones de los términos involucrados:
- Cardiac output (gasto cardíaco): Es el volumen de sangre que el corazón bombea por minuto.
- Heart rate (frecuencia cardíaca): Es el número de latidos del corazón por minuto.
- Stroke volume (volumen sistólico): Es el volumen de sangre bombeado por el corazón en cada latido.
La relación entre estos términos se expresa mediante la fórmula:
Ahora, revisemos cada opción:
a. Heart rate = cardiac output / stroke volume
- Despejando la frecuencia cardíaca de la fórmula original:
- Esta opción es correcta.
b. Cardiac output = stroke volume / heart rate
- Esta opción no es correcta porque la fórmula correcta es:
c. Stroke volume = cardiac output X heart rate
- Esta opción no es correcta porque la fórmula correcta es:
d. Cardiac output = heart rate / stroke volume
- Esta opción no es correcta porque la fórmula correcta es:
Por lo tanto, la respuesta correcta es:
a. Heart rate = cardiac output / stroke volume
