Cardiovascular System Laboratory Analysis

The Cardiovascular System Laboratory delves into heart function systematically, scrutinizing the impact of blood pressure on cardiac performance. This involves dissecting the ramifications of blood pressure fluctuations on patients, as evidenced by laboratory findings. This article elucidates standard blood pressure levels, associated thresholds of concern, optimal heart rates, and parameters delineating a healthy heart rhythm. Moreover, it investigates the nexus between heart rate and blood pressure, interprets cardiovascular laboratory outcomes, and proposes lifestyle adjustments grounded in the laboratory assessments.

Understanding Blood Pressure

Blood pressure denotes the force exerted as blood courses from the heart to the body. Diastolic pressure characterizes the force exerted as the heart expels blood, whereas systolic pressure represents the resting pressure amid cardiac cycles. The optimal blood pressure spectrum spans approximately 90/60 mm Hg to 120/80 mm Hg (National Health Service, 2019). Hypertension manifests when persistently elevated blood pressure surpasses 130/80 mm Hg, often amenable to lifestyle modifications. Blood pressure readings in the range of 140/90 mm Hg or beyond necessitate immediate medical intervention and attention (National Health Service, 2019).

Understanding Heart Rate

Heart rate delineates the count of heartbeats per minute requisite to fulfill the body’s oxygen requisites (Harvard Health Publishing, 2020). It is noteworthy that an escalated heart rate doesn’t invariably denote high blood pressure (Beckerman, 2002). Resting heart rate mirrors the heart’s function during bodily rest, with 60 to 100 beats per minute construed as a healthy bracket (American Heart Association, 2021). Maximum heart rate, attained during rigorous activity, can be computed using the formula 220 minus the individual’s age (American Heart Association, 2021). Irregular heart rates, surpassing 120-140 bpm or plummeting below 60 bpm, instigate concerns regarding the individual’s well-being (Mayo Clinic, n.d.).

Correlation between Heart Rate and Blood Pressure

Persistently elevated blood pressure poses a notable health hazard and serves as a risk element for cardiovascular maladies. Elevated heart rate frequently accompanies hypertensive individuals and is regarded as a contributor to hypertension and other cardiovascular ailments (Dalal et al., 2019). Positive correlations exist between heightened heart rate and cardiovascular morbidity, potentially culminating in premature mortality (Goorakani et al., 2020).

Cardiovascular Findings in Patients and Lifestyle Enhancement

Patient 1: Tanya Age: 40 Complaint: Frequent headaches Blood Pressure Test: 125/80 mm Hg (pre-hypertension) Heart rate Test: 66-72 bpm (normal)

Patient 2: Caroline Mendoza Age: 45 Complaint: Persistent high blood pressure Blood Pressure Test: 140/90 mm Hg (intense high blood pressure) Heart rate Test: 135 bpm (alarming situation)

Conclusion

Blood pressure, epitomizing the force exerted by the heart during blood propulsion, ideally remains beneath 120/90 mmHg, with persistent elevations indicative of high blood pressure. Heart rate, denoting the rhythm at which the heart contracts in a minute, exhibits variances in resting and maximum thresholds, with the latter contingent on the individual’s age. Hypertension poses a substantial health peril and serves as a contributing factor to cardiovascular afflictions.
