4 kwi 2015 · Core tip: The function of the heart is to contract and pump oxygenated blood to the body and deoxygenated blood to the lungs. To achieve this goal, a normal human heart must contract regularly and continuously, and respond to the changing requirements of the body’s tissues.
Lung function encompasses airway flow, volumes and capacities, and oxygenation. The anatomic and physiologic continuity of the lungs with the heart and vessels intuitively suggests that impairments in any component of lung function may impact cardiovascular health.
24 sty 2021 · The aim of this review is to detail how heart rate is homeostatically controlled by the autonomic nervous system, how heart rate can impact on pathophysiological processes, and how heart rate variability and heart rate recovery time may be used in the clinical setting to allow the neurocardiac system to be assessed.
7 lut 2019 · This work offers a novel experimental design and applies the concept of instantaneous phase to detect cardio-respiratory entrainment at elevated respiration rates, close to the resting heart...
18 paź 2023 · Prednisone, a steroid drug used to treat inflammation, can cause heart palpitations (skipped, pounding, or racing heartbeats) as well as other cardiac side effects like bradycardia (slowed heartbeats), tachycardia (rapid heartbeats), and atrial fibrillation (irregular heartbeats).
Identify cardiovascular centers and cardiac reflexes that regulate heart function. Describe factors affecting heart rate and force of contraction. Explain the connection between preload, contractility, afterload and stroke volume. Distinguish between positive and negative inotropic factors.
16 lip 2023 · In this article, we will discuss how hormones and nerve impulses work to control the heart rate and the baroreceptor reflex, which can change the heart rate. Sinoatrial Node (SAN) and Atrioventricular Node (AVN)
