Parameter At rest During exercise

Heart rate (HR) 60 beats min^–1 100 beats min^–1

Stroke volume (SV) 60 mL 108 mL

Based on the above given data, during exercise cardiac output increased by how many times?

मापदण्ड विश्रामावस्था व्यायाम के दौरान

हृदय दर (HR) 60 स्पन्द मिनट^–1 100 स्पन्द मिनट^–1

प्रवाह आयतन (SV) 60 मिली. 108 मिली.

Q. A patient went to see a cardiologist complaining about being tachycardic. Upon examination, his heart rate was found to be 90 beats per minute; his end-diastolic volume was found to be 140 mL per minute whereas his end-systolic volume was 60 mL per minute. What was his calculated cardiac output per minute?

एक रोगी टेकीकार्डिएक की शिकायत लेकर हृदयरोगविशेषज्ञ के पास गया। जाँच करने पर उसकी हृदय दर 90 स्पंद प्रति मिनट पायी गई थी, उसका अंत्य अनुशिथिलन आयतन 140 मिली. प्रति मिनट जबकि उसका अंत्य प्रकुंचन आयतन 60 मिली. प्रति मिनट पाया गया था। उसका प्रति मिनट परिकलित हृदय निकास क्या था?

If end diastolic volume and end systolic volume of a person is about 130 ml and 50 ml respectively, then calculate the cardiac output of the person (heart rate 80/min) for 5 minutes.

यदि किसी व्यक्ति का अंत्य अनुशिथिलन आयतन और अंत्य प्रकुंचन आयतन क्रमशः लगभग 130 मिली. तथा 50 मिली. है, तब 5 मिनट के लिए व्यक्ति के हृदय निकास (हृदय दर 80 / मिनट) की गणना कीजिए।
